->''"APRIL FOOL, n.: The March fool with another month added to his folly."''
-->--'''Creator/AmbroseBierce''', ''Literature/TheDevilsDictionary''

A long time ago, April 1st was the start of the new year, and after it was officially changed to January 1st, people who still celebrated at the old date were dubbed "April Fools". Or possibly the term originally referred to people who prematurely celebrated the start of summer (which was traditionally May Day, May 1, in many ancient cultures), only to be met with lingering snowfall; the exact origin is unclear. Regardless of where the term originated, it has since become something much sillier.

April 1 is known as April Fools' Day, where almost every single person in the world becomes TheFool. A time to trick {{Muggles}} that the joke is real, and a time to pull pranks and tricks. You will then reveal the trick with the line "April Fools!"

Many works of the media include April Fools' Day jokes: usually articles presented as news or truth that go beyond the limits of sense, contain blatant inaccuracies, would be completely outrageous etc. They usually assume ViewersAreGeniuses and that no one would be stupid enough to take it seriously, but of course that's not always true. People are often taken in, get outraged, get laughed at, get to made feel stupid. A good time is had by all.

In the 1990s and early 2000s, a common April Fools' Day Joke on {{Webcomics}} was for two different webcomic authors to each do the other's strip. By far the most popular joke on the Internet seems to be a claim by the owner that the website is shutting down. A common joke specific to fansites is to suddenly denounce what the fansite stood for and revamp it to focus on a different franchise, most commonly one that bears similarities to the original, or even a competing one. Another joke specific to gaming sites with free content is the introduction of a "[[BribingYourWayToVictory premium]]" version of the site, where it's said one gets exclusive content if one pays for it; generally, the site makes "preview content" available, with most of the "premium perks" turning out to be silly (or duplicates of free services by other sites devoted to the game).

Subversions of April Fools' Day are to have something improbable published on that day be actually true (either on that day or on a later date, or when a prank goes [[DudeNotFunny just a little too far]]).

In any case, woe betide someone who dies (or worse, is ''born'') on April Fools' Day. [[http://en.wikipedia.org/wiki/1946_Aleutian_Islands_earthquake And God help you if a natural disaster happens and people think the blaring sirens are a prank.]]

!!Real Examples


* The mouthwash company Scope used the couple of days leading to April 1st, 2013 to advertise a bacon-flavored mouthwash. Consumer reactions were overwhelmingly positive, and there were plenty of people [[http://money.msn.com/now/post.aspx?post=12dc81a5-15ad-4ef6-8b8e-3c7014fb5983 ticked off to find out it was all a joke]].
* On April 1, 1996, Taco Bell took out newspaper ads in several cities announcing that they had purchased sponsorship rights to the Liberty Bell, and it would subsequently be renamed the "Taco Liberty Bell." Millions of outraged people called the US Landmarks Commission in protest before the hoax was revealed, causing then-White House Press Secretary Mike [=McCurry=] to sarcastically (and in a surprisingly self-aware way for a bureaucrat) respond that Ford had also acquired sponsorship of the Lincoln Memorial, renaming it to the "Ford-Lincoln-Mercury Memorial."

[[folder:Anime & Manga]]
* ''Manga/AxisPowersHetalia'' usually has an event on the author's blog where one of the characters takes over the site for the day.
* In 2003, mahq.net made an April Fools' Day [[http://www.mahq.net/rants/prank.htm prank announcement]] of a ''GundamSEED'' sequel, which some websites in Japan apparently thought was a genuine one. And when ''GundamSeedDestiny'' was released, the uncanny similarities [[HilariousInHindsight just made it funnier.]]
** In addition April 1st is the site's anniversary, meaning they generally don't do April Fools' Day jokes. That, and it's admittedly [[ToughActToFollow kind of hard to top]] Grandiose Gundam.
* In 2010, promotion for the upcoming ''Manga/{{Gintama}}'' movie was changed so that [[http://community.livejournal.com/gintama/898276.html Shinpachi appeared to be the main focus]]. Worth it for Gintoki's expression in the cutaway panel alone.
* In 2012, Creator/AdultSwim brought CN's much loved {{Toonami}} block BackFromTheDead for one night only, with all new recorded lines from [[Creator/SteveBlum TOM 3]], airing episodes of nostalgic anime like ''Manga/OutlawStar'', ''Anime/TheBigO'', ''Anime/DragonBallZ'', and other shows that had previously aired on both Toonami and Adult Swim. This case is notable because fan reaction was so overwhelmingly positive and widespread that [[https://twitter.com/#!/adultswim/status/202866436597743616 Cartoon Network brought the block back for good a month later!]]
** For April Fools Day 2014, the fan site [[http://toonamifaithful.com/ ToonamiFaithful.com]] uploaded an [[http://toonamifaithful.com/exclusive-dragonball-z-is-returning-to-toonami/ article]] claiming that ''Anime/DragonBallZ'', one of Toonami's biggest {{Killer App}}s during its Cartoon Network years, would be returning uncut and in 16:9 HD... and would be taking up ''the entire lineup'', pushing every show currently airing off the block. The article, which was written to be as conspicuous as possible, even included fake quotes from Creator/{{FUNimation}} and Williams Street. The reaction was mixed, from those who took the joke in good spirits, to those who were pissed that it was just a joke, and to those who were convinced that it was actually true (to the point where some people on Twitter asked Jason [=DeMarco=] for confirmation). The joke itself was made ominously prophetic, however, when it was announced shortly after that Toonami would be airing the ''Cooler's Revenge'' movie, and ''even more so'' when, on that same night the movie aired, it was announced that the 2009 recut ''[[Anime/DragonBallKai Dragon Ball Z Kai]]'' would eventually be coming to Toonami.
* In 2012, Crunchyroll announced a new streaming app for UsefulNotes/GameBoy. The ''original'' [[http://www.crunchyroll.com/forumtopic-756509/april-fools-crunchyroll-app-for-gameboy Game Boy.]]
* In 2015, the guys behind ''LightNovel/ACertainMagicalIndex'' claimed that they would release a spin-off starring Accelerator's GenderFlip counterpart Yuriko Suzushina, who doesn't actually exist in-universe and is just an imaginary character.

[[folder:Comic Books]]
* In 2005, ''Magazine/{{Wizard}}'' magazine announced that GeoffJohns was working on a VertigoComics version of ''Comicbook/CaptainCarrotAndHisAmazingZooCrew'', in which the Crew was disbanded, Little Cheese was murdered by one of his teammates, and a new character called the Bald Eagle had to bring them all back together. Then Johns topped this by actually writing it into an issue of ''Comicbook/TeenTitans'' the following year.
** In later years ''Wizard'' had fake April Fools reports that PaulDini and Alex Ross were producing a graphic novel starring Zan and Jayna, the Wonder Twins from ''WesternAnimation/{{Superfriends}}'', and that Steve Niles, creator of ''ComicBook/ThirtyDaysOfNight'', was producing a horror comic staring cereal mascots Franken Berry, Boo Berry and Count Chocula.
* In 2009, the big news on the comics blogsphere was Johns again, now working on ''[[http://onceuponageek.com/2009/04/01/geoff-johns-and-ethan-van-sciver-talk-vibe-rebirth Vibe: Rebirth]]'' with Ethan Van Scriver. At last, one of the most iconic characters in the DC stable is brought back to glory!
** For those who don't follow DC, Johns has done "Rebirth" stories for Comicbook/GreenLantern (Hal Jordan) and Comicbook/TheFlash (Barry Allen). Vibe, a [[TotallyRadical painfully-eighties]] inner-city kid with the meta-human ability to produce sonic waves, often through breaking dance, was a, uh, "less prominent character".
* In 2010 TopShelfProductions released a cover for ''Comicbook/TheLeagueOfExtraordinaryGentlemen'' [[http://www.comicsalliance.com/2010/04/01/top-shelf-announces-league-of-extraordinary-gentlemen-1988/ 1988]], featuring among others [[Film/BackToTheFuture Doc Brown]] and [[Series/TheATeam Sergeant Bosco "B.A." Baracus]].

[[folder:Fan Works]]
* ''FanFic/{{Anthropology}}'' released [[http://www.fimfiction.net/story/18724/Truth-vs.-Fiction a fake Chapter 18]], which appeared to be about Lyra discovering the actual ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' cartoon show... [[FakeOutOpening before abruptly diving into]] CrackFic [[FanFic/GurrenJesus territory]].
-->'''Lyra:''' ''(after Bon-Bon is "revealed" to be a Soviet spy)'' This is such a plot twist.
* In 2013, ''Fanfic/JakeEnglishsMysteriousTheaterOfScientificRomanceFromTheYear3000'' had Caliborn review the first chapter of FanFic/DragonAgeTheCrownOfThorns.
* In 2010, ''KristophGavinAceAttorney'' did one of these, where [[TheDogWasTheMastermind a minor character is suddenly revealed to be the true killer]], and shoots the protagonist.
* The first FanFic/OnACrossAndArrow chapter released for ''FanFic/TheSweetieChroniclesFragments'', taking Sweetie Belle briefly through the worlds of ''Series/DoctorWho'', ''{{Series/House}}'' and ''{{WesternAnimation/Megamind}}''. [[http://www.fimfiction.net/story/2593/5/the-sweetie-chronicles-fragments/oaca-april-fools It's still available, by the way.]]
** In 2013, [[http://www.fimfiction.net/story/2593/12/the-sweetie-chronicles-fragments/the-immortal-game-april-fools-2013 another April Fools' Day chapter was released]], this one being the first FanFic/TheImmortalGame chapter--which is connected to the author's other fanfics on Website/FimfictionDotNet.
* The first released version of ''Videogame/SuperSmashPonies''. It shows the title screen, then a loading screen... loop ad infinitum.
** For April 1st, 2014, the dev team announced that progress on the game was ceased. The following day, a blog post was added claiming that no, the game was not dead and progress has not been ceased.
* The Facebook page for ''VideoGame/SuperSmashBrosCrusade'' posted a status update on April 1st, 2013 mentioning that a character named "Joe the Condor" would be part of the character roster in the following version of the game.
** On April 1st, 2014, another status update was posted mentioning that the game has been bought by {{Disney}} and that all characters would be replaced by Disney characters. (Well, Sora may become a DLC character, so that's a start.)
* [[https://www.youtube.com/watch?v=v-gL5nRz99o This]] video was released on April Fools 2014 on the [=McLeodGaming=] channel announcing the return of a 4th-party character from ''VideoGame/SuperSmashFlash'' into [=SSF2=].
* [[PlayingWithATrope Played with]] by the author of ''WebAnimation/TurnaboutStorm'':
-->''So this is the part where I would say Part 5 is canceled... and you all would be like all "OH NOEZ" and I would be like "APRIL FOOLZ", then you would be like "[[MemeticMutation obvious AFD joke is obvious]]" or "U got me lol". [[TeasingCreator But I think I've teased you enough]], so let's just pretend I did that :)''
* Similar to SSP, ''[[http://raycordlegends.com Raycord Legends]]'' released a demo on April 1st, 2015. [[https://pbs.twimg.com/media/CDB81riVIAAZ2WR.jpg This is the title screen of the game.]]
* Back when it was still being regularly updated, the authors of ''FanFic/SevenLittleKillers'' once announced they were abandoning the story on April 1st, waiting a ''very'' long time to reveal it was a joke. Not many of their huge fanbase really thought it was funny. More of a FunnyAneurysmMoment, now that it appears they have abandoned the fic for real.
* For April 1st 2013, a new chapter of ''FanFic/{{Pokeumans}}'' was released in which within a few paragraphs a giant monster appeared from nowhere [[HilarityEnsues and killed everyone in a ridiculous overblown fashion.]]
* FanFic/{{Xenophoolia}}, a collaboration between several different FanFic/{{Xenophilia}} authors was this, especially because the multi-chaptered tale bounced back and forth between the different authors' accounts. Released on April Fools' Day of 2014, the story focuses on how Lero Michealides from ;Xenophilia: Further Tales' takes a wild tour through TheMultiverse, culminating in him visiting the Lero Michealides from Fanfic/DividedRainbow.
* In 2015, the author of ''Fanfic/TheBridge'' released a long list of "spoilers". While some are plausible, the rest are ridiculous.
* In 2010, the fanfic ''[[http://www.fanfiction.net/s/5739114/29/Paradise_in_Death Paradise In Death]]'' rickrolled readers. In text form.
* On April 1st, 2015, ''Fanfic/MovieNightAtFreddys'' released a joke chapter which involved the characters of ''VideoGame/FiveNightsAtFreddys'' reenacting the opening number of ''Theater/LesMiserables''.

* In 2011, Creator/TheCriterionCollection announced that after years of releasing prestigious films on [=DVDs=], the next release would be the notorious BMovie ''Film/{{CHUD}}''.
** In 2012, they announced the same thing would be done for ''Film/KindergartenCop''.
* In 2013, Creator/{{Pixar}} launched a website to promote ''MonstersUniversity'' that resembled the website of real colleges. On April 1st of that year, the site appeared to have been hijacked and vandalized by rival college Fear Tech.

* In 2012, weeks after the final book for ''Star Wars: Fate of the Jedi'' was released, Suvudu published [[http://star-wars.suvudu.com/2012/04/post-star-wars-fate-of-the-jedi-news-and-exclusive-epilogue-by-timothy-zahn.html a fake epilogue by Timothy Zahn]], claiming [[spoiler:it was Luke's clone who survived the events of ''The Last Command'', not the real Luke]]. Also, there's a revelation that [[spoiler:Grand Admiral Thawn's master plan was to collect a complete set of clones, and almost all of the characters may or may not be clones]], marking the launch of an unending ''Star Wars'' series called [[spoiler:''Star Wars: The Clone Wars 2'']].
* ''Literature/TheHuntingOfTheSnark'' was first published on April 1, 1876.

[[folder:Live Action TV]]
* Creator/TheBBC's ''Panorama'' made [[http://news.bbc.co.uk/onthisday/hi/dates/stories/april/1/newsid_2819000/2819261.stm a show about "spaghetti trees,"]] leading to many viewers asking how they could grow their own.
* The BBC also produced a feature showing a recently discovered breed of penguins which flew to the jungle in the summer.
* Another famous incident on the sports show ''Grandstand'' involved a particularly hilarious FunnyBackgroundEvent: Watch it [[http://www.youtube.com/watch?v=R4fBrZj1uXM here]].
* A DiscoveryChannel program played perfectly straight, that proved that yes, in fact The Earth Really Is Flat.
* ''TheDrewCareyShow'' made a few April Fools' Day episodes in which there would be various oddities occurring in the otherwise typical episodes (snow falling on set, mispronunciation of names, the ultrasound baby in the Mohawk Productions VanityPlate meowing instead of giggling, etc...), [[BigLippedAlligatorMoment which are never brought up again]]. Creator/{{ABC}} made these into contests as to who could spot them all. The major plot points of those episodes have been brought up again, such as Mr. Wick's GroinAttack, so those at least are canon; when rerun, each error is pointed out ''Series/PopUpVideo''-style.
* Creator/{{GSN}} (Game Show Network) did a major host switch on April, 1, 2003 among its original programming. Marc Summers hosted ''{{Cram}}'', Todd Newton hosted ''Series/RussianRoulette'', Graham Elwood hosted ''[[Series/{{Whammy}} Whammy: The All-New Press Your Luck]]'', Mark L. Walberg hosted ''Series/FriendOrFoe'' and Lisa Kennedy Montgomery hosted ''Series/WinTuition''. The five hosts came together for a charity episode of ''{{Lingo}}'', which also had Todd Newton announcing (and Mark and Marc curb-stomping Graham and Kennedy 500-0).
** On the subject, even with each host switch, each show's original host would cameo at some point: Kennedy appeared briefly in ''Friend or Foe'', Summers was dressed up as a prop for part of ''[=WinTuition=]'', Elwood filled in for Pickwick in ''Cram'' (DisguisedInDrag, no less), Wahlberg was in the ''Russian Roulette'' audience (along with Kennedy and the Whammy), and Newton showed up for some Double Whammies in ''Whammy!''
* Speaking of game shows, ''Series/WheelOfFortune'' and ''Series/{{Jeopardy}}'' both partake in this:
** 1997: ''Jeopardy!'' host Creator/AlexTrebek and ''Wheel'' host Pat Sajak traded places. Pat and co-host Vanna White also played ''Wheel'' that day, with Pat's wife, Lesly, at the puzzle board. The flip-flop was {{lampshaded}} heavily on both shows: ''Jeopardy!'' had ''Wheel''-themed categories in the first round (such as "Buy a Vowel" and "Before & After," which later became a recurring category on ''Jeopardy!'' itself), and "fool"-themed categories in the second, and a Final ''Jeopardy!'' category of "Trinidadian Amateur Ichthyologists." ''Wheel'' had several gag puzzles, including TRADING PLACES as the BonusRound answer.
** 2008: Alex wore a fake mustache (he had shaved off his trademark mustache by this point), and Pat tricked Vanna into believing he was bald by wearing a real wig over a bald wig.
** 2010: ''Wheel'' made 10 things wrong with the show. They invited viewers to print out a worksheet from their website, and write down what they thought were the correct answers. Some were obvious (i.e. the Bankrupt wedges having "Bankrut", the Polish translation of that word), some weren't (Pat wearing a stud earring in the second round), and an eleventh wasn't even pointed out (rodeo footage in the opening montage of Hawaiian activities corresponding to the rest of the week's Hawaii theme). ''Jeopardy!'' spliced in different hosts for Alex Trebek on the same day. Alex still read the clues, but Pat Sajak walked out at the top of the show, Neil Patrick Harris was spliced in during the first round, Jeff Probst (who once hosted ''Rock & Roll Jeopardy!'' before his ''Series/{{Survivor}}'' fame) during the second round, and a clip from ''SaturdayNightLive's'' ''Celebrity Jeopardy!'' sketches featuring Will Ferrell parodying Alex Trebek. There was also an "April Fool!" category concerning joke articles published during the month of April (such as the ''Veterinary Record'''s "Brunus edwardii" article).
** 2011: Every puzzle on ''Wheel'' (except the BonusRound) had the word "fool" in it. Amazingly, the contestants never caught on; you'd think by the third round, they would've been calling L and F, then buying an O.
* ''Series/ThePriceIsRight'' has a long history of making gag prize Showcases with obviously silly prizes (e.g. egg beaters and paper plates, "six new cars" that turn out to be Matchbox cars, or even an acute case of athlete's foot as a prize). On another episode, the door that host Bob Barker normally walked through revealed a sign that said "April Fools!" before Bob walked onstage through the audience.
** Drew Carey, after taking over as host on ''Price'', has made several April Fool's gags on each April 1 episode. Except for 2011, he brought in Kathy Kinney, who reprised her role of Mimi Bobeck from ''The Drew Carey Show''. He also does several funny gags throughout — things like playing the ''MatchGame'' music during the credits, having everyone wear nametags that say "Pat", having random sound effects play during the Showcase Showdown instead of the normal ones, etc.
** For 2011, the gag was that the 10,000th...''some''thing was going to happen today, so it was an important episode. Too bad so many things went wrong, from pieces of the set falling apart or malfunctioning, to announcer George Gray getting hit by a tennis ball launcher. And the 10,000th ''thing'' [[TheUnreveal didn't even happen]]. "Maybe tomorrow," says Carey...only April 1, 2011 fell on a ''Friday''.
** For 2013 (2012 having April 1 on a weekend), the models took over the hosting and announcing duties, and made Drew and George model the prizes.
** 2014's April Fools episode toned down the silliness but continued to insert some running gags. The most notable thing about the episode was the visible absence of all the regular cast. Creator/CraigFerguson was host for the day, though Drew Carey made cameos on [=TVs=] from the set of ''TheLateLateShow''. Shadoe Stevens filled in at the announcer's booth, but George Gray still announced on occasion through Geoff Peterson that appeared here and there throughout the show. And no models appeared on stage except Secretariat.
** for 2015 they had a special guest host for the first pricing game: [[spoiler: BOB BARKER!]]
* Cranked UpToEleven as a prank on Tom Bergeron for ''Series/TheHollywoodSquares'' episode taped to air on April Fool's Day 2003. At one point the male and female contestants were engaged in a heated argument, after which the male contestant made the female contestant break down in tears. Bergeron, who had a deer-in-the-headlights look (but, according to his book, wasn't going to stop no matter what), comforted the "poor woman" as he sent the show to commercial (unbeknownst to him, the camera was still running). At the end of the episode, giggling executive producer Henry Winkler (who was also filling in as announcer at the time) said over the intercom, "Hey Tom...April Fool's." Apparently, Bergeron hadn't realized the airdate of the show...until then. The "contestants" were in fact trained actors.
** In the John Davidson era, a similar joke was played in 1987. Both contestants got into a fight after Miss Circle claimed Mister X got a quick look at John's card to successfully get a square. It ended with [[spoiler: Miss Circle pushing Mister X off the podium]], followed by the audience shouting "April Fools, John!" in unison. It turns out [[spoiler: both contestants were stunt people]]. The show continued afterward with real contestants.
*** Luckily, they didn't go to extremes in 1988: John Davidson was center square for that show while Joan Rivers hosted.
* Going back to the 90s, the current-events trivia show ''Series/TheChallengers'' played a joke on the April 1, 1991 show, puzzling the contestants and host DickClark with very obscure subjects before revealing the joke on the video wall. The contestants rolled with the gag while Clark told Judge Gary Johnson (who was behind the gag), "Go to your room!" The game then resumed with the real categories.
* Actually a pre-April Fools Joke from the nighttime version of ''Series/TheDatingGame'' from 1969--After [[CharliesAngels Farrah Fawcett]] selects her date, [[https://www.youtube.com/watch?v=gPLW7Q1X6CU#t=4m55s the three bachelors get into a brawl.]] [[spoiler:The three bachelors are actually stuntmen.]]
* The UsefulNotes/{{Seattle}}-based sketch comedy ''Series/AlmostLive'' did a fake broadcast announcing that local landmark the Space Needle had fallen over. Their hosting station ended up having to issue a formal apology.
* ''Franchise/PowerRangers''
** In 2011, the official Facebook pace announced that the Mauve Ranger would join "Series/PowerRangersSamurai".
*** In 2012, the official Facebook page announced [[http://powerrangers.wikia.com/wiki/Morphume Morphume]] collection, a set of perfume based on ''Series/PowerRangersSamurai''.
*** In 2013, they announced a Power Rangers SMART PHONE, based on the Gosei Morpher.
*** In 2014, they announced a line of fine jewelry based on Mighty Morphin' Power Rangers.
** In 2012 Ranger Crew reported that ''Series/KaizokuSentaiGokaiger'' iwould be adapted as [[http://morphinlegacy.com/2012/04/rangercrews-awesome-april-fools-joke.html Mighty Morphin' Pirate Rangers]] and that specific past characters were confirmed to be returning such as [[Series/PowerRangersTurbo Justin]]. This report was reported on [=JEFusion=] as well leading some to believe, and insist when others told them otherwise, it was real. In real life, ''Gokaiger'' would be adapted as ''[[Series/PowerRangersMegaforce Power Rangers Super Megaforce]]'' in 2013.
*** In 2014 Rangercrew posted that Saban had revealed Power Rangers Energy Chasers an adaptation of Go-busters to air on Vortexx presumedly to air along side the previously announced Dino Charge on Nickelodeon, Naturally people were bummed since Go-busters was previously announced to be skipped over a proper adaptation and be used to a certain degree in the Kyoryuger adaptation, Dino Charge.
* The gay-themed channel Creator/{{LOGO}} had a whole ad campaign about ''The A-List: Amish Country'' (''The A-List'' was a short-lived ''Real Housewives''-style reality series featuring gay men[[note]]For anyone not familiar, the Amish are a conservative religious society who shun tech and live off the land and the Bible. In their society, homosexuality is taboo.[[/note]]). Granted, it fooled no-one and was more intended as a parody of the series.

* ''Discover'' magazine has published a number of notorious articles featuring absurd scientific discoveries, such as a macroscopic subatomic particle improbably named the "bigon".
** The most infamous of these articles is the [[http://en.wikipedia.org/wiki/Hotheaded_Naked_Ice_Borer Hotheaded Naked Ice Borer]], a fictional Arctic animal created for the holiday in 1995. The critter was briefly picked up as an actual news item by at least one other source, and there are anecdotes of inquiries by zookeepers looking for a specimen! Discover claims it has received more mail about this one article than any other it has ever published.
** Another dealt with a native culture that had [[BambooTechnology created primitive "computers"]] by tying multiple knots in ropes using a system they had devised. A little common sense applied showed that this was not only silly, but a {{pun}} - they were ''[[DontExplainTheJoke knot computers]]''.
*** For further humour, this was at one time seriously proposed (fringe) explanation for the quipu.
* ''Magazine/SportsIllustrated'' ran a story in its April 1, 1985 issue called "[[http://www.si.com/mlb/2014/10/15/curious-case-sidd-finch The Curious Case of Sidd Finch]]". The article, written by George Plimpton, ostensibly profiled a phenomenal and unknown New York Mets pitching prospect. Mr. Finch (it was claimed) grew up in an English orphanage, went to Harvard, studied yoga in Tibet, played the French horn, and could throw a baseball up to 168 MPH. The magazine even teased readers with a FunWithAcronyms subhead to the piece:
--> "'''H'''e's '''a''' '''p'''itcher, '''p'''art '''y'''ogi '''a'''nd '''p'''art '''r'''ecluse. '''I'''mpressively '''l'''iberalted '''f'''rom '''o'''ur '''o'''pulent '''l'''ifestyle, '''S'''idd's '''d'''eciding '''a'''bout '''y'''oga—and his future in baseball."
** The bogus story was nonetheless taken at face value by numerous Met fans, sports reporters, and rival general managers.''SI'' continued the gag the following week with an article announcing Finch's "retirement" from baseball, then finally let the cat out of the bag in the April 15 issue.
* ''Magazine/DoctorWhoMagazine'' has had several, including a claim that the ''Series/DoctorWho'' story [[Recap/DoctorWhoS8E5TheDaemons "The Daemons"]] was meant to be six episodes long, not five, and that the sixth episode had been discovered (much later, fan historians such as TatWood were still having to explain that this wasn't true).
* ''Magazine/NintendoPower'' does this a lot:
** 1997 ran phony newspaper clippings, one of them saying that the Headless Snowman from ''VideoGame/SuperMario64'' was getting his own game instead of Luigi.
** 1999 had an article featuring Pikachu from Franchise/{{Pokemon}} as a [=Y2K=] expert. However, his advice was completely useless since all he ever spoke was the iconic PokemonSpeak. The authors eventually turn to BillGates himself...who unfortunately also speaks in Pokémon Speak.
** 2001 discussed "Warp Pipe Technology", a fake {{Defictionalization}} of the warp pipes of ''SuperMarioBros.'' fame. At least two readers were fooled and wrote in to ask about the technology; their response:
--->How can we put this gently? The test subject, Dr. Dru Wiliamskini, has a new nickname: "Steaming Puddle of Goo." Better luck next year!
** There was also the infamous Zelda April Fool's joke, showing fake screenshots of Link holding the Triforce. This only further fueled rumors of secret ways to get the Triforce, even after Nintendo repeatedly explained it wasn't possible.
* ''[=GamePro=]'' had an annual April feature called "[=LamePro=]", which mostly featured crude reimaginings of the hot games of the day, along with some mashups like "Series/{{Barney and|Friends}} [[BeavisAndButthead Butthead]]" and "StreetFighter [[TheLittleRascals Alfalfa]]".
** Lamepro had a review of the ''Comicbook/{{Daredevil}}'' console game, and exclusive screenshots of a black screen - and the multiplayer mode (a black screen divided into four black screens.)
* ''Magazine/ElectronicGamingMonthly'' was so good at this, they ended up creating [[UrbanLegendOfZelda Urban Legends Of Zelda]] out of most of them. They are described in detail in the aforementioned article, but for the sake of summarization:
** 1991: [[Franchise/{{Castlevania}} Simon Belmont]] in ''[[VideoGame/TeenageMutantNinjaTurtlesTheArcadeGame Teenage Mutant Ninja Turtles II: The Arcade Game]]''.
** 1992: Sheng Long in ''VideoGame/StreetFighterII'' (Lead to the creation of Akuma, and later, [[VideoGame/StreetFighterIV Gouken]]).
** 1993: Four fake games for the UsefulNotes/AtariJaguar.
** 1994: ''[[RougeAnglesOfSatin Streeets]] [[StreetsOfRage of Rage 3]]'' ([[ParodyRetcon allegedly]])
** 1995: Creator/{{Nintendo}} publishing a ''Franchise/SonicTheHedgehog'' game. (this became HilariousInHindsight when Nintendo was handed the Japanese publishing rights for ''VideoGame/MarioAndSonicAtTheOlympicGames'')
** 1997: Sheng Long in ''VideoGame/StreetFighterIII''.
** 1998: [[DummiedOut "All Bonds" cheat]] in ''[[VideoGame/GoldenEye1997 GoldenEye 007]]''.
** 1999: The [[XtremeKoolLetterz GameShortz]], which was just boxer shorts with PlayStation controllers attached.
** 2000: The return of the UsefulNotes/{{Intellivision}}.
** 2001: Creator/{{Sega}} selling Sega Neptunes.
** 2002: Sonic and Tails in ''VideoGame/SuperSmashBros. Melee'' (this became HilariousInHindsight when Sonic made it into ''Brawl'').

** 2004: ''Film/LordOfTheRings'' [[WackyRacing racing games]].

** 2010: ''VideoGame/CallOfDuty:'' set in UsefulNotes/TheAmericanRevolution.
* ''Game Informer'' has a section in every April issue called "Game Infarcer", complete with a faux cover and mini-articles poking fun at various aspects of the gaming world. In each May issue, GI publishes a few choice letters from people who believed the jokes to be real, despite the fact that every Game Infarcer page has "PARODY" in capital letters at the bottom. Interestingly enough, in 2010, most of the objections were not to the articles, but fake Editor-in-Chief Darth Clark's declaration that his game reviews had surpassed actual games as an art form.
* In 2008, ''Hot Rod'' [[http://www.hotrod.com/featuredvehicles/hrdp_0804_amc_concept_cars/index.html published an article]] proclaiming the revival of American Motors (bought by Chrysler in 1987). The article contained detailed information and drawings of forthcoming models including the AMX, Matador, Ambassador, Pacer, and Gremlin. It was later revealed to be an April Fools' Day joke.
* ''Road & Track'' usually prints a review of something other than a car, but a mode of transportation none the less.
* In their April 2012 issue, ''Car and Driver'' listed 25 cars that would be released within the next few years. Most of them were real, except for [[http://www.caranddriver.com/features/2015-chrysler-td-by-maserati-future-cars the Chrysler TD By Maserati]].
* ''MacAddict'' (now ''Mac|Life''), upon its first April Fools' Day in 1997, ran a lot of jokes. Among them were a letter from the editor explaining that the magazine would be shifting its focus to Windows, and an ''Onion''-esque fake news section.
* The April 1988 issue of ''Your Sinclair'' included a glowing review of a fictional lawn-mowing SimulationGame. ''Advanced Lawnmowing Simulator'' was inevitably [[{{Defictionalization}} defictionalized]].
* ''The One Magazine'''s April 1990 issue contained a [[http://amiga.lychesis.net/knowledge/CyberAssault556.html preview]] of a supposed upcoming game, ''Cyber Assault 556'', a highly complex WideOpenSandbox space sim game (complete with fake screenshots).
* The Polish gaming magazine ''Reset'' had a different kind of joke in every April issue (except for April 1997, because that was their first issue.) In 1998, the entire magazine layout was turned 90 degrees, and there was a enthusiastic review of a fictional game ''666'', a supposedly highly complex WideOpenSandbox game produced by the Polish company [[SdrawkcabAlias Teser Interactive]]. There was also a humorous hardware review of a... glass, and a spurious article about Bill Gates converting to Buddhism.
* The Polish gaming magazine ''CD-Action'' pulled off subtle jokes sometimes. For instance, in the April 1999 issue, they claimed that in ''Franchise/TombRaider 4'' Lara Croft would have a second pair of breasts added to her back, and that IDSoftware was preparing to release ''VideoGame/{{Doom}} 2000'' that would run on the Unreal engine.

[[folder: Music]]
* In April Fools Day 2015, {{Music/Brentalfloss}} released the song everyone has been requesting for over 7 years... the overworld theme of ''VideoGame/SuperMarioBros1'' with lyrics. There's just one catch though... the lyrics he sings are in Japanese. (''Accurate'' Japanese, mind you, Brent had a translator working on it.) Like Brent himself said, BeCarefulWhatYouWishFor.

[[folder: Newspaper Comics]]
* In 1997, several comic artists swapped strips, producing such oddities as a ''ComicStrip/{{Dilbert}}'' comic in the style of ''FamilyCircus'' (which ''ComicStrip/{{Dilbert}}'' author Scott Adams described as one of the signs of the Apocalypse).
** Kevin Fagan was unable to find another cartoonist to trade ''Drabble'' with, so he [[StylisticSuck drew it with his left hand]].
* In 2005, several comics including ''{{Foxtrot}}'', ''ComicStrip/PearlsBeforeSwine'', and ''GetFuzzy'', did identical comics where one character plays with a Ouija Board and uses it as an excuse to hit another, eliciting the response "Somehow I imagined the afterlife to be a more peaceful place."

[[folder:Tabletop Games]]
* ''Magazine/{{Dragon}} Magazine'', the house organ for TabletopGame/DungeonsAndDragons, would usually dedicate their April issues to sillier fare. For example:
** One issue had a series of mixed up spells like 'Find Terrain' for which the 'somatic' component was to fall forward, at which you have just 'found the terrain'.
** Another issue had on its cover a chubby warrior holding flowers up to a beholder which had on makeup and flowers...[[StealthPun "Beauty is in the eye of the...Oh nevermind!"]]
*** Another time, they packaged the April Fools material in one section of the magazine, with a cover page that parodied the heroes-steal-giant-demon-statue-eyes cover of the 1E ''Player's Handbook''. Exact same scene, except the demonic statue and gem thieves are all teddy bears.
** Shortly after 3.5 introduced a Flaws mechanic, they did flaws for Commoners (the least powerful of the NPC classes); one of the flaws, called "You Got Chickens", had the character suffering a 50% chance of retrieving a chicken any time they tried to draw something from their pack. This was promptly exploited on the Character Optimization board.
** The parody songs of "Bard On The Run".
* Creator/WhiteWolf and its SpiritualSuccessor Onyx Path Publishing are in the habit of releasing a joke supplement on April Fools' Day.
** They kicked off in 2008 with the release of an excerpt from a pitch for ''Shadows of Iceland''.
** In 2009 they released the ''Scroll of Swallowed Darkness'', an incomplete, sex-themed supplement for ''TabletopGame/{{Exalted}}''. In 2012, they released errata for it.
** 2010 saw the release of ''Dudes of Legend'', a very NSFW Take That-filled [[TabletopGame/NewWorldOfDarkness nWOD]] supplement with rules for, among other things, [[Literature/{{Twilight}} using glitter to let vampires go out in the sun]], and gaining superpowers from homoeroticism.
** For 2011, they released ''Paths of Storytelling: Vampire'', a ChooseYourOwnAdventure-style piece for ''TabletopGame/VampireTheMasquerade''.
** In 2013, they released ''TabletopGame/{{Scion}}: Extras'', a collection of [[OddJobGods (perhaps justifiably) obscure Gods]] and their Scions.
** 2014's release was a set of [=nWOD=] Overly Narrow Condition cards, for use when [=PCs=] ran into highly unlikely situations.
** In 2015, they announced that, inspired by the popularity of the Kickstarter for historical [=nWOD=] supplement ''Dark Eras'', they'd be transplanting all TabletopGame/OldWorldOfDarkness and TabletopGame/NewWorldOfDarkness gamelines to the nineteenth century, at the height of Gothic literature's popularity, in order to add Historical Angst (TM) and gothness. As an indication of where this would be going, they released [=nWOD=] supplement ''Gothic Icons'', statting up characters from Gothic literature who represented {{goth}} archetypes.
* Palladium Books has a combination fanzine/sourcebook for ''{{Rifts}}'' and other Palladium titles called ''The Rifter''. They created an April Fool's Issue called ''The Rifter 9 1/2'', which was full of ridiculous characters, alternate rules, and other silly content. A RunningGag throughout the issue was that Palladium Books had been sold to the fictional Percy Ferkleberger, who began effecting massive changes in ''{{Rifts}}''. The most notable example was the new rules for "Giga-Damage," which was a massive in-joke regarding the game's love of MoreDakka, the fact that ''{{Rifts}}'' tends to attract {{Munchkin}}s, and PowerCreepPowerSeep in general. Most amusingly, the Rifter 9 1/2 was made primarily as an April Fool's Joke on The Rifter's editor, who had heard nothing about it until the first copies arrived at the warehouse.
* Catalyst Games Labs, the current publishers of {{TabletopGame/BattleTech}} and {{Shadowrun}}, celebrates April Fools' by releasing gag products which are nonetheless playable. Considering that they're also ''free'' products, it's a pretty good deal if you can take the joke.
** The 2012 releases were Taiwan-themed scenario-packs. The TabletopGame/BattleTech releases included a "Third (Star) League Turning Points" scenario-pack (set two centuries beyond the current in-universe date, complete with units and weapons advanced beyond even Clan technology).
** The 2013 TabletopGame/BattleTech release is an 'Experimental Technical Readout'. It's titled ''XTRO:1945'', and details a range of units from ''World War 2'', complete with the gear they need to fight a [[HumongousMecha BattleMech]]. They ''are'' playable units, and incredibly deadly to each other. Against '''Mechs'' is another matter.
* ''TabletopGame/YuGiOh'': Kevin Tewart, a member of Upper Deck Entertainment, sent a letter claiming that the card [[http://yugioh.wikia.com/wiki/Card_Trooper Card Trooper]] had been misprinted, making its effect vastly different. The first letter of each paragraph spelled out "APRIL FOOLS".

[[http://biosector01.com/wiki/index.php?title=Main_Page Bionicle Sector 01]], the {{Bionicle}} [[TheWikiRule Wiki]], Lost quite a few of their images and pages a while ago, but managed to find some replacement images of the Toa Nuva, Mata Nui, and Makuta Teridax, thanks to a certain [[WesternAnimation/MyLittlePonyFriendshipIsMagic Derpy Hooves]]...

[[folder:Video Games]]
* ''VideoGame/{{Roblox}}'' pulled off several, but in 2014, they said that they would ''change the game so that your character is a '''cat.'''''
** This joke ''alone'' [[TheyChangedItNowItSucks enraged fans of the game]], which some said they'd ''quit'' if this was true.
*** The admins pulled off a scheme before in 2013, which was changing forum titles to [[MemeticMutation memes.]]
*** Someone did an [[ThereIsNoKillLikeOverkill extreme one]] in 2012, where he took over admin's accounts, unadmined them, and said several unusual things.
* Creator/{{Nintendo}} joins in on the fun, too.
** They had forced players to update before accessing the eShop, which after updating, had the eShop's homepage be [[HostileShowTakeover centered around villains, with the subtitle "PROCEED WITH CAUTION! VILLAINS HAVE TAKEN OVER THE SHOP" slapped on the first image]], which is an image of [[Franchise/SuperMarioBros Bowser.]]
* IGN:
** 2008: In possibly one of the most elaborate April Fools' Day schemes ever, the site spent six months filming the trailer for a live action ''Zelda'' film. [[http://movies.ign.com/dor/articles/863515/legend-of-zelda-movie-trailer/videos/legendofzelda_filmtrailer_040108.html The trailer]] was hit or miss with the fans; some were ecstatic that the movie was being made, others were horrified at the idea. In any case, an impressive amount of detail went into the making, complete with CGI monsters, music taken from the games, and a complex storyline expressed in three short minutes of filming. The only clue to its status as a hoax was the purported release date for the actual movie -- April 1, 2009. At one minute after midnight on April 2, 2008, the site admitted it was a fake, and released their making-of featurette, which is longer than the trailer itself.
** 2009: They announced [[http://www.youtube.com/watch?v=Ef7kyNVU--c&feature=iv&annotation_id=annotation_280884 the release]] of a "hardcore" expansion of ''SuperSmashBrosBrawl'' that apparently differed little from the regular version except for the addition of decapitation and [[BloodierAndGorier gratuitous blood and gore]].
** 2010: [[http://www.youtube.com/watch?v=_4DHllroiqM Another fake movie trailer]], this time being ''Franchise/{{Halo}}''... [[spoiler:''reimagined as a UsefulNotes/{{Bollywood}} epic.'']] [[EarWorm FINISH THE FIGHT!]]
** 2011: instead of focusing on video games, IGN parodied ''Literature/HarryPotter'' and the DarkerAndEdgier milieu of cable television with a trailer for a fake TV show called ''[[http://www.ign.com/videos/2011/04/01/harry-potter-the-aurors-tv-show-trailer The Aurors]]'', made by ''Series/TheShield'''s Shawn Ryan and airing on FX. It was also to come with [[http://ps3.ign.com/articles/115/1159024p1.html an M-rated video game adaptation]].
** 2012 had [[https://www.youtube.com/watch?v=qOqHUa2LfNY a trailer]] for a {{Saturday morning|Cartoon}} BandToon [[AnimatedAdaptation adaptation]] of ''Franchise/MassEffect'', animated by HarryPartridge. "[[AutobotsRockOut Mass Effect, tune up!]]"
** 2013: they mocked Apple's products with the announcement of the [[http://www.ign.com/videos/2013/04/01/apple-introducing-iplay-game-console iPlay]] video game console.
** 2014: they released a fake trailer for [[Franchise/{{Transformers}} Optimus Prime]] DLC for the game ''VideoGame/{{Titanfall}}'', announcing said DLC to be available that very day. The fake trailer even contains a slight joke related to the [[Film/{{Transformers}} Bayformers]] movies by joking that said DLC would come with a new LinkinPark song entitled "Prime Time."
** 2015: A fake teaser trailer for a reboot of ''Film/BackToTheFuture'', done InTheStyleOf ''Film/TheFastAndTheFurious'', titled "Fast to the Future," complete with Vin Diesel and car drifting. [[https://www.youtube.com/watch?v=eLazRt8s8Wc See it here]].
* On April 1st 2012, ''Half-Life 3'' was spotted in the Steam store to not only be real, but on sale. A drawing of Valve founder Game Newell sporting a troll face. Most people wrote it off as Valve trolling the fan base and was widely reported that Valve was responsible. However it was later revealed that the store front was fake and that someone had went to the trouble of recreating it which was entirely functional and would take you to the real store when you clicked on real items. The media was floored that they overlooked the extra ''p'' in the URL which was [[http://store.steamppowered.com/ www.store.steam''p''powered.com]]
* Creator/BlizzardEntertainment has a tradition of April Fool's jokes which runs back at least to the development of ''VideoGame/WarcraftIII'', when they famously announced a race of panda-people as the fourth playable faction ([[HilariousInHindsight who eventually become a playable race in World of Warcraft]]). The jokes have been getting bigger every year:
** 2006: They announced the Two-headed Ogre. The ridiculously complex rules for playing such a creature (you had to play with a second person on a second account, randomly assigned) made it obvious it was a joke. In a slight subversion, they also announced a new neutral hero, the Goblin Tinker, for ''VideoGame/WarcraftIII'' on the same day that was not a joke. They tried to make it seem like either of the two could be real but it was fairly obvious.
** 2007: They announced Burgercraft: A chain of fast food restaurants that would serve Blizzard gamed themed food. They also announced the new Alliance race would be the Wisp, the weakest member of the Night Elf army, who could only attack by self-detonating. Finally, a "fired" employee "leaked" the [[http://www.wowpedia.org/Patch_1.11_%28Evil_Patch_Notes%29 next patch notes]], a list of facetious changes ranging from game breaking (Druids may only shapeshift outside of dungeons) to absurd (Hunter pets have a small chance to attack their owner when hungry) and outright insane (Paladins turn into bears) or literally pointless (being friendly via emotes to your demon slaves make them last longer, while the same update removed the warlock's ability to USE said emotes).
** 2008: Due to Blizzard's parent company purchasing Activision and changing its name from Vivendi to "Activision Blizzard", Blizzard announced a "second prestige" class: the Bard, which required you to play ''VideoGame/GuitarHero'' while playing ''World of Warcraft''. Also, poking fun at Sony's attempt to turn their MMO ''VideoGame/{{Everquest}}'' into a ''VideoGame/{{Warcraft}}'' style RTS, Blizzard announced that they were releasing "WoW: Heroes of Azeroth", an RTS prequal to World of Warcraft. It was ''Warcraft III'', and also served to poke fun at WoW players who were [[AdaptationDisplacement unaware of the previous games and lore]]. There was also the announcement of the "Tauren Moorines" for VideoGame/StarcraftII.
** 2009: Blizzard announced a dance battle system complete with trailer. The controls were said to work like riding a vehicle in ''Wrath of the Lich King''. For ''VideoGame/StarcraftII'', there was the announcement of Terratron, a {{Humongous|Mecha}} CombiningMecha made out of Terran buildings. For ''VideoGame/DiabloIII'', the Archivist was announced as a new class, having the character play a Deckard Cain-like old geezer whose dialogues are senile rantings. And on the UK ''World of Warcraft'' site, they announced a "Pimp My Mount" feature, which allows players to add ridiculous customizations to their mounts a la ''Series/PimpMyRide''. Additionally, every post made of the World of Warcraft forums that day was peppered with random roleplaying lines.
** 2010: Blizzard announced a new character rating for ''VideoGame/WorldOfWarcraft'' called the [[FunWithAcronyms Equipment Potency EquivalencE Number]] a vertical bar on your character that [[DoesThisRemindYouOfAnything grows]] as their gear improves (a TakeThat at players who rely too much on gear ratings to determine their worth), and the Battle.net Neural Interface which [[AndIMustScream permanently]] immerses the player in full VR and [[SuspiciouslySpecificDenial hopefully doesn't cause any permanent brain damage]]. And the [=WoW=] Armory character feeds had all boss kills changed to " Cheesed Boss" and all loot changed to " {{Ninja|Looting}}ed [Item]". Blizzard also introduced the new Battle.net matchmaker, a dating site where players would find romance in the form of "Someone to pwn noobs with." They also announced ''VideoGame/DiabloIII'' blankets and pillows and a Deckard Cain GPS voice pack to go with it.
** 2011: Blizzard announces Crabby, an expy of [[StopHelpingMe Microsoft's Clippy]], to assist on the forums and in-game for ''VideoGame/WorldOfWarcraft''. For ''VideoGame/StarcraftII,'' [[http://us.blizzard.com/en-us/games/console/ Blizzard makes a return to consoles,]] with peculiar motion-sensor tech. In addition to this, there are spoof patch notes for [[http://us.battle.net/sc2/en/forum/topic/2325614706 SC2]] and [[http://us.battle.net/wow/en/forum/topic/2325684862 WoW]], which serve as playful {{take that}}s to player complaints concerning both game balance ("Fixed a bug where Terran players were able to lose a game.") and aesthetic concerns (Every class with fire-based abilities gets green fire - except Warlocks).
** 2012: Blizzard will evidently be producing: [[http://us.blizzard.com/en-us/games/blizzkidzz/ Educational games for children]] such as "Zergling Teaches Typing" and [[VideoGame/TheOregonTrail "The Westfall Trail"]]; [[http://us.blizzard.com/en-us/games/supplydepot/ A mobile game]], "Supply Depot 2: [[VideoGame/HaloCombatEvolved Combat Elevated]]", about the exciting Starcraft metagame of raising and lowering Terran supply depots, with features such as [[VideoGame/MassEffect3 color-coded endings]] and [[VideoGame/TeamFortress2 lots of unlockable hats]]; [[http://us.blizzard.com/en-us/games/zergotchi/ Plastic toys]] to replace the authenticator, called [[{{Tamagotchi}} Zergotchi]], who grow and require periodic feeding to continue supplying authentication codes; A line of [[http://us.blizzard.com/en-us/news/?d=2012-4#312334 teen-oriented literature]] set in Blizzard universes and [[TakeThat inspired]] by ''Literature/TheTwilightSaga'', ''Literature/TheHungerGames'', et cetera; For the past several months they had been accused of dumbing down [=WoW=] with concepts from ''Franchise/{{Pokemon}}'' and ''VideoGame/FarmVille''. Also, Crabby returned with randomly generated hats.
** 2013: The ''VideoGame/StarcraftII'' situation report announced the return of the Warhound, a unit removed from the [=HotS=] beta for being pretty much identical to the marauder, to the lineup of their favorite race (Terran) based solely on the fact that the Terran player might have won the world championships with them. However, this left their favorite race (Zerg) at a disadvantage, so the Warhound was also added to the Zerg lineup. Finally, realizing that their favorite race (Protoss) were getting the short end of the stick, they also gave them the ability to build the Warhound in order to keep Protoss players from whining about it on the forums.
*** Crabby also returned to the Warcraft site, though still linked to last year's jokes.
* The 1998 [[http://everything2.com/title/TextFire Textfire Hoax]] produced a collection of playable text adventure demos (including ''Coma! An Interactive Action Thriller'' and ''Literature/FlowersForAlgernon'' and "Operation" adaptations) that represented the ostensible catalog of a commercial InteractiveFiction studio.
* Steam once did an April Fools' Day gag by releasing fake patch notes for ''VideoGame/{{Counter-Strike}}: Source'' that started with features such as "cost of sniper rifle reduced by 50%", "de_dust map removed" and "jumping now increases travel speed by 50%" and got progressively more ridiculous.
* [[http://bulbapedia.bulbagarden.net/wiki/April_Fool%27s_Day_2005 Many]] [[http://bulbapedia.bulbagarden.net/wiki/April_Fool%27s_Day_2006 people]] [[http://bulbapedia.bulbagarden.net/wiki/April_Fool%27s_Day_2007 celebrate]] [[http://bulbapedia.bulbagarden.net/wiki/April_Fool%27s_Day_2008 April]] [[http://bulbapedia.bulbagarden.net/wiki/April_Fool%27s_Day_2009 Fool's]] [[http://bulbapedia.bulbagarden.net/wiki/April_Fool%27s_Day_2010 in]] a funny and aggravating fashion in the ''Franchise/{{Pokemon}}'' fandom. Including the ''creators'' (Gamefreak).
** Now Serebii is claiming they don't like misleading the public, undoubtedly setup for THEIR jokes.
*** Probably the best one was releasing the rest of the English ''Diamond and Pearl'' data in one fell swoop after trickling it out bit by bit. Making us think it was fake was the joke in itself: The names were real.
** Now take another look at those "new Pokémon" from 2005. [[HilariousInHindsight As of Generation IV, there really]] ''[[HilariousInHindsight is]]'' [[HilariousInHindsight a pre-evolution of Chansey, and also a Pokémon that looks a lot like "Korechu" (Shinx).]] April Fools' Day joke, or stealth preview? (And remember, the fabled "Pikablu" turned out to be Marill, so...)
** For 2011, Bulbagarden changes its name to "Fushigarden" (Fushigidane, the Japanese name for Bulbasaur) and acts like it was 1998, when Pokémon was still young.
* The day before April Fools' Day 2009, the developers of the ''Franchise/SuperMarioBros'' fangame ''VideoGame/MushroomKingdomFusion'' released [[http://www.youtube.com/watch?v=7wwTWidX9PI this video]] showing gameplay of a "new character": Mickey Mouse.
* The team behind ''Mushroom Kingdom Fusion's'' sister project ''VideoGames/SuperMarioFusionRevival'' also made a joke with their game. In 2013, the development team posted [[http://www.youtube.com/watch?v=Y1-FfXmEVYw a video]] portraying Bowser as a PowerUpMount, claiming that they were scrapping the Bowser Rampage system due to the trouble of designing fun and interesting levels. The day after it was posted, the team revealed that the Bowser Mount was the original concept for having Bowser playable, and the video was recorded using an earlier build of the game.
* Harmonix appears to release ridiculously silly (and not at all rock-like) songs for ''RockBand'' during the week of April Fools' Day. In 2008, it was [[VideoGame/{{Portal}} Still Alive]], available for free download. In 2009, three songs from ''WesternAnimation/SpongebobSquarepants'' were released to be sold at a cheaper price than the average song.
** A tradition broken in 2010, when instead they opted to release a JimiHendrix album.
** In 2012, they announced a [[http://www.youtube.com/watch?v=ueS7rbHqo_k&feature=youtu.be board game]].
* {{Furcadia}} has released a number of pranks on April Fools' Day. One prank flipped upside-down and reversed the player's view window of the world on main maps, so navigating was extremely difficult. Another, recurring in some form each year, is a global text filter -- one year, all curse words (and the word 'yiff') were filtered to "NARF". Another year, parodying thesaurus-rape roleplay common on some areas of Furcadia, the word 'eye' or 'eyes' would be filtered to 'orb' or 'oculars'. Another April Fool's pranks have revolved around avatars, in an effort to gain funding for the graphics update; in 2009 there was the Toasterwing event, turning everyone on a main map into a flying toaster; in 2010 there were two localspecies who you would become when one ran into you, the Fluffs and Floofs, and a massive zombie apocalypse battle took place.
* ''GaiaOnline'' has a history of pranking its users on April Fools' Day, often by finding creative ways to blow their heads up.
** In 2004, strange gift boxes appeared randomly around the main site. Users who clicked on them had their faces covered in soot until they changed outfits. "Sootfaces" eventually became a reason not to change your avatar, until the great avatar resave wiped them out.
** In 2005, resident megalomaniac Johnny Gambino built a giant tower. He was assassinated, and the tower fell on top of the mansion of his rivals, The Von Helsons. (They all got better)
** In 2006, resident MadScientist LabtechX made Gino Gambino explode in a SphereOfDestruction that apparently destroyed all of Gaia. No one was killed. (Johnny K. Gambino actually came back to life!) But the explosion did attract a bunch of aliens [[spoiler:because it ripped a hole in the universe. This is a major plot point in the MMO.]]
** In 2007, Gaia did a repeat of its classic 2004 joke, with boxes that apparently gave out Platinum Halos. (The Angelic Halo is one of the most expensive items on Gaia, and a silver version had long been requested). Equipping it gave you a classic "Sootface".
** In 2008, The Easter Bunny (who happens to be a cyborg. [[OldShame Don't ask]]), angry that its holiday was being neglected, gave out Easter Eggs. When April 1st rolled around, users were asked to open their eggs...KABOOM! They also released a special pair of pants that could be worn as a multitude of different things...except, ironically, pants. (That pose was added in on the second)
** In 2009, in response to [[TheyChangedItNowItSucks complaints about Gaia accepting sponsorships and "selling out"]], Gaia created its most elaborate prank yet. The logo was altered to read "OMNIDRINK", with a tiny "presents Gaia Online" in the corner. A video on the main page implied that Gaia had been forcibly bought out by a MegaCorp, that made products you were not supposed to drink. (Including a hilarious "Personal Improvement Spray", that apparently made you more manly). Players who visited the information page would see multiple messages asking them ''NOT TO DRINK OMNIDRINK PRODUCTS'', and would be given a free sample of "Personal Improvement Spray", with a "CHUG IT!" option. [[YourHeadAsplode The results aren't pretty]].
*** The Gag carried over to zOMG!, Gaia's MMO. Player's logging in will find that Omnidrink has redecorated Barton Town, and that a new ExpansionPackWorld (Based off both Greek and Aztec Mythology) has been added in. Players get a chance to board an Airship that will take them to this new world, but find that it simply takes them to a fake loading screen, parodying zOMG's infamous loading issues from earlier builds. Upon returning to Barton Town, players received an equipable error message.
*** ''users'' began playing along with the ''zOMG!'' prank, by discussing the new world at length and explaining to those fooled that the airship had crashed because it was attacked by an Air Shark (made slightly more believable by the presence of a [[BonusBoss Landshark]] in the beach area). The Air Shark was later homage by an evolving item's pose.
*** The forums played along with the joke as well, and began a war between those who had been brainwashed by OMNIDRINK, and the resistance.
** In 2010 Gaians signed on to find a swf image with a ''video'' repeating "Loading..." over and over. On the left of the image was a button to be clicked, this button led to a 404 SUSHI ERROR page. Later, users were able to gain an item called "[[Franchise/FinalFantasy Phoenix Up]]" from the fake 404 page ...which later turned into a sootface, as well as a bonus pose of a Grunny [[spoiler:coming out of the urn holding Johnny Gambino's ashes]]. They also added several blaring banner ads, some that even covered up avatar editing and trades. As of now there's no proof they were connected, but it ended up backfiring, and the developers fixed it.
*** Also, [[MoneySink [=Dernier* Cri=]]] returned with a single item that cost '''300 million gold''' and was only about a few pixels wide. The description says that it was made for "commemorating a very special day", which shows that Brennivin is at least in on the joke.
** In 2011, Gaia decided to do SomethingCompletelyDifferent. Mike Sego stepped up for the job of replacement CEO after Craig decided to step down to pursue his own interests. When word got around that Mike had worked for Facebook in the past, there were considerable fears and doubts within the userbase concerning how he'd handle the site, eventually morphing into rumors that Facebook had in some manner acquired Gaia and was ruining the site. So much like Omnidrink, the staff relieased the Meowbook event as a response to the rumors. The forum posts all showed people with a few randomly chosen cat head clippings imposed over their avatar's head, emotes all recived a visual overhaul to give them cat ears, even the shop keepers were given cat heads. A Premium Cat Feast item could be claimed over the entire weekend by clicking the "brought to you by Meowbook" banner underneath the regular Gaia logo and clicking the submit button on the fake Meowbook signup page.
* ''VideoGame/CommandAndConquer: Red Alert 3'' has a freaking [[http://www.commandandconquer.com/portal/site/redalert/article/detail;jsessionid=EEDACC217CE8713253CD4969EAAA0B8B.ea-e-h-p-del1-3?contentId=5dfe783be5260210VgnVCM100000100d2c0aRCRD Mammoth Tank]] on 2009, which is essentially living mammoths outfitted for war. Though this didn't work terribly well, considering how silly the game already was (War bears, anyone?).
* Every year, some gaming magazine/website or another announced that Nintendo and Camelot were finally making ''VideoGame/GoldenSun 3''... then it was actually announced at E3 2009, which was sadly nowhere near April 1.
* Not even ''VideoGame/{{Touhou}}'' is safe from this. On March 31st, 2008, a [[http://www.youtube.com/watch?v=W9mVq2kZ9co&fmt=18 false trailer for a spinoff RPG]] was released. The fact that the trailer was a hack of ''ValkyrieProfile'''s engine, along with having very professional-looking graphics and remix of an official Touhou track, just made the revelation that it was all a lie and this amazing-looking game would never ever be playable hit even harder.
* ''KingdomOfLoathing'' has done [[http://kol.coldfront.net/thekolwiki/index.php/April_Fool%27s_Day a joke each year]] since 2005.
* In 2008, the ''PuzzlePirates'' staff "accidentally" allowed everybody to read a (fake) staff-only forum, which was filled with posts like "Bug report: My 'send instakill' button is grayed out."
* In 2000, Cyan announced Myst Mayhem, ''VideoGame/{{Myst}}'' turned into a FirstPersonShooter game. The gun-turret tower and foreground gun did appear as {{Easter Egg}}s in real!Myst.
* ''VideoGame/LittleBigPlanet'' (PS3-only) had free "Hessian Sackboy Fragrances" {{DLC}} for a limited time (one week from April 1, 2010). [[http://www.youtube.com/watch?v=GTcl6qjGGTI They're simply extra hand animations.]]
* ''VideoGame/BlazBlue'' [[{{Crossover}} versus]] ''VideoGame/ArcanaHeart''. [[http://www.youtube.com/watch?v=UueBeEaS-fQ This was found on Arcsys's website]].
** Which became (more) HilariousInHindsight when [[MagicalGirl Platinum The Trinity]] was announced for ''VideoGame/BlazBlueContinuumShift'' DLC.
** And when Arcsys announced they would port ''Arcana Heart 3'' to console.
** More when Creator/MikakoTakahashi (Heart Aino's seiyuu) guest stars into VideoGame/BlazBlue's official radio show 'Bururaji' and rechristened it for one episode 'Araraji'. ''Complete with VideoGame/BlazBlue chibi style sprite for Heart'' (they did it with [[VideoGame/GuiltyGear Sol]] already...)
* ''RuneScape'' has done several. In 2004, they announced that a cowboy-like merchant named Diango was selling Horses, which players had wanted to see in the game for a while. He was selling Horses- toy horsies.
** Diango was later re-used in the 2005 and 2008 jokes, where two more popularly demanded items, dragon platebodies and dragon kite shields, usually abbreviated to "Dragon Plate" and "Dragon Kite" respectively, were sold. They were actual plates with a dragon on them, and kites with a dragon on them that could be flown. These joke items remained in the game after April Fools' Day, although re-named to make the fact that they were jokes more obvious. Dragon Platebodies and Dragon Kite Shields were actually added to the game later.
** Their 2007 joke was a fake newsletter on the front page claiming a lot of silly cabbage-related updates were going to be released that month, with an actual newsletter being released the following day.
** In 2009, they did something else cabbage related by making cabbages wieldable, and gave the ability to make some of the cabbages in the game able to move on their own and be kicked- with the secret joke that if you kicked one from Falador to Oo'glog (Which takes a really long time), the Cabbage King, Brassica Prime (mentioned in the 2007 joke) would show up and congratulate you.
** In 2010, they announced that they were making a RuneScape theme park in England. It was an obvious joke, but some people thought it was real anyway until they revealed it was a joke the following day.
** For 2012, they proclaimed that "P-hats" would be dropped all around [=RuneScape=] for players to pick up for free. ("P-hat" traditionally refers to the ultra-rare party hats that are some of the most valuable items in the game.) True to their word, major cities were littered with Pea Hats: green peas that you can wear on your head.
** In 2014 they [[TrollingCreator Trolled]] players by announcing on the website that due to a technical error, a section of the forum that was not intended for players to see had become viewable and asked that players not look at it. If you actually fell for the prank you would probably think that Runescape was going to JumpTheShark with all the bad ideas they talked about adding to the game. They also changed the animation for throwing logs into a fire to look like you were throwing party hats (one of the most expensive items in the game) into the fire.
* Some versions of ''VideoGame/FootballManager'' have an EasterEgg / April Fools gag that shows up only when both the in-game date and the actual date is April 1st.
* Every April 1, {{Creator/Bungie}} releases new information about ''Pimps at Sea'', which apparently has the most advanced and complex economy in a game, ''ever''.
* ''VideoGame/LeagueofLegends'' has dabbled in this a few times.
** In 2009, they announced that Urf the Manatee (who uses [[ImprobableWeaponUser a Spatula and a Chicken foot]] as his weapons) would be added to the game, but it was quickly revealed to be a joke.
** In 2010, they did it again, but made it look much more official. Shorty before Urf was supposed to be released, it was announced that another champion, Warwick, had killed and skinned him. A skin was briefly released for Warwick that showed him wearing Urf, and all the proceeds were donated to real-life Manatee Preservation Groups.
** In 2011, they posted a set of patch notes that would either be ridiculous in a game balance method, uses MemeticMutation, or are otherwise pointless changes to make a joke on an aspect of the characters being 'changed'. In addition to this, they announced that the Blind Monk champion, who was dropped early in the game's development, was going to be released, but all the promotional material they released for him made him look to be the most brokenly overpowered champion in the game. When he was actually released, Lee Sin, the Blind Monk, was actually a well-balanced champion.
** In 2012, a video was released advertising an upcoming 3D viewing option for the game.
** In 2013, there was a ''VideoGame/{{Rampage}}'' parody starring Cho'Gath, which also contained a ''Jetpack Joyride'' parody with Teemo as an EasterEgg (Astro Teemo).
** In 2014, they revealed Ultra Rapid Fire, a set of changes they dubbed "the next evolution of League of Legends" which included things such as removing everyone's mana or energy costs and giving everyone 80% cooldown reduction, x5 passive gold generation and a host of other fun bonuses.
* ''VideoGame/{{Minecraft}}'' had an [[http://www.minecraftwiki.net/wiki/Locked_Chest in-game]] TakeThat at ''VideoGame/TeamFortress2'''s crate system for April Fools 2011.
** In 2013, [[http://www.minecraftwiki.net/wiki/Minecraft_2.0 Minecraft 2.0]] was released, including overfeeding, tinted glass, and an event known as VideoGame/SuperHostile Mode, where a huge number of lightning bolts strike the ground around the player and a huge number of hostile mobs spawn.
* [[http://www.nick.com/games/the-fairly-oddparents-unfairly-oddparents.html Unfairly OddParents]] ''is'' an April Fools joke, composed primarily of [[MeaningfulName unfair]] TrialAndErrorGameplay.
* An example that very rapidly became HilariousInHindsight: in 2006, Gamespot did [[http://www.gamespot.com/news/april-fools-analyst-revolution-will-take-lead-in-2010-6146958 an April Fools' article]] predicting the triumph of the console then known as the Creator/{{Nintendo}} [[UsefulNotes/{{Wii}} Revolution]] in the next UsefulNotes/{{console war|s}} on the strength of its low price (for both the console and its games), its [[VirtualConsole library of classic, inexpensive downloadable titles]], and its ability to tap into markets that aren't thought of as "core gamers". Did we mention that this was meant to be an April Fools' joke?
* The teams of two indie fighting games produced fake screenshots for supposed retro handheld versions of their series in 2012: ''VideoGame/SkullGirls'' had Skullgals for the UsefulNotes/NeoGeoPocket Color, and the familiar puke-green classic Game Boy colors found their way to the supposed DSiWare "Nettou VideoGame/BattleHigh".
* Operation Rainfall, an online campaign famous for getting the Wii games ''VideoGame/{{Xenoblade}}'' and ''TheLastStory'' to the United States, announced that they would add another game to the campaign: ''LovePlus'', a rather notorious DatingSim that is otherwise known as [[DaydreamBeliever "that one game where somebody married one of the characters in real life, ceremony and all."]] Considering the series's reputation, most people smelt a rat, [[SeriousBusiness and some wondered if they were being suicidal]], since they've built up a reputation as crusaders against NoExportForYou. And sure enough, it was a joke.
* peppy, the creator of ''VideoGame/{{osu}}!'' has a knack for adding April Fools' Day jokes to the game, which usually revolve around changes in its genre (touhousu!, a ''VideoGame/{{Touhou}}''/osu! hybrid), gameplay (osu!core, which revolves around random increase in pitch and speed in beatmaps) and beatmaps (pretending to approve and praise an extremely poorly made beatmap).
** Some of these pranks have become official, though: the osu!core mechanic is still available in the game as the hidden Nightcore mod and touhousu! has been confirmed to be in development by peppy.
** The forums would also join in on the April Fools' Day pranks.
* Four Leaf Studios, the group behind ''VisualNovel/KatawaShoujo'', has had one every year since 2008.
** [[http://katawashoujo.blogspot.com/2008/03/4ls-announces-new-project-kss.html 2008]]: The announcement of ''KSS: Katawa Shoujo Shoujo''.
** [[http://katawashoujo.blogspot.com/2009/04/technology-prevails.html 2009]]: Katawa Shoujo will be '''fully voiced'''.
** [[http://katawashoujo.blogspot.com/2010/04/katawa-shoujo-anime-officially.html 2010]]: In conjunction with Creator/StudioDEEN, Katawa Shoujo will have an anime series.
** [[http://katawashoujo.blogspot.com/2011/04/announcement-future-plans.html 2011]]: Future plans to add two more routes, bonus content, exclusive merchandise, premium content (such as the ability to ''save your game''), and no advertising, all because it would now be hosted by [[http://www.katawa-shoujo.com/steam/Steam.htm Steam]].
** [[http://katawashoujo.blogspot.com/2012/04/katawa-shoujo-hd-rerelease.html 2012]]: It didn't stop just because the game had been released. Now available in HD with all objectionable content removed.
** [[http://katawashoujo.blogspot.com/2013/04/katawa-shoujo-2-cancelled.html 2013]]: Plans for ''[=KS2=]'' are cancelled. Instead, they will proceed to ''[=KS3=]''.
* Creator/ParadoxInteractive had two jokes in 2013:
** ''Crusader Kings Z'', a new expansion for ''VideoGame/CrusaderKings 2'', which would unleash zombies upon medieval Europe, and even allow you to play as a zombie. It was also something of a TakeThat to their own BrokenBase with regards to the ''Sunset Invasion'' DLC.
** EuropaUniversalis: TheMusical, complete with a [[http://www.youtube.com/watch?v=3H67FQX5ZLE making of video]] and [[http://www.youtube.com/watch?v=xApYF0xvvd8 three]] [[http://www.youtube.com/watch?v=8yfiZxG_O54 complete]] [[http://www.youtube.com/watch?v=aiEOVsAgw2c songs]]. The plot would have involved [[TinyGuyHugeGirl a romance between France and Ulm]]. The songs later received music videos that doubled as (actual) trailers for ''VideoGame/EuropaUniversalis IV''.
* For 2011's April Fools' Egosoft published a [[RealTrailerFakeMovie fake trailer]] for ''[[http://www.youtube.com/watch?v=QlAWC2HSOYM Nautilus]]'', an animated film set in their ''VideoGame/{{X}}-Universe'' series. In 2012 they claimed that ''VideoGame/XRebirth'' has a ''VideoGame/DanceCentral'' [[http://www.egosoft.com/news/images/news_2012_03_29_001.jpg method of lowering prices]].
* [=ArenaNet=], creators of ''GuildWars'', began running relatively low-key pranks in 2007. Each year a set of joke updates is made public along with an additional one-day change to the game.
** 2007: All players are gender-swapped.
** 2008: All players are converted into stick-figures.
** 2009: All players are converted into Gwen-chan, a chibi-deformed version of story character Gwen.
** 2010: All players are scaled down to the size of miniature pets. All miniature pets are scaled up to normal size.
** 2011: The quest "Annihilator", a ''{{Terminator}}'' spoof, is made available, featuring time travel to stop the Annihilator golem from killing Gwen's mother.
** 2012: The quest "Annihilator II: Searing Day" is made available, featuring time travel to stop the G-1000 from killing Gwen as a child. Character dialogue lampshades many criticisms of the ''Prophecies'' storyline, especially the fan base's mockery of Prince Rurik.
* Creator/WayForwardTechnologies
** On 2013, [=WayForward=] announced its newest original property: ''[[http://www.wayforward.com/blog/2013/4/1/get-ready-for-wayforwards-latest-epic-adventure-cat-girl-wit.html Cat Girl Without Salad]]'', a [[NinjaPirateZombieRobot puzzler, platformer, shmup, action, shooter, adventure, strategy, fighting, rhythm, arcade, horror, tactical, RPG, TPS, RTS, visual novel]] about [[CatGirl Kebako]], a female space BountyHunter and [[SupremeChef four-star chef]] searching for love and adventure. It will be released [[ComicallyMissingThePoint exclusively to Nintendo 3DS, DS, Wii, Wii U, XBLA, PSN, PC, Vita, iOS, and Android]].
** 2014 had them announcing their next big video game project: The [[http://www.wayforward.com/blog/2014/4/1/wayforward-announces-their-next-big-project.html Blocolus VR]], which will create an instant VideogameDemake of whatever you're currently playing. As a bonus, it'll also [[GenderBender gender-swap the male hero]] of any game.
* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' fangame ''VideoGame/LegendsOfEquestria'' announced on its forums on April 1st 2014 that it had been purchased by {{Website/Facebook}} for a million dollars. The forum post even included a fake screenshot of the game running on a Facebook webpage. This was an obvious TakeThat at Facebook's purchase of the OculusRift.
* The Frostbite engine (used in the ''VideoGame/{{Battlefield}}'' series among other things) is incapable of running on WiiU hardware without severe issues (though this has been brought into question when Crytek later confirmed that the latest version of Cry Engine, a more taxing engine, can run just fine on Wii U hardware). Despite this, its developers announced in 2014 that they would back-port the engine to the console anyway and went on tweet what were allegedly progress updates. This development, however, read less like harmless joking and more like an excuse to fire off some of the pettiest, most vicious anti-Nintendo and -Wii U {{Take That}}s imaginable. It was taken to [[DudeNotFunny such an extreme]] that Creator/ElectronicArts COO Peter Moore eventually issued a public apology and deleted the offending tweets after the inevitable InternetBackdraft, with the Frostbite twitter account being updated to say that the offending programmer was acting alone and did not represent EA as a whole.
* Rovio Entertainment leaked [[http://www.rovio.com/en/news/blog/484/draft-eagle-eye-vr-headset-with-angry-birds-simulator/ a rough draft of a fake press release]] for ''VideoGame/AngryBirds Eagle Eye'', a virtual reality headset for playing Angry Birds simulations. In addition, the ''VideoGame/BadPiggies'' [[CharacterBlog Facebook and Twitter feeds]] announced that [[https://www.facebook.com/badpiggies/posts/639111756169114?stream_ref=10 birds are cool]] and [[https://twitter.com/BadPiggies/status/451042423523655681 they now like celery rather than eggs]].
** For 2015, Rovio released a preview for a fake game called ''[[https://www.angrybirds.com/blog/agri-birds--an-all-new-angry-birds-adventure Agri Birds]]'', a game about the birds trying to save their farm from the Mighty Bagel, who intends to demolish it into a golf course. The birds are given limbs, Hal is reimagined as Sasha Lynx, and there is a GameplayRoulette -- in addition to the farming simulation, there's a LightGunGame where Matilda shoots moles, a VirtualPaperDoll featuring the aforementioned Sasha Lynx, a VisualNovel mode in which characters interact with each other, and a SurvivalHorror sequence where the player is stalked by [[TheDividual the Blues]].
* The development team of ''VideoGame/MightyNo9'' released [[http://www.youtube.com/watch?v=WTogbZDTgvE a video of the latest build of the game]]... [[spoiler:only to show fake gameplay footage of Apple No. 1, originally presented as [[http://www.kickstarter.com/projects/mightyno9/mighty-no-9/posts/743176 a fakeout reveal for Mighty No. 7]]. Information is also presented for Apple No. 2 and Apple No. 3.]]
** The following year, [[http://www.youtube.com/watch?v=WmMRYKHmmUE a video for the game's EX mode]] is published, showing... [[spoiler:a music video for "What is Might?" featuring a composite of Ray and Apple No. 1]].
* The developers at [erka:es] has pulled a few for ''VideoGame/{{Rosenkreuzstilette}}'':
** Years before the sequel's development, they posted mock screenshots of ''[=RosenkreuzStilette=] Freudenstachel'' on their website.
** One was planned but was missed due to personal issues, which involved Liebea Palesch's brother Kahl parodying the classic ''Franchise/{{Castlevania}}'' series with Kahl as an expy of Simon Belmont.
** In 2013, a short-lived ''[=RosenkreuzStilette=] Lustatem'' April Fool's site was dedicated to the RKS's resident {{Cloudcuckoolander}}.
* [[NasuVerse TYPE-MOON]]'s April Fools usually consist in changing their website for some outrageous concept starring their proprieties. To wit:
** 2005: ''Neco-ARC: the Movie'', a film starring everybody favorite JokeCharacter from MeltyBlood.
** 2006: ''Hazakura Romantic'', a seemingly original [[YaoiGenre BL novel]] concept (co-opted with NitroPlus) that left many people wishing for their {{Defictionalization}}.
** 2008: Type Moon as a [[ProfessionalWrestling girl wrestling promotion]]!
** 2009: moon.cinemas.jp, a site imitating a typical movie theater chain front page, where all the movies were parodies of well known films (up to including a parody of ''[[Franchise/TrainMan Densha Otoko]]'' starring [[Literature/FateZero Weaver Velvet and Fate/Zero!Rider]] that was revived as the April Fools joke for ufotable in 2012). HilariousInHindsight because one of the "movies" announced, one based in the (then book only) epilogue for the movie series of ''KaraNoKyoukai'', was eventually done and released for real.
** 2010: Rather than fully changing the main page as in former years, {{Twitter}}- saorry, [[CharacterBlog TMitter]] feeds were added to the site. Hilarious and ''very'' in character Twitter feeds from their most popular characters.
** 2011: Instead of a typical joke, for their main page they released a serious short story about the very concept of April Fools, titled "The Room of the April Witch". For their mobile site, on the other side, they reprogrammed it to show a different (parodic) image and accompanying text with each reload.
** 2012: ''Koha-ACE'', a poster for a movie parodying ''Anime/GundamAGE''. The accompanying texts did a self-deprecation number on their [[{{Vaporware}} constant delays on]] ''VisualNovel/MahouTsukaiNoYoru'''s release, through.
** 2013: ''Back Alley Satsuki - Chapter Heroine Sanctuary'' a hilarious parody of ''Anime/SaintSeiya: Sanctuary Chapter'', with new episodes being released during the day. Featuring a lot of characters from their lesser known franchises, and even a character from a light novel written by a member of the staff of the [[DevelopmentHell eternally unreleased then-visual-novel-now-anime]] ''Girls' Work''.
** 2014: The return of the TMitter! Also, TM-channel, a series of NicoNicoDouga-like "streams" of several characters, some of them done in a vlog style.
** 2015: A triple combo: the "release" of a new character for the capsule minigame in the PlaystationVita version of ''VisualNovel/FateHollowAtaraxia'', a Franchise/{{Pokemon}}-style championship on said game (complete with [[BlandNameProduct A-tuborudo and The Big Ben Company]] branding), and "Imperial Roma", a talent agency launching the idol careers of several chharacters ([[Videogame/FateExtra Nero]] being the main spotlight), complete with release dates and everything. Also the [[CharacterBlog TMitter]] is back again.
** There is also ''Fake/states night'', a joke spinoff concept written by [[Anime/{{Baccano}} Ryohgo]] [[Anime/{{Durarara}} Narita]] of all people as a April Fools for his own site. Later released as ''Literature/FateStrangeFake'' in the official TYPE-MOON magazine.
* In 2015, Capcom announced a special version of ''VideoGame/DaiGyakutenSaiban'' where every character is an anthropomorphic dog. And Franchise/SherlockHolmes is replaced with Anime/SherlockHound.
* For a single day (April 1st 2015), ''Videogame/DyingLight's'' physics were changed to preposterous ragdoll levels that lets you send enemies flying away with a single hit.
* In 2015 ''VideoGame/StarTrekOnline'''s devs [[http://www.arcgames.com/en/games/star-trek-online/news/detail/9119293-star-trek-online%3A-rebirth made a big deal]] about a ''Star Trek Online: Rebirth'' that was now live on the Redshirt testing server. A careful reading of the release makes it pretty clear that what's actually going on is they brought back the original release build of ''STO'' for the day.
* The team behind ''VideoGame/ProjectM'' likes to release special videos on this day, always ending with a fake tease of a brand new character:
** [[https://www.youtube.com/watch?v=Z92MxCndZa4 For 2013]], Turbo Mode is revealed, although the video depicts it as a massive overhaul of the core gameplay. The character of the year is [[VideoGame/PokemonGoldAndSilver Pichu]] (specifically, the spiky-eared version from ''[=HeartGold=]'' and ''[=SoulSilver=]'').
** [[https://www.youtube.com/watch?v=tCXABhlj3nI For 2014]], gameplay is shown of two characters: Ike Climbers (a mix between Ike and the Ice Climbers) and [[Franchise/StarFox Slippy Toad]] ([[TheChewToy who isn't shown fighting back]]). The character of the year is [[VideoGame/{{Metroid}} Ridley]].
** [[https://www.youtube.com/watch?v=dOuXKCvhTvw For 2015]], [=PMDev=] claimed that they're hacking the original N64 game instead, with the footage showing players with skins based on the original ''Super Smash Bros.'' for Nintendo 64. Sheik, Charizard, Falco, Ganondorf, Sonic, Diddy Kong, Bowser, the Ice Climbers, Olimar, Mewtwo, Mr. Game & Watch, and Snake all get matching {{Retraux}} skins. The character of the year is [[VideoGame/PokemonRedAndBlue Parasect]].

[[folder: Web Animation]]
* The ''{{asdfmovie}}'' series has a possible example: two days before April Fools' Day 2011, creator [=TomSka=] and animator [=RageNineteen=] responded to fan [=ZxHeiserxZ's=] request "Make an ASDF film/movie for like 20 mins or so :D" by making the StylisticSuck-filled ''[[http://www.youtube.com/watch?v=15rEf75OHNM THE TWENTY MINUTE ASDFMOVIE]]'' [[LiteralGenie in 20 minutes]].
* ''WebAnimation/HomestarRunner'' has done a few April Fools' Jokes.
** In 2003, homestarrunner.com became kingoftown.com, complete with a new intro and main page featuring the [[UnpopularPopularCharacter not-at-all-popular]] incompetent ruler of Free Country, USA. ("King of Town! Hooray!")
** In 2004, the site was replaced with a bogus domain registration site from the fictional Thorax Corporation... which was actually a flash cartoon where Stinkoman showed up to fight a animated GIF of a shovel-wielding stick figure. ("Hey, Stickly Man, whaaaat are you doing?")
** In 2005, the site was replaced with a (fake) main page for a subscription service, [=HomestarRunner.com=] Pay PLUS!
** In 2006, all the cartoons and main pages on the site were flipped upside-down. This caused some problems with ActionScript on the site, and, to two tropers' dismay, the Strong Bad Email "Virus".
** In 2009, the Monday before had featured a cartoon called "Sbemailiarized Entertainment", in which after a long lack of [[FourthWallMailSlot Strong Bad E-mails]], Strong Bad decided there wasn't really a big difference between sbemails and other cartoons, and he could just stick himself answering an e-mail at the beginning and end of any old cartoon and it would work. After a very long prank hiatus, the day itself had the intro movie replaced by a Sbemailiarized version.
** In 2010, the site's intro was suddenly replaced with [[XtremeKoolLetterz HSR Xeriouxly Forxe]], a parody of DarkerAndEdgier.
** In 2014, the site got its first update in 4 years! The new toon is full of Homestar and Strong Bad {{lampshad|eHanging}}ing how the site hasn't been updated in such a long time, and the two update aspects of the site that are mere footnotes from the site's early days (including what seems like a tease for a new Strong Bad Email... that ends with minor updates to the all-but-forgotten Windows 98 desktop themes).
** In 2015, the site announced the first Strong Bad Email in about 5 years. The actual video has Strong Bad trying to read emails off various electronic appliances before remembering he has a computer. When he realizes it's April Fool's Day, Strong Bad refuses to answer any emails and starts to rant about how the internet ruined the holiday. He then decides to celebrate April Fool's Day the traditional way; [[AprilFoolsPlot by pranking people in person]]. He finally waits until midnight (in-universe) so that it's not April 1 any more, and decides to check an e-mail for real. [[spoiler:At which point the cartoon abruptly ends with "April Fools!"]]
* Episode 17 of ''MakingFiends'' was released on April Fools' Day. Absolutely nothing was strange about it. Well, besides the fact that every dialogue was spoken in Bulgarian. A subbed version was later released... in IntentionalEngrishForFunny.
* In 2008, [[WebAnimation/SuperMarioBrosZ Alvin Earthworm]] made an animation of the head from ''Mario Teaches Typing 2'' giving a RickRoll. [[http://www.youtube.com/watch?v=mR0C55F8Eqg See it here.]]
** In 2009, he redid a fight scene from the most recent episode, but with all the characters' sprites replaced by images of [[VisualPun Sprite cans]]. In addition, the background was replaced with sausage packs.
** In 2010, [[http://www.youtube.com/watch?v=XQljOzqSGMI Luigi is Dio Brando.]]
* [[https://fbcdn-sphotos-c-a.akamaihd.net/hphotos-ak-xfa1/v/t1.0-9/s526x296/1926915_727977833903660_1703382582_n.png?oh=da3931f9f95a33414ef726b5e427a290&oe=54D8AA69&__gda__=1424890425_782d426cf9f315020c9267d41d431475 This image]] was released on the ''WebAnimation/InanimateInsanity'' Facebook page on April 1st, 2014. Obvious backlash ensued.
** On April 1st 2015, a video was released which started with the cast appearing to be [[KillEmAll killed]] due to the overflow of views on ''Inanimate Insanity II''... only for the typical April Fools Day horn to play and for an update to the store to be announced.[[note]]This was the climax of a completely different prank Adam tried to pull, but it backfired spectacularly.[[/note]]
* WebAnimation/ZeroPunctuation's April Fools gags:
** In 2009, the hosts of {{Unskippable}} pretended to stage a HostileShowTakeover and reviewed VideoGame/XBlades before Yahtzee seized the show back to review Franchise/{{Halo}} Wars. Yahtzee also guest-commentated on {{Unskippable}}.
** In 2010, the usually MotorMouth Yahtzee recited ''Ode to Melancholy'' in a very slow, ponderous manner.

* In late March 2006, the Chris Hastings and Kent Archer of ''Webcomic/TheAdventuresOfDrMcNinja'' posted on the site news that they thought they were being stalked by ninjas. On April 1, this was followed up by a post in which the ninjas killed Hastings and Archer, then imitated them and announced the end of the comic.
** In 2008, they put up [[http://drmcninja.com/page.php?pageNum=9&issue=11 this comic,]] which was only ''slightly'' odder than the comic's usual fare.
*** In 2009 they began a new campaign of in-strip product placement, while on the newly fan-run forums a campaign of [=McNinja=]-themed word filtering of random phrases was enacted.
*** In 2013, ComicBook/SpiderMan [[http://drmcninja.com/archives/comic/25p96/ bursts in to save the day]], and brings along [[Literature/LordOfTheRings Gandalf]], Franchise/{{Robocop}}, [[Franchise/StarWars Boba Fett]], and [[Franchise/SuperMarioBros Mario]].
*** In 2014, Chris Hastings posted that he was experimenting with a new style that would help him make more comics, faster. [[http://drmcninja.com/archives/comic/27p32/ The new style]] was the ''Webcomic/DinosaurComics'' template.
* ''Webcomic/TheBookOfBiff'' did this at least twice. In both instances, an established element of the comic is rendered differently and the author blocks out any comments pointing these out. The very next day he unblocks the comments, posts the non-joke version of the same comic, and moves the joke comic to a different page.
** In 2008, Biff's [[UnusualEyebrows face]] looks [[http://www.thebookofbiff.com/fools.html normal]].
** In 2009, [[TheSpeechless Biff]] [[http://www.thebookofbiff.com/2009-April-Fools.html speaks]]!
* In 2009, ''Webcomic/BrawlInTheFamily'' was briefly replaced with the rather bizarre ''[[http://www.brawlinthefamily.com/comic151.html Waluigi in the Family]]'', or [=WitF=], starring Waluigi. It updated 17 times over the course of the day. The eight-digit strip numbers were a nice touch.
** In 2010, the front page was adorned with a [[http://www.brawlinthefamily.com/?p=1118 "letter from Nintendo"]] ordering the comic to shut down. It listed the comics that Nintendo had issue with, and their offenses. [[spoiler:In summary, the letter ordered the comic to shut down because Waluigi hates it.]] Underneath the letter, there were also new ''Waluigi in the Family'' comics.
** In 2011, the comic was called "Philips' Box", with its jokes based on the CD-i games. The main story was that Mario hits a box, freeing the spirits of the CD-i games. Over time, King Dedede goes crazy since Kirby, Waddle Dee and Adeline had been possessed by the spirits and wonders what could end their insanity. At that moment, Waluigi comes back from his vacation and scares the spirits away back into the box.
** In 2012, the author was sick, so he wrote a Waluigi apology letter.
** In 2013, he announced he was turning the webcomic into a VideoGame/PlaystationAllStarsBattleRoyale fancomic.
** In 2014, the author brought back Waluigi in the Family, concluding with a comic in which Daisy and Luigi tell Waluigi off, and he goes to work for Wario at Wario Ware Inc.
** The comic was still at it even in 2015, after the comic had officially ended! An image was posted on the front page of the website, claiming ''Brawl in the Family'' had been {{uncancelled}}. Then you scroll down... "[[ILied Just kidding.]] [[SelfDemonstrating/{{Waluigi}} Waaaa.]]"
* In 2008, ''Webcomic/DarthsAndDroids'' (which uses images from the ''Franchise/StarWars'' films) claimed they had received a cease-and-desist letter from Lucasfilm, and would henceforth be making the comic using [[http://www.darthsanddroids.net/episodes/0082.html photographs of themselves]] re-enacting the films. (Move mouse over the comic image)
** In 2010 the narrative switched from being a gaming session into a ''Film/ThePrincessBride'' [[http://www.darthsanddroids.net/episodes/0395.html tribute]].
* ''Webcomic/QueenOfWands'' very briefly put up a shot of one of the characters tearfully confessing she was pregnant, to fan concern. Soon after, this was replaced by a different, jokey comic. Later in the StoryArc, the same pregnancy scene was used exactly and unironically. On April 1st.
* In 2008, ''Webcomic/DinosaurComics'', ''Webcomic/QuestionableContent'', and ''Webcomic/{{xkcd}}'' all temporarily stole each other's websites.
* In 2009, the author of ''Webcomic/{{Goblins}}'' claimed that the author of ''Webcomic/LeastICouldDo'' had [[http://leasticoulddo.com/comic/20090326 used one of his characters]] without permission and that he was suing.
* In 2008, ''Webcomic/GunnerkriggCourt'' replaced the [[http://www.gunnerkrigg.com/archive_page.php?comicID=385 latest page]] (at the time) with [[http://static.tvtropes.org/pmwiki/pub/images/gc-aprilfools-385.jpg this.]]
* ''[[NOfNA Nature of Nature's Art]]'' added a temporary panel one AprilFoolsDay where, after [[spoiler:Meander]] kills [[spoiler:Rule]], the corpse gets back up and says, BOO.
** 2010's April Fool's joke is an elaborate and surprisingly thoughtful comic about a sullen looking man who adopts a Pikachu, [[spoiler: Shows it enough of the world and all of its good and evil that it becomes enlightened]], and uses it to win a tournament. It really has to be seen to be believed.
** 2011 continued the tradition with a comic about a man who creates "the next human brain". [[spoiler:And then the Pikachu from last year's April Fools comic shows up and takes him into another dimension. Or something like that.]] It's a bit of a MindScrew.
* For 2008, in ''Webcomic/ThePhoenixRequiem'', Jonas gets into his TARDIS and vanishes (pictured above).
* In 2009, ''Webcomic/{{Shortpacked}}!'' ran [[http://shortpacked.com/comic/book-8/08-heroic-bsod/roomies/ this]] ''Webcomic/{{Roomies}}'' [[http://shortpacked.com/comic/book-8/08-heroic-bsod/roomies/ comic]], with the explanation that, since the ''Shortpacked!'' storyline had become [[http://shortpacked.com/comic/book-8/08-heroic-bsod/gpf/ fundamentally broken]], Willis was doing a reboot of the entire {{Walkyverse}}.
** Which is now HilariousInHindsight with the coming of DumbingOfAge...
** In prior years, Willis ran ''Webcomic/DinosaurComics''[[http://shortpacked.com/comic/book-1-brings-back-the-80s/03-customer-protection-rackets/aprilfools/ -esque strips]], recycling the artwork in subsequent years in ''Dinosaur Comics'' fashion.
** One prank in particular April Fools changed Shortpacked's site layout to that of "EvilTwin" [=McAwesome's=] which in fact, introduced them.
* In 2008, ''Webcomic/TheWotch'' celebrated by having Robin abruptly decide, "Oh, who cares if this makes sense or not, I'm doin' it!" and [[http://www.thewotch.com/images/4108Joke.jpg dramatically smooch Cassie]]. 2009 took a different angle by saying that since Anne (the author) had hurt her arm, which she had, Jason would be [[http://thewotch.com/?epDate=2009-03-31 taking over the artwork]] for the next month. It actually went over pretty well, even among those who bought it.
* ''Webcomic/ElGoonishShive'' had not one but two non-canon arcs for April Fools' Day, the first (called April Fool's Week) consisted of odd fillers that featured things like Tedd and Sarah making out, Sarah becoming a Were-Squirrel and the page not actually being drawn one day. The second (known as II slooF lirpA) followed Dan accidentally altering the rules of the dimension, transforming all the characters.
* ''Webcomic/TheWhiteboard'' has done an AFD strip since the first one after the strip began, most of them playing on the general theme of FanService. In 2009, the author changed the front page to look like a directory listing, including folders for "alternate storylines", a "passwords" text document, and a well-executed Rickroll. Readers actually called the site's host to warn them of the security hole.
* In 2010, ''Webcomic/{{xkcd}}'' redid its main page to look like a Unix terminal, complete with a command line interface and {{MUD}} ShoutOut jokes (type "look", or "go south"). You can still find the terminal [[http://uni.xkcd.com/ here]].
** For 2011, all of XKCD's comics are in 3D. This is also [[http://xk3d.xkcd.com/ still findable.]]
** 2012 brought us [[http://xkcd.com/1037/ a comic]] which becomes completely different comics on different web browsers or operating systems, and sometimes even changes due to your physical location on Earth. One appeared only to people who [[http://forums.xkcd.com/viewtopic.php?f=7&t=82442&start=360#p2951223 signed up to see Randall's talk at CNU.]]
* In 2010, ''Webcomic/QuestionableContent'' updated with a [[http://questionablecontent.net/view.php?comic=1634 page]] straight out of ''[[ShowWithinAShow Magical]] [[BoysLove Love]] [[YaoiFangirl Gentleman]]'', complete with matching page layout. [[CrowningMomentOfFunny Glowing crotches are involved.]]
* In 2010, ''Webcomic/DinosaurComics'' replaced the entire cast with {{Nedroid}} characters (Reginald in place of T. Rex, Beartato in place of Utahraptor, etc). Not just in the latest page, but in the entire archives.
* In 2010, ''Webcomic/UnwindersTallComics'' changed its name and format to ''[[http://tallcomics.com/?id=65 Unwinder's Short Comics]]''.
* In 2010 the ''Webcomic/DresdenCodak'' website was given a LeFilmArtistique paintjob by [[http://www.vimeo.com/10593465 This video]].
** [[http://vimeo.com/39131013 And again]] in 2012.
* In 2009, Several characters from ''Webcomic/NamirDeiter'' and ''Webcomic/YouSayItFirst'' (both drawn and written by the same people) ware swapped for each other, with the dialog for both comics remaining unaltered. In 2010, both comics were drawn with the characters appearing as human.
* ''Webcomic/TheKAMics'' in 2005 [[http://www.theduckwebcomics.com/The_KAMics/4771282/ KAM quit]] which actually started off a short storyline; in 2009, to wrap up a [[http://www.theduckwebcomics.com/The_KAMics/5111920/ humorous]] [[http://www.theduckwebcomics.com/Magical_Misfits/5113530/ disagreement]] between him & the author of ''MagicalMisfits'', [[http://www.theduckwebcomics.com/The_KAMics/5121122/ did this]]; and in 2010 turned it into an April Fools Month turning his various characters into ponies.
* While ''Webcomic/HolidayWars'' has never down a special for April Fools' Day, it does include it as a character. It's portrayed as a [[VoluntaryShapeshifting shapeshifting]] [[TheTrickster prankster]] enslaved to the Easter Bunny.
* ''Webcomic/BittersweetCandyBowl'', [[http://www.bittersweetcandybowl.com/c49/p1.html "In The End"]]
* In 2011, ''Webcomic/HereWolf'' was replaced by the fake comic ''Stupid Priest''.
* ''Webcomic/{{Femmegasm}}'' and ''Webcomic/WorldOfFizz'' swapped artists for April Fools Day in 2011.
* In ''Webcomic/ImpureBlood'', [[http://www.impurebloodwebcomic.com/Pages/SpecialPages/2010AprilFools.html the author and the artist traded roles for the strip.]]
* In 2011, ''Webcomic/BeyondTheCanopy'' [[http://beyondthecanopy.com/?webcomic_post=beyond-the-manopy-188-2 briefly turned into a parody]] of ''FistOfTheNorthStar''.
* In 2002, ''WebComic/EightBitTheater'' had Garland [[http://www.nuklearpower.com/2002/04/01/episode-133-if-you-did-see-it-coming-you-might-be-psychic-joke-comic/ destroy the universe]].
* ''Webcomic/FarOutThere'' pulled the fake "ending" gag in [[http://faroutthere.smackjeeves.com/comics/1067764/page-wait-what/ 2009]] and again in [[http://faroutthere.smackjeeves.com/comics/1071310/page-oh-not-again/ 2010]].
** 2011's [[http://faroutthere.smackjeeves.com/comics/1156080/page-pop-tarts-spiraling-towards-the-earth/ April Fools]] began a tradition of "debuting" a drastically new style: first DadaComics, followed by {{Sprite Comic}}s in [[http://faroutthere.smackjeeves.com/comics/1461524/page-nes/ 2012]], MagicalGirl in [[http://faroutthere.smackjeeves.com/comics/1709321/page-magical-girls-everywhere/ 2013]], and Sentai in [[http://faroutthere.smackjeeves.com/comics/1926565/page-fool/ 2014]].
* In 2012, ''Webcomic/{{Homestuck}}'' did two fake updates that set off the update notifiers without actually adding or changing anything. The actual updates that fell on April 1 involved [[spoiler:the EldritchAbomination BiggerBad ''killing'' the AuthorAvatar]], so they seemed like jokes--but turned out to be a real plot development.
* ''Webcomic/EvilPlanTheWebcomic'' pulls something every year.
** In 2010, they posted what looked like a repeat update of the last page. It was actually a gif, and after a few seconds, it degenerated into an edited ZALGO mess, complete with blood pouring from the characters' eyes.
** In 2011, they had an obviously fake link to download a fictional theme song for the comic. Turned out that the link really DID go to a theme song, by Andrew of SongsToWearPantsTo.
** In 2012, they redesigned the site and did "Planstuck," parodying ''Webcomic/{{Homestuck}}'''s art style and use of gifs. The artist updated throughout the day based on comments from the readers, finally clocking in at 95 updates.
* In 2012, ''Webcomic/TheNonAdventuresOfWonderella'' replaced their homepage with [[http://nonadventures.com/no-nad.html No-Nad Ventures]], a company selling fake testicles for neutered pets.
* In 2012, ''Webcomic/CucumberQuest'' was abruptly retooled as the [[TestosteronePoisoning testosterone-fueled]] ''Cuke or Die II: Cuke Harder''. ([[http://cucumber.gigidigi.com/other-stuff/ Preserved here.]])
** In 2013, all the characters were redrawn to resemble Bacon (i.e. pudgy and piglike), both on [[http://cucumber.gigidigi.com/wp-content/uploads/2013/04/b327.jpg the latest page]] and [[http://cucumber.gigidigi.com/bacon/ the character profiles]]. And all the text on those character profiles was written from Bacon's perspective.
** In 2014, the comic was revamped as ''Kukobu Quest'', resembling a teen's awkward first attempt at a manga-style comic. At the end of the day, [[http://cucumber.gigidigi.com/about-kukobu-quest/ Gigi posted]] to explain that ''Kukobu'' actually was her very first draft of the story that eventually became ''Cucumber Quest''.
* ''Webcomic/{{Educomix}}''
** In the [[http://educomix.thecomicseries.com/comics/43/ 2011 April Fools' Day strip]], [[GenderBlenderName Ma'am]] played a trick on Eyeclops.
** The [[http://educomix.thecomicseries.com/comics/146/ 2012 April Fools' Day strip]] was an edit of the [[http://educomix.thecomicseries.com/comics/1/ first ever strip]] that changed the ending.
* Although ''WebComic/IrregularWebcomic'' doesn't usually do April Fool jokes, in 2007 the author made a [[http://www.irregularwebcomic.net/1526.html comic]] where he appeared formally dressed and announced the comic's discontinuation due to a lawsuit involving every company with copyrights on various elements he used for his comic, with the inexplicable addition of Disney.
* ''Webcomic/CommanderKitty'' has had a couple during its run, starting with [[http://www.commanderkitty.com/2010/04/02/7/ a stick figure comic]], and then followed the next year [[http://www.commanderkitty.com/2011/04/01/my-little-spacers/ with the cast as turning into]] [[WesternAnimation/MyLittlePonyFriendshipIsMagic ponies]].
* ''Webcomic/ButImACatPerson'' for the first time in 2013, [[http://erinptah.com/catperson/comic/chapter-eleven-page-04-01/ fulfilling about a dozen 'ships at once]].
* ''Webcomic/PoppyOPossum'' in 2014 announced a number of drastic changes to the comic on [[http://www.poppy-opossum.com/comic/an-announcement/ April 1st]]. However, the next day's comics revealed that [[http://www.poppy-opossum.com/comic/poppy-3-page-9/ the real joke]] was that there was a bit of canon in it, [[spoiler: Kit actually is blind.]]

* Website/FourChan once added a [[UsefulNotes/FurryFandom /fur/]] channel on April 1st. The userbase was shocked to see it still up on April 2nd. Then they were infuriated when it was ''still'' up on April 3rd. [[spoiler:On April 4th moot closed the channel and [[ThereIsNoKillLikeOverkill permabanned everyone who had posted in it.]]]] The April Fur's Day prank is today [[AcceptableTargets considered one of the better things the staff have done.]] This prank is such a legendary cornerstone of the 4chan community that, when moot added a [[WesternAnimation/MyLittlePonyFriendshipIsMagic /mlp/]] board to stem the sheer number of pony threads on /co/, it was immediately assumed by the majority of the users that the staff were up to their old tricks with an early April Fools prank. It got so accepted as fact that [[WordOfGod moot had to top the board with a sticky thread specifically debunking the rumor]], not that that stopped anyone from still claiming it to be true up until April Fools Day itself.
* [[http://www.backloggery.com The Backloggery]] saw how far you can take {{Cash Cow Franchise}}s to on 2009 by randomly adding suffixes and prefixes of popular video game series, shovelware franchises, SuperTitle64Advance and other generic stuff on games' names as you refresh the pages, leading to some utterly ridiculous ideas like ''Imagine: VideoGame/ResidentEvil5''? ''VideoGame/{{Superman 64}} HD Remix'', the redundant ''VideoGame/StreetFighterAlpha Anthology [[CapcomVsWhatever vs. Capcom]]'', ''Creator/TomClancy's Franchise/SonicTheHedgehog'', and ''GuitarHero: VisualNovel/SayaNoUta Edition''.
* Website/DeviantArt:
** In 2008, the site replaced the avatars of all users with an animated gif of ''[[Franchise/{{Pokemon}} Mudkip]]'' with the words "So I herd you liek Mudkips" (sic), a reference to an [[Memes/{{Pokemon}} internet meme]]. This led to many people being infuriated at the site's staff members for using such a meme when (at the time) they couldn't do memes as well. To make matters worse, it backfired in [=DeviantArt=]'s faces because they also featured an artist user whose account name was along the lines of Mudkipz to go along with the gag.\\
Unfortunately they didn't check out said deviant before featuring him, leading to many to click on his gallery and come face first in very suggestive loli pics (some of which were porn). They removed the featured deviant and chewed out the offensive imagery, but the damage was done and left many red-faced or shaking their heads in addition to the meme.
** On April 1st 2010, avatars were changed to [[Literature/{{Twilight}} Team Edward, Team Jacob]], [[Series/LegendOfTheSeeker Team]] ''[[Series/LegendOfTheSeeker Seeker]]'', or Music/LadyGaga, with matching signatures (though the Team Seeker signatures reflect only ''Series/LegendOfTheSeeker'', and not ''Literature/SwordOfTruth'') Llama badges were also released, which became a huge fad.
** For April 1st 2011 troll faces appeared on random places throughout the website (ironic, since the site has a very strict "No Trolling" policy).
** In 2012, cats took over DA.
** In 2013, dA introduced [=deviantHEART=], a dating service for Deviants.
** In 2014, dA introduced [=thoughtArt=], the new way to create and share art. It supposedly scans your cerebral and turns your thoughts into art. [[ILied Except not.]]
** In 2015, the site introduced the [=DeviantArt=] Stylus IRL, a way to bring the sophistication of digital art into the real world.
* The ''VideoGame/{{Doom}}'' fansite Doomworld.com pulled a couple of pranks:
** [[http://www.doomworld.com/php/topstory.php?id=1878 2003]]: "Doomworld Nearing Its End", as a result of every single staff member leaving for one reason or other.
** 2004: The site was supposedly now "sponsored by [=McDonald=]'s", with the front page decorated with the Golden Arches logo and Ronald [=McDonald=]'s likeness. Also, [[http://www.doomworld.com/php/topstory.php?id=2236 a news item]] was published, stating that ''Doom 3'' has finally gone gold, though with a number of last-minute changes (e.g. all monsters looking lke John Romero, and all levels being completely pitch black.)
** [[http://www.doomworld.com/php/topstory.php?id=2781 2006]]: Claiming that ''Action Doom 2'', a sequel to the popular ''Doom'' mod, was in production. Except it turned out it ''wasn't'' a joke, as ''[[VideoGame/ActionDoom2UrbanBrawl Action Doom 2]]'' was suprisingly released out of the blue two years later.
** [[http://www.doomworld.com/php/topstory.php?id=2893 2007]]: Claiming that the site was shutting down because the doomworld.com domain had been sold to the Christian organization Endtime Ministries.
* Blog/EquestriaDaily:
** 2011: Trixie taking over the site. This more than anything was what really instilled in the fandom that Sethisto really likes Trixie.
** 2012: Converting the website from Generation 4 (Friendship Is Magic) to Generations 1-3.5 (the original My Little Pony to the TastesLikeDiabetes, oddly-bulbous-bodied characters from the series immediately before [=FiM=]). Their reasoning was that they were under a Hasbro takeover.
** 2013: they decided to [[Memes/MyLittlePonyFriendshipIsMagic "monitor everything"]], presenting "ponified" news stories as well as a few fake "updates" about season 4.
** 2014: they set themselves to 2045, and looked back at all [[LongRunners 31 seasons]] of Friendship Is Magic.
** 2015: the site took a more [[TestosteronePoisoning manly approach]] to some of its articles and renamed itself "Man Daily". By featuring Bulk Biceps on the banner, of course.
* ''Website/FimfictionDotNet'':
** 2014:
** Some of the stories on the site appeared as if they were written by someone else. And this applied to any and all stories by that author, even stories that had been posted years before that date and that were clearly ''not'' by that author.
** The administrator, knighty, changed his name and avatar to that of Mark Zuckerburg and claimed {{Website/Facebook}} owned the site, making fun of Facebook buying the Oculus Rift.
** 2015:
*** The announcement post detailing the changes staff did to the featured box was posted on March 31st, 2015 to try to avoid this. However, the day after April Fools, a blog post has been added that clearly states on bold that the feature box has not been changed and that that was a increasingly large prank.
*** The popular Seattle's Angels review group posted several fake stories that link to various things outside of Fimfiction (the coverart for one of these was just the coverart of ''FanFic/PastSins'' with the colours inverted) with even crazier reviews.
*** The administrator posted a blog post (this one more subtle, with several letters in italic that spell April Fools) banning [=LoHAV=] stories on the site[[note]]For those that are unaware, this stands for "League of Humans Acting Villainous" and is increasingly popular on the site. The basic premise is this: a person goes to a convention (almost always Comic-Con) cosplaying as their favourite fictional villain. They find a tricket by a merchant that is just what they need to finish their costume. They then find themselves in Equestria with all the powers of the villain they were cosplaying. HilarityEnsues.[[/note]]
* Furry art site Fur Affinity has its share of pranks. For a few years, the search engine was taken down and one year, it was put back up for that day, but people got fooled when they saw that it didn't work at all. One common joke its members play on its watchers is to use a thumbnail (preview) of a piece of art they claimed to have made and when people click it, the art is something different (example: a thumbnail promises fat fur art and instead, users get an anorexic fur). Usually most members that are aware of the jokes and what the artists usually make usually won't fall for it. Another common joke is an artist making a journal claiming they are going to leave the site forever.
* GameFAQs always gets in on the April Fools Day craze. In later years it's been toned down, sometimes with the only gag being a silly Poll of the Day and maybe the creation of a few joke message boards. But in the past, they've done some huge things, including:
** Banning the latter "e"
** Changing the entire layout to create [=GameFAX=], a site all about the XBox.
** Promoting random users to moderator status (though obviously not giving them actual power)
** Putting up a fake notice on the homepage about the site being shut down for illegal activities
** Removing all usernames in an effort to stop harassment
* Website/{{Google}} almost always has [[http://en.wikipedia.org/wiki/Google%27s_hoaxes a yearly joke]] to pull, ranging from lunar research bases to intelligence-boosting energy drinks.
** In 2010, Google put up a link to a new "Google Animal Translate" feature, and changed its name to Topeka.com in response to the city changing its name to Google, Kansas. [[http://googleblog.blogspot.com/2010/04/different-kind-of-company-name.html Details here.]]
** In 2012, they created [[http://www.youtube.com/watch?feature=player_embedded&v=rznYifPHxDg Google Maps 8-bit]] for the {{NES}}. The video itself [[ShownTheirWork shows its work]] by showing that it is for the Famicom, which had networking features the UsefulNotes/NintendoEntertainmentSystem didn't.
** In 2013, Google announced the release of [[http://www.google.com/landing/nose/ Google Nose]] and [[http://mail.google.com/mail/help/intl/en/promos/blue/index.html Gmail Blue]].
** In 2014, Google introduced the Google Maps {{Franchise/Pokemon}} Challenge free for anyone who owns an iPhone or an Android with the Google Maps application. Simply tap the search bar then press the Press Start button, handily labeled with a Pokéball. The map shifts to the closest Pokémon Center, showing any and all available Pokémon nearby. Catch them all, and you'll win a chance to get a job at Google.
** For 2015, Google introduced a new mode for Google Maps that turns any location that has enough roads into a game of ''VideoGame/PacMan''. This has been up for a few days before April Fools, though.
* I-Mockery releases joke games on April Fool's. In 2008, it was a Pickleman (the site's mascot/creator's alter-ego) game, which was really just E.T. with Pickleman coming after you and killing you. For 2009, it's VideoGame/{{Tetris}} for Charity, where if you get to the 3rd level, $1 is donated to charity. Halfway through the second level, all the blocks are replaced by random NES sprites, which makes the game impossible. For 2010, it's ''VideoGame/{{Pitfall}} 2010'', which looks like the original at first glance, [[spoiler: but depending on the path you take on the first screen, you'll be killed by either the Guts Dozer from ''VideoGame/MegaMan2'', the robot ape from ''VideoGame/{{Strider}}'', or ''{{Sinistar}}''.]]
* ''Website/KnowYourMeme'':
** On April 1st, 2013, the site claimed that the main tubular system was down and that the database could only process memes that predated the Internet. All confirmed memes were still available under a separate "Deadpool" section.
** On April 1st 2015, They replaced the cursor with the Illuminati symbol and replaced all usernames and profile pictures with variations on Don, the sites admin. Also various Deadpooled memes were reopened.
* [[http://www.jayisgames.com/ JayIsGames.com]] created their own [[http://jayisgames.com/games/spot-the-difference/ Spot the Difference]] game that leads into an impossible level. The walkthrough included claims that this was a turning point that leads the game into becoming a DeconstructionGame, but in truth, nothing happens at all if you wait, not even a ScreamerPrank.
** In 2011, they [[http://jayisgames.com/archives/2011/04/tic_tac_toe.php reviewed]] a tic-tac-toe game far too seriously.
** In 2007 they reviewed a supposedly massive browser game that was actually just [[http://bendtome.fizzlebot.com/ a loading screen that never ended]]. After April Fool's they turned it into an [[http://jayisgames.com/archives/2007/04/entombed.php actual review]] of the ''downloadable'' game it was based on.
** In 2009, they had an [[http://jayisgames.com/archives/2009/04/quest_for_the_crown.php overblown review]] of a game called "[[http://jayisgames.com/games/quest-for-the-crown/ Quest for the Crown]]".
** In 2012, they created a genuine, playable TextAdventure game, the joke being its completely ridiculous premise. [[http://jayisgames.com/archives/2012/04/jayisponies.php Jay Is Ponies]]!
** In 2014, they found a site that makes versions of the online game ''2048'' and made a version with the faces of the staff replacing the numbers: [[http://games.usvsth3m.com/2048/jayis2048-edition/ Jayis2048]].
* [=MuggleNet=] posts absurd news items on April 1st, such as claiming Scholastic would rerelease the books with titles like "[[Literature/HarryPotterAndThePhilosophersStone Harry Potter and A Super Cool Stone]]", "[[Literature/HarryPotterAndTheChamberOfSecrets Harry Potter and A Super SUPER Secret]]", "[[Literature/HarryPotterAndThePrisonerOfAzkaban Harry Potter and A Bad Guy Who's Actually Okay]]", "[[Literature/HarryPotterAndTheGobletOfFire Harry Potter and FIREEEEEEEEE!]]", "[[Literature/HarryPotterAndTheOrderOfThePhoenix Harry Potter and A Super Secret House shhh]]", "[[Literature/HarryPotterAndTheHalfBloodPrince Harry Potter and A Prince, Like The One You Know]]", and "[[Literature/HarryPotterAndTheDeathlyHallows Harry Potter and A Good Versus Evil Fight]]". One year they joined forces with ''The Leaky Cauldron'' by claiming that the two webmasters Emerson and Melissa (who were already being shipped as "Memerson") had gotten married and were combining sites.
* In 2010, [[http://agtp.romhack.net/ Aeon Genesis]] finally released their translation of ''TacticsOgre'' [[spoiler: in [[VideoGame/FinalFantasyX Al Bhed]]]].
* Romhack website Romhacking.net put up a link on April 1, 2014 for a translation of Etrian Odyssey Retold, a supposed "hard version" of ''VideoGame/EtrianOdyssey''. [[spoiler:It was actually a full translation for the game 7th Dragon.]]
* Muppet fan website The Muppet Mindset has had many April Fools jokes on an infrequent basis. Besides the website swap with [=ToughPigs=] mentioned below, they've also done [[https://muppetmindset.wordpress.com/2010/04/01/april-fools-copyright-violation/ a fake cease and desist]], an article involving a fake ride at Ride/DisneyThemeParks based around [[https://muppetmindset.wordpress.com/2012/04/01/disney-announces-angus-mcgonagle-thrill-ride/ Angus McGonagle]] (a one-off character from the Franchise/StarWars episode of ''Series/TheMuppetShow'') and temporarily rebranding itself [[https://muppetmindset.wordpress.com/2014/04/01/how-to-get-into-constantine-mindset/ the Constantine Mindset]]. For 2015, they announced dozens of SpinOff websites, from the logical (the Marvel Mindset and the Mario Mindset) to the ridiculous (er... the ''[[MundaneMadeAwesome Macaroni]]'' Mindset?). It reached its epix when they announced "The Mindset Mindset", a blog for fans of all of the Mindset sites. Each post linked to the same picture of Fozzie (a screencap from the Bohemian Rhapsody viral video) with the caption "April Fools!"
** Their ''actual'' SpinOff website, the [[https://mickeymindset.wordpress.com/ Mickey Mindset]], had two articles for April Fools 2015: a potential [[https://mickeymindset.wordpress.com/2015/04/01/is-disney-working-on-a-live-action-a-goofy-movie/ live-action remake]] of ''WesternAnimation/AGoofyMovie'' (a TakeThat at Disney's influx of live-action remakes of their classic works, such as ''Disney/{{Cinderella}}'' and ''Film/AliceInWonderland'') and Marvel's announcement of a Squirrel Girl/Howard The Duck [[https://mickeymindset.wordpress.com/2015/04/01/marvel-announces-squirrel-girl-and-howard-the-duck-team-up-movie/ crossover movie]]. The previous year, they renamed themselves "The American Mindset" for the day and posted an article about [[https://mickeymindset.wordpress.com/2014/04/01/the-most-patriotic-disney-moments-in-history/ their favorite patriotic Disney moments.]]
* Website/{{Neopets}} has done this for over 10 years:
** 2000: A page filled with [[http://www.neopets.com/badpets.phtml pets that didn't quite make the cut]]. (The artists were having a bad day.)
** 2001: An announcement that some of the pets would be [[http://www.neopets.com/makeover2.phtml redesigned]].
** 2002: The Pant Devil stole everyone's items, including ones in their Safety Deposit Boxes.
** 2003: A sneak preview of the site's TotallyRadical makeover, [[http://www.neopets.com/index_fake.phtml Neopetz]].
** 2004: A new TCG expansion pack, "Quiguki Armageddon". It featured a parody of their Usuki toys, called Quigukis (based on the frog-like Quiggles). The Quigukis underwent {{Defictionalization}}, everything else did not.
** 2005: [[http://www.neopets.com/possiblepets.phtml 50 new Neopets]], with the announcement that the maximum number of pets an account could have was now 10 (instead of 4). A poll was held, and the most popular (the Lamameeah) was released as an actual Neopet (the Gnorbu), while a few others were released as Petpets.
** 2006: To stabilize the Neopian economy, [[http://www.neopets.com/neocharge/help.phtml NeoCharge]] was introduced, which taxed users for each page they visited. Failure to pay debts would supposedly result in accounts being flagged, and actions being taken to "compensate" [[note]]Losing items, pets being put up for adoption or returned to a basic color, restricted access to the site, more ads, etc.[[/note]].
** 2007: The Battledome was closed, as well as the Battledome section of the forums, and any weapon shop.
** 2008: The [=NeoBuddy=] system was introduced, where a questionnaire would match you up with a buddy (Bug Eye [=McGee=] for most, Sir Fufon Lui for a few), [[StopHelpingMe who would pop up from time to time and give advice]].
** 2009: It was announced that the pets would be phased out in favor of [[http://www.neopets.com/neoplants.phtml Neoplants]], and there were minor jokes around the site as well:
*** The Hidden Tower was closed until further notice, as was the Faerieland Employment Agency.
*** The Tiki Tack Tomobola was perpetually out of money, and kept asking for a 1 NP donation.
*** Neopoint inflation rose tenfold, and interest rates at the Bank were lowered (the Banker got a new appearance, as well).
*** The Stock Market was stuck; no prices moved up or down.
** 2010: More minor jokes:
*** The Battledome: ''In 3D!'' [[http://images.neopets.com/trousers/video/bd3d1.swf]] [[http://images.neopets.com/trousers/video/bd3d2.swf]] [[http://images.neopets.com/trousers/video/bd3d3.swf]]
*** The Prank Warehouse opened up, which allowed users to send various pranks (such as pies or slime) to their friends.
*** Neoboard filters were added-- for instance, "3.14" would be changed to "numbers", "snot" would be filtered into "faerie dust", and [[TakeThat/{{Other}} "slime" would be changed into]] "''Literature/{{Twilight}}''"
*** They also snuck one into their {{Facebook}} page, with some concept art-- of the "[[{{Squick}} Meat Faerie]]".
* [[http://www.sydlexia.com/ SydLexia.com]] posted [[http://www.sydlexia.com/top100vb.htm the 100 Best Virtual Boy Games Ever]]. It's obvious that the overall number of [[OtherNintendoSystems Virtual Boy]] games is nowhere near that number. ''Virtual Boy VideoGame/WarioLand'' was the only game listed, and in all 100 spots too, no exceptions. Reading the commentaries, they seem to claim that there are many versions of ''Virtual Boy Wario Land'', even versions for different consoles, all with the same title. Some of the comments were ripped directly from the prior Top 100 lists Syd had made. There were even surprise comments from [[Film/{{Labyrinth}} Jareth The Goblin King]] and AvrilLavigne.
* [=ToughPigs=], a fansite of Franchise/TheMuppets, has done this almost every year since 2008.
** In 2008, they temporarily converted to a [[http://www.toughpigs.com/toughpigs-com-topo-gigio-fans-who-grew-up/ Topo Gigio fansite]].
** In 2009, [[http://www.toughpigs.com/april-fool/ their joke]] was a bit more [[{{Pun}} "negative"]] than the previous year.
** In 2010, when ''Film/TheMuppets'' was still in its preproduction stage, they posted a [[http://www.toughpigs.com/muppet-movie-remake/ newsbit]] about the movie actually being a remake of [[Film/TheMuppetMovie their first film]]. TheyChangedItNowItSucks reactions ensued.
** In 2012, the site renamed itself [[http://www.toughpigs.com/toughbears/ ToughBears]] and posted a total of seven fake articles relating to Muppet bears, such as an app of Flo Bear from ''Series/SesameStreet'' (which is said to consist of a looping animation of Flo writing a book), Bobo starring in a Judd Apatow film, and a countdown of the top 100 Emily Bear moments (of which there are only three listed; the article teased that the other 97 would come soon).
** In 2013, they [[http://www.toughpigs.com/switcheroo/ switched duties]] with fellow Muppet fansite The Muppet Mindset. [=ToughPigs=] proved to be more active in that regard, with spoofs of all of the Mindset's regular articles such as "Weekly Muppet Wednesdays", "The Great Muppet Survey" and "Muppet Fan's Muppet Collection Chronicle". Meanwhile, the Mindset went with the [[https://muppetmindset.wordpress.com/2013/04/01/the-muppet-mindset-beautiful-toy-pageant-2013/ "Beautiful Toy Pageant"]] (a spoof of TP's regular [[http://www.toughpigs.com/tag/ugly-toys/ "Ugly Toy Pageant"]]) and a now-removed article called "My Week With Marilyn" (''very'' loosely inspired by TP's [[http://www.toughpigs.com/category/my-week/ "My Week With..."]] review series).
** In 2014, during the wake of ''Film/MuppetsMostWanted'''s release, [=ToughPigs=], the Muppet Mindset and another fansite called Muppet Stuff, had that movie's main villain Constantine take over their sites. However, TP gets bonus points for ''[[https://www.youtube.com/watch?v=tR5ZFvnBE-o having Constantine's puppeteer Matt Vogel record a special message for the site]]''. Throughout the day they [[http://www.toughpigs.com/constantine-takeover/ posted all sorts of articles]] relating to the then-recent film, including one about the Muppets doing a concert appearance at Carnegie Hall, modeled after the ones they did in the film. (Note: Some of the articles relate to ''very'' specific events in the film, and they might not make much sense to those who haven't seen ''Muppets Most Wanted'', so spoiler alert!)
** 2015: The site rebranded itself into "[=BuzzPigs=]", with over a dozen articles about the Muppets written InTheStyleOf [=BuzzFeed=]. Many of them were trolling articles - one of them, about how to be a true Muppet fan in New York City, recommended doing all sorts of ridiculous things referencing ''Film/TheMuppetsTakeManhattan'', the last of which was to ''walk directly in the path of an oncoming cab''[[note]]Kermit had done so in the movie, giving him EasyAmnesia[[/note]]. The quizzes were just as ridiculous - for the "Which Muppeteer Are You?" quiz, your result would always be "[[EskimosArentReal Puppeteers Do Not Exist.]] The Muppets are real. Please share this result with your friends. Sincerely, [[ExecutiveMeddling The Walt Disney Company]]." They also boasted that they could guess your favorite Muppet. The result would always be Mildred Huxtetter (a slightly obscure Muppet rarely seen since ''Series/TheMuppetShow'' ended).
*** Notably, one of their "Muppet facts you definitely didn't know because I made them all up" was that [[Series/FraggleRock Junior Gorg]] performed the wedding of two Fraggle crew members on the set, which has a bit of truth mixed into it - Richard Hunt, who voiced Junior, was the "minister" for fellow Muppeteer Jerry Nelson's wedding in RealLife.
* The B-movie review site [[http://www.stomptokyo.com Stomp Tokyo]] reviewed nonexistent movies on 1 April. The first of these was ''[[http://www.stomptokyo.com/movies/dellon-godhead.html The Dellon Godhead]]'', a ''Series/DoctorWho'' / ''[[Series/TheAvengers The New Avengers]]'' crossover, supposedly including BrianBlessed as a football-obsessed Blackbeard.
* Website/{{Tumblr}} debuted an "Executive Suite 2015", complete with spreadsheets, a notepad, and a calculator (which didn't work). Also, if you tried the "free trial", your blog got a business-esque addendum to its name, and your dashboard was overrun by a "helpful" Clippy-esque icon: A copy machine named Coppy which you couldn't get rid of (clicking its X caused it to go away for about 3 seconds before it popped up again). Coppy subsequently became an EnsembleDarkhorse among users.
* In 2015, Website/{{Twitch}} made the infamous "Kappa" emoticon become a question-mark silhouette when used in chat. How do you get the actual Kappa emote? [[AscendedMeme By typing "Grey Face" with no spaces]].
* From 2005 to 2009, [[http://www.vgmaps.com/ VGMaps.com: The Video Game Atlas]] used to feature maps for fake video games. In order, these are [[http://www.vgmaps.com/NewsArchives/MapsOfTheMonth-2005.htm#04 The Legend Of Zelda: Link's Awakening Advance]], [[http://www.vgmaps.com/NewsArchives/MapsOfTheMonth-2006.htm#04 Mega Man Solid X: Guns Of The Mavericks]] (solid-x.com links dead), [[http://www.vgmaps.com/NewsArchives/MapsOfTheMonth-2007.htm#04 Super Kid Icarus]], [[http://www.vgmaps.com/NewsArchives/MapsOfTheMonth-2008.htm#04 The Legend Of Zelda: Oracle Of Hours]], and [[http://www.vgmaps.com/NewsArchives/MapsOfTheMonth-2009.htm#04 Metroid Dread]].
* The WizardsOfTheCoast message board has had some good ones. One instance that sticks out is having everyone's avatar switched with one of the My Little Pony pictures. It quickly got out of hand when people who linked to their wizards avatars on other message boards saw the change, and thought the Wiz_0's(mods) were following them.
** They also once announced a Mattel merger between My Little Pony and Dungeons and Dragons. The pink beholder graphic with bows on its eyestalks remains iconic...
* Website/YouTube runs regular April Fools' Day pranks.
** 2008: During the height of the {{rickroll}}ing craze, [=YouTube=] linked every front page video to the infamous Rick Astley song. [[http://www.kongregate.com Kongregate]] pulled a similar trick.
** 2009: [=YouTube=] took a page from ''WebAnimation/HomestarRunner'' and flipped the site (and videos!) upside down. This lasted even beyond the date itself with a URL suffix. However, it didn't always work (For example, if you're using a [=YouTube=] userscript for the Greasemonkey add-on for Firefox.) Some videos also weren't completely fixed afterward and will flip upside down when put into high quality.
** 2010: [=YouTube=] put a "text-only mode", displaying certain videos as entirely made of text in various colors--including nearly any video with resolution greater than 360p, not just videos Youtube had done manually. This effectively made [[AsciiArt Ascii Shading Art]]. Sadly, it's long gone, and not even available by URL anymore. There also was a cat (who you may know as [[{{Lolcat}} Ceiling Cat)]] peeking through the video processing icon. [[http://www.youtube.com/watch?v=jGF9vAEhRFI See it here.]]
** 2011: [=YouTube=] had a [[http://www.youtube.com/watch?v=CNm8ZCJ7Fx8 1911 mode]], claiming to be videos made in 1911, including "[[TheAnnoyingOrange The Irksome Citrus]]", "[[ScreamerPrank Horse & Buggy Crash]]" (wherein one is [[{{Rickroll}} Ruth Roll'd]]), and "Flugelhorn Feline". The videos are in sepia while old-time music plays over the audio. With intertitles in modified AntiquatedLinguistics (Alert. We have a fornicator in Lincoln Heights!"). Viewers delighted in leaving comments written in the same style.
** 2012: [=YouTube=] brings out "The [=YouTube=] Collection", where you can purchase [=YouTube=] in its entirety, packaged and shipped to you in a convenient 100,000-disc collection!
** 2013: [=YouTube=] is finished! That's right, it's now time to choose the best [=YouTube=] video ever, so the site is shutting down, and going to spend the next ten years reviewing ''every single video'' on the site to pick the best one. The winner will recieve [[UndesirablePrize a $500 stripend for their next creative endeavor and an MP3 player that clips to your sleeve]]. This prank culminated in a roughly [[http://www.youtube.com/watch?v=HGeMGqVKD6A twelve-hour live stream]] consisting of two announcers [[OverlyLongGag reading out the names and descriptions of the nominees]] (read: any possible random video on the site), fraught with [[StylisticSuck technical difficulties]] and ending with about fifteen minutes of the announcers [[RefugeInAudacity sleeping it off]] without [[{{Anticlimax}} any real conclusion]].
** 2014: [=YouTube=] put up a video claiming they were responsible for all the world's most popular viral videos, announcing the "[[ForcedMeme new trends]]" for viral videos in 2014: "Clocking", "Kissing Dad", and the "Glub Glub Water Dance". Other trends were announced, including "Getsyburg Addressing", "Cake-Bumping", "Nap-Cams", "Geology", "Wolf-Mask Tee Ball", "The Harlem Shake (Again)", and "1000 Dollar Gifting".
** 2015: [=YouTube=] decides to cash in on the [[MemeticMutation "Darude - Sandstorm"]] craze for 2015's April Fools Day. The video bar for all videos had an "Add Music" button added to it which, when clicked, played one of four snippets of Sandstorm. Also, most if not all search results had "Did you mean: [[DepartmentOfRedundancyDepartment Darude - Sandstorm by Darude]]" at the top.
* Creator/AmbrosiaSoftware released a free program called ''[=ScreenCleaner=] Pro'', which claimed to be able to fix up monitors by brightening them; you opened the program, waited a few minutes while it "calibrated", and then the monitor would brighten significantly. Apparently a miracle product... except what it ''really'' did was gradually darken the screen, then turn it back to the original brightness. They even went so far as to get a fake positive review from a software site to make it look legitimate.
* ''Literature/TalesOfMU'' posted an [[http://www.talesofmu.com/story/uncategorized/big-news update]] in 2009, announcing production plans for a SyFy channel spin-off TV show, of which the author claimed pride but apparently had little creative control, resulting in significant deviations from the core themes of the novel. It linked to the writer's Livejournal crossposting, where comments revealed the prank. A few commenters disbelieved the announcement because it referenced "the newly branded SyFy channel" at the end, and were double-pranked to discover SciFi's renaming on April 1st, though it was widely known earlier.
* The {{Defictionaliz|ation}}ed Digibutter.nerr once claimed to be bought out by 4Kids. Every forum but the Party, Off Topic and RP forums were locked, and people took on parody alts that made fun of various characterizations and dubbing errors.
** And a year later, they changed their name to the "Bitlands" (a spin-off site from it already exists) for April 1, 2010. Then it was revealed that there WILL be a name change and it MIGHT be the Bitlands anyways.
* In one of the most cruel examples imaginable [[RuleThirtyFour that one porn site]] enacted an April Fool's joke resulting in the ban of all lolicon/shota artwork from the site. What makes this particularly nasty is the joke was cooked up in response to e-hentai's ACTUAL ban of all underaged artwork due to MoralGuardian antagonization of their advertisers, and used the subpoena sent to them as the excuse, doctored up to look like it was sent to [[RuleThirtyFour said pornsite instead.]] The joke was meant to be incredibly obvious, as the featured image was Rugrats (with, at one point, a feature change to Popeye dressed as Sailor Moon in response to an anonymous commenter along with the comment 'But older characters cosplaying as underaged? Yes that's still acceptable.'), however due to the e-hentai debacle, users just couldn't believe it was a joke and [[{{Wangst}} some serious debate went down over the state of the world and continuing persecution of lolicons.]] Some artists even [[BerserkButton ragequit over what they took to be impending censorship of their art on a site that shouldn't have it.]] All staff were told to keep up appearances for a day after, duplicate pics that were to be deleted were saved up for about a week prior, then commented upon before being deleted to lend to the authenticity. A few artists still haven't returned, and probably never will.
** And then to top it off, e-hentai ''unbanned'' underaged artwork, instead placing it on the spin-off site exhentai.
* On podcast ''[[http://www.allmovietalk.com All Movie Talk]]'', in the intro portion for the last Tuesday before April Fools' Day:
** Sam told listeners that the episode contained the word "movie" more times than any other episode, and encouraged listeners to verify this (true or no, that's a lot of time to be counting the word "movie");
** Stephen claimed to have gotten everyone a gift...only to reveal that it was a free movie podcast (just like every week);
** Sam listed off the segments for the episode (which were false);
** and finally, they introduced themselves as each other.
* [[http://www.wcnews.com Wing Commander CIC]], a Videogame/WingCommander online fandom news site, changes the main site's look to something silly on April 1st, and posts "news" articles that are loaded with {{take that}}s, at [[TakeThatMe themselves]] and others, often along with joke announcements of fictional new WC releases.
* [[{{Speedrun}} TASVideos]] gets many joke run submissions during April Fools' day. Sometimes the joke is the game, as in the submissions for ''Color a Dinosaur'' or ''[[VideoGame/PennAndTellersSmokeAndMirrors Desert Bus]]''. Sometimes the run is the joke, as in the ''VideoGame/TheLegendOfZeldaTwilightPrincess'' [[http://tasvideos.org/3515S.html run]] that would ''crash the game and make it load another emulator from the emulated console's SD card''.
** One infamous AprilFoolsDay joke was half-serious: they actually had discovered that emulators can never properly replicate certain forms of randomness used by the actual hardware, but they didn't ''really'' intend to shut down the whole site over it.
*** Ironically, since then, emulator runs have actually been proven to [[http://tasvideos.org/ConsoleVerifiedMovies.html run on console]], depending on the game.
** The site itself also does April Fools' jokes, such as in 2014 when they announced [[http://pro.tasvideos.org/ TASVideos Pro]], "a place where only the most professional [=TASers=] contribute the truly best runs" available for [[BribingYourWayToVictory only $25 USD a month]].
* Ponibooru (a Danbooru-like image website for ''WesternAnimation/MyLittlePonyFriendshipIsMagic'') became overrun by Pinkie Pies during April Fools' 2012.
** In 2013, its successor site Derpibooru got in on the act by converting into [[EnsembleDarkhorse Trixie]]booru for April Fools' Day.
** 2014 saw Derpibooru replace the background behind each image thumbnail with a randomized image of Creator/NicolasCage, as well as renaming the anonymous "Background Pony" title after him.
** In 2015, the site was flooded with Desktop Ponies.
* Like with the actual game, the VideoGame/TeamFortress2 official wiki has been doing April Fools' Day pranks since 2011, as seen [[http://wiki.teamfortress.com/wiki/Team_Fortress_Wiki:April_Fools%27_Day here.]]
** On April 1st, 2011, the Team Fortress Wiki altered the front page as part of a fictional '''Australium April Update'''. The "featured article" rotated between the pages for the new class, the [[Memes/TeamFortress2 Demopan]], and the new Cow melee weapon for the Heavy. The Demopan page was originally created by Benjamuffin for his user page, while the Cow page was created specifically for April Fools' Day by Focusknock. The trending topics were changed to Cow, Demopan, Frying Pan, Bounty Hat, Chargin' Targe, Dangeresque, Too?, Stout Shako, and For 2 Refined (which links to the Trading page) for the day. A fake update post, written by Stevoisiak, was added to the current events describing the fake update.
** For April Fools' Day 2012, [[http://wiki.teamfortress.com/wiki/April_1,_2012_Patch a fake patch article was released]] announcing [[http://steampowered.wiki.tf/app/900 the release of Ricochet 2]], along with the addition of the following items: the [[http://wiki.teamfortress.com/wiki/Circular_Circlesaw Circular Circlesaw]], the [[http://wiki.teamfortress.com/wiki/Crocketeer%27s_Cloak Crocketeer's Cloak]], the [[http://wiki.teamfortress.com/wiki/Ricochest Ricochest]], and the [[http://wiki.teamfortress.com/wiki/Heartwarming_Headache Heartwarming Headache]]. Apparently, this joke was so good, [[http://oxcgn.com/2012/04/02/valve-begins-ricochet-2-pre-orders-on-steam/ some people thought Valve was behind it]], even though Valve was not involved in any way in this update; everything has been thought of and created by Wiki editors. More info can be found [[http://wiki.teamfortress.com/wiki/Team_Fortress_Wiki:April_Fools%27_Day/2012 here.]]
*** What's interesting about this April Fools' Day prank (which may or may not be coincidental and/or {{foreshadowing}}) is that it promised "native client support for Linux", [[http://www.teamfortress.com/post.php?id=9955 which did eventually get added to the game]] (at least on Ubuntu).
* On April 1st, 2013, thepiratebay.se posted a [[http://thepiratebay.se/blog/230 blog post]] informing that their servers have been changed from North Korea to the United States and that all torrents from North Korea, China, Iran, France and [[{{Qurac}} Islamistan]] would be removed.
** On April 1st 2014, the site introduced "The Virtual Bay", where "you'll be able to see, hear and feel everything that is a part of The Pirate Bay."
* For 2013, the FanTranslation group Absolute Zero released an English translation patch for ''VideoGame/TalesOfTheTempest'' - a game which most fans of the series consider to be complete shit (the readme even goes into detail about how terrible the game is).
* In April 1st, 2013, the Website/{{Reddit}} blog [[http://blog.reddit.com/2013/04/reddit-buys-team-fortress-2.html stated]] that Reddit has bought ''VideoGame/TeamFortress2''. The [=TF2=] blog, however, [[http://www.teamfortress.com/post.php?id=10307 stated]] that Team Fortress 2 has secretly bought Reddit instead.
** With the taking over of ''VideoGame/TeamFortress2''/Website/{{Reddit}}, Reddit hosted a voting competition between Orangered and Periwinkle,(Read: Red and Blue) and whoever got the most hats, another addition of the site, won. If you care, then [[spoiler:Orangered]] won.
** In 2013 the Subreddits for ''Franchise/StarWars'' and ''Franchise/StarTrek'' switched backgrounds for the day. Two years later, ''Webcomic/{{Homestuck}}'' and ''WesternAnimation/StevenUniverse'' did the same thing. Both left a lot of fans scratching their heads.
* On April 1, 2014, Creator/{{NPR}}'s website ran an article titled [[http://www.npr.org/2014/04/01/297690717/why-doesnt-america-read-anymore "Why Doesn't America Read Anymore?"]], an example of a prank meant to prove a point. The comments section is filled with people who, uh, proved NPR's point.
* Though they uploaded the video a day early, WebVideo/CinemaSins pranked its audience in 2014 by making a "What's the Damage?" video for ''Film/{{Titanic}}''. It was a 10+ minute long video... [[spoiler:that was over in 30 seconds. One (1) Titanic: $7.5 million 1912 dollars. The rest of the video is mostly a black screen, sprinkled with a few of the usual funny bits.]]
* In 2012 LoadingReadyRun announced that they would be renaming their site to [="CatingCattyCats"=] to produce exclusively cat-related content for a Chinese company as part of a corporate takeover.
-->"They offered us just a shitton of cash,” said Graham Stark, President and co-founder of LoadingReadyRun Megacorp Inc. “Like, you think you can imagine a shitton of cash, but you really, really can’t. We’re very excited to work with [=MauBau=], the market leader of cat-focused entertainment content, to create great new entertainment properties. [[SellOut Also to get their money]]. Of which there is a shitton."
* In 2012, Grooveshark (a music streaming website) introduced a new feature where [[{{Hipster}} Hipster Otis and Hipster Jen]] pop up to offer inane commentary on any song you play.
* On April 1, 2012, instead of an ''{{Literature/Animorphs}}'' review, ''Blog/CinnamonBunzuh'' surprised everyone by releasing a review for StephenieMeyer's ''Literature/TheHost''. Except when one actually clicks the review, it consists of nothing but an Andalite troll smiley (which bizarrely actually works) and a note:
-->''"This book is really long, and we are lazy. Sorry folks!"''
* In April 1st 2009, {{LetsPlay/Chuggaaconroy}} did an intentionally poor LetsPlay of ''VideoGame/MegaMan2'', as a parody of all the bad [=LPs=] the game was receiving.
** In April 1st, 2011, he posted a Tweet that stated that his 14th LP would be ''VideoGame/{{Pikmin}} 2''. His 14th LP was actually ''LuigisMansion'', but his 15th LP, starting the day after ''Luigi's Mansion'', WAS ''Pikmin 2''.
* angelarts's VA LetsPlay of ''VideoGame/EarthBound'' [[http://youtu.be/0P4BUZxUbEY was updated]] in April 1st 2013 stating that it was canceled. [[http://youtu.be/6qDVuOKGX5g An additional video]] was added later that day stating that it was, indeed, an April Fools' Day joke.
* LetsPlay/SomeCallMeJohnny released a [[https://www.youtube.com/watch?v=jPoyXt6OPnw ridiculously over the top review]] of ''VideoGame/SonicTheHedgehog4: Episode I'' on 2010.
* On 2013, two blogs by sports-related cooks - a serious one and a CordonBleughChef - [[http://kissingsuzykolber.uproxx.com/2013/04/leftover-easter-candy-the-football-foodie-offseason.html switched ]][[http://www.sbnation.com/2013/4/1/4170160/spilly-final-four-meal-hey-this-looks-good places]].
* For 2014, instead of pranking their visitors, ''Website/{{Cracked}}'' instead created an infographic containing "[[http://www.cracked.com/quick-fixes/13-shocking-statistics-you-wont-believe-are-true/ 13 Shocking Statistics You Won't Believe Are True]]" for their readers to post on their Facebook/Tumblr/Twitter to see how many people will share them [[spoiler:without first verifying how [[BlatantLies ridiculously false]] the facts are]].
* On April 1st 2014, the Fine Brothers [[http://www.youtube.com/watch?v=VSpFRcTeUQ4 premiered a new segment]] on their WebVideo/{{React}} series. The subjects? [[spoiler: Cats, of course.]]
** A fair few popular YouTubers also made April Fool's videos in 2014. The GameGrumps made Cat Grumps and Meow Train, two new segments [[spoiler: also starring cats]], cobanermani456 announced [[https://www.youtube.com/watch?v=NlXIiABNP40 a playthrough of Shadow the Hedgehog]] [[spoiler: (while the video was indeed a joke, he eventually [[SubvertedTrope gave in and made a legitimate playthrough of the actual game]])]], [=SethBling=] announced ''VideoGame/{{Minecraft}}'' snapshot 14w14a [[spoiler: which turned out to be a Bukkit plugin]], etc.
* ''[[WebVideo/PBSIdeaChannel Idea Channel]]'':
** 2013: [[http://www.youtube.com/watch?v=jYrmlgiv8eM "Is Vine The Future of Cinema?"]]
** 2014 [[https://www.youtube.com/watch?v=00vL3QYVyLY "What Does IKEA Say About The Human Condition?"]]. This was eventually made into a real episode called [[https://www.youtube.com/watch?v=xJ9tDuPHirE "SRSLY What Does IKEA Say About The Human Condition?"]]
** 2015: [[https://www.youtube.com/watch?v=YmBTORj6mJA "What Does The Chunnel Day About Europeon Diplomacy?"]], which is just [[spoiler:footage of the chunnel leading to the ''Idea Channel'' logo and Mike giving a brief message at the end.]]
* April Fool's is the only holiday Creator/TheMidnightFrogs celebrate every year, making parodies of something different each time. Thus far they've "abridged" paper, a wedding video, the short film version of Literature/{{Crash}}, the first episode of Anime/SonicX, and they switched the character voices from the first episode of their ''WebVideo/SgtFrogAbridged''.
* In 2013, WebVideo/RhettAndLink posted a video on their [=YouTube=] channel entitled "[[https://www.youtube.com/watch?v=TCepmG00VHk Funny Baby Panda Kiss]]", promising [[ExactlyWhatItSaysOnTheTin just that]]. It ends up being an ad. Click the Skip button and you get... ''another'' ad. Click it again, and you see the duo hyping up the video that you're [[TheUnreveal never going to see]].
* ''I'm Moving to Alaska'' by [[WebVideo/MatthewSantoro Matthew Santoro]] turned out to be this. Matt said that he would move to Alaska the next day, for reasons like riding seals and whales for the entertainment of Eskimos, running around with polar bears, and freezing. To his surprise, some people fell for this.
* WebOriginal/{{Chrontendo}} said once that he was going to review every game released for the Philips CD-I on 1 April 2012. A day later, he posted [[https://www.youtube.com/watch?v=-67BV7mJ5LI this video]] and people started to realize that he was joking.
* The music Database Encyclopedia Metallum has a tradition of pulling these every year since 2009, only having not participated once - in 2011.
** The first prank saw the site accept the nu-metal band Music/{{KoRn}} into it's database, after the mods deemed the band's first album to be "metal enough".
** 2010 saw the removal of the site's forum, the Tavern, for a day.
** In 2012, the site posted an FBI logo on it's main page, suggesting that it had been taken down due to promoting internet piracy. Despite the fact that you simply had to click just to get to the main page, many people feared the site had suffered the same fate as MegaUpload.
** 2013 saw the addition of Music/{{Nickelback}} to the site, in the same vein as the addition of KoRn. It was accompanied by several reviews praising the band's albums, as well as numerous vandalisms of the band's page (for example: It was stated that Hellblazer, one of MA's founders, was actually Chad Kroeger). The satire site Tyranny of Tradition expanded upon this by running a fake article having Nickelback supposedly hold a press conference in response to the site.
** 2014 had 2 pranks:
*** The first being the vandalism of the page for a Chilean Black Metal band named Hades Archer, having their genre of music changed to "Penis Metal".
*** A secondary prank involved the deletion of the page for the controversial band Music/{{Meshuggah}} (whose genre was listed as "Technical Nu-Metal/Djent"), as well as several staged arguments between the moderators.
* WebOriginal/BadCreepypasta: On April 2014, the crew did a reading of the ''WesternAnimation/{{My Little Pony|FriendshipIsMagic}}'' fanfic "{{FanFic/Cupcakes}}", expect they were reading off a baking recipe for cupcakes.
* On April 1 2014, the [[http://harrypotter.wikia.com Harry Potter Wiki]] became the "Lord Voldemort Wiki".
* On April 1 2014, Brixton Buzz announced that [[http://www.brixtonbuzz.com/2014/04/brixton-to-be-renamed-east-clapham-under-forthcoming-rebranding-policy/ Brixton was to be renamed East Clapham]].
* On April 1 2014, and for about two weeks afterwards, Coasterpedia (the Wikia one) had an article on the "Creator/RiverPhoenix", which was "a flair-loop coaster installed in the grounds of the Creator/ParisHilton".[[note]]"flair loop" is of course an anagram of "April fool"[[/note]]
* ''Website/HardcoreGaming101'', on April 1, 2015, presented a "Your Weekly Kusoge" review of ''VideoGame/FinalFantasyVI''.
* In 2014 and 2015, ''Wiki/SuperMarioWiki'' featured strange, but true facts about the Mario universe out of context. One example from 2015 was a line from [[MemeticMutation the infamous Navgtr review of]] ''VideoGame/DonkeyKongCountry'': "Donkey Kong Country is truly perfect. If you do not get this amazing new generation of Donkey Kong madness, you are stupid. Yes, we know it's insulting, but that's also the truth. If you're a true video game fan, you will not hesitate in the slightest bit to buy this piece of gaming history."
** Other members of NIWA have done the same. ''[=SmashWiki=]'' featured fake Smash Bros news in 2014, and in 2015 changed their name to ''[[PunnyName Smash]][[VideoGame/{{Xenoblade}} Riki]]''.
** The ''VideoGame/DonkeyKong Wiki'' changed their name to ''[[VideoGame/DonkeyKong64 Lanky Kong Wiki]]'' in 2015.
** In 2014 and 2015, the ''VideoGame/AnimalCrossing Wiki'' had a banner claiming the wiki would be shutting down, with a link to their article on April Fools' Day.
* In 2015, Website/NotAlwaysRight made all of their stories about a fictional ZombieApocalypse. This was also used on their sister sites, including Website/NotAlwaysWorking.

[[folder:Web Video]]
* Many of the people at [[Website/ThatGuyWithTheGlasses Channel Awesome]] love to do at least one per year.
** [[WebVideo/AtopTheFourthWall Linkara]]:
*** In 2011, Lewis put up three separate videos: a review of ''Titans #23'' that was literally just Linkara saying that the comic sucked, a review of ''ComicBook/OneMoreDay'' done by his [[CompanionCube teddy bear]], and a review of a Franchise/PowerRangers comic done in the style of WebVideo/TheIrateGamer.
*** In 2013 he uploaded a video titled "Frankenstein Meets the Space Monster," which first starts with Linkara stating he's going to review a novelty lamp he got at a store. The video then cuts out, and when it comes back we suddenly see Linkara imitating the WebVideo/TheCinemaSnob, and doing a review of the aforementioned movie.
*** In 2014 he uploaded an episode of Mobile Suit Gundam Abridged, but the Blip thumbnail and description have it labeled as a new HistoryOfPowerRangers update (as this series has become notorious for how long it takes for Linkara to update it, some videos even being uploaded an entire year apart) Made slightly more obvious in that the 'update' was for the Mighty Morphin movie, which he already established years ago he would not review.
** Doug Walker:
*** In 2009, Doug's three main characters switched series for an episode. WebVideo/TheNostalgiaCritic had to answer questions meant for [[WebVideo/AskThatGuyWithTheGlasses Ask That Guy]], Ask That Guy had to do a review of ''WesternAnimation/MonstersVsAliens'' in style of [[WebVideo/BumReviews Chester A. Bum]], and Chester had to do a review of ''Film/TheNeverendingStory'' instead of the Critic.
*** For 2014 instead of one of his usual ''WesternAnimation/AdventureTime'' vlogs, he instead uploads a vlog where he and Jason end up confusing the first episode of ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' for an Adventure Time episode.
** ToddInTheShadows:
*** In 2014, his [[http://thatguywiththeglasses.com/videolinks/teamt/tis/one-hit-wonderland/42800-float-on "Float On"]] One Hit Wonderland video first seems like it's going to be about the Music/ModestMouse song, only to then instead be about a similarly named song by a '70s R&B group called "The Floaters."
** Creator/BradJones:
*** His 2014 joke was to upload a new video to the ''WebVideo/DVDRHell'' section of the site, making it look like he's going to review the infamous ''Film/TheDayTheClownCried''. Instead the video turned out to be [[WebVideo/BradJonesDemoReel a parody]] of ''WebVideo/DemoReel'', a web series by Doug Walker that suffered MagnumOpusDissonance.
* The April 1 episode of ''WebVideo/MaddMan'' was not in fact about John Maddaloni trying to do a stunt and looking lame, but actually a fake trailer for a melodrama with hand puppets. Well, not puppets, just hands...[[http://www.youtube.com/watch?v=R3Mim6mvqmo it's easier if you watch for yourself.]]
* ''WebVideo/TVTrash'' put up a review of RealityTelevision... [[spoiler:consisting of him yelling, "IT SUCKS!", walking away, the closing credits, and ten minutes of a black screen]].
* ''WebVideo/{{Unskippable}}'': As a preemptive April Fools' Day joke, Graham and Paul's March 30, 2010 video promised to riff on ''VideoGame/FinalFantasyXIII'', and instead featured "[[VideoGame/FinalFantasyVI Final Fantasy III]]". "How much difference can one X make?"
* WebVideo/{{Vinesauce}} had a good one in 2015: Joel did his entire stream for that day in his native language (Swedish). He also messed around with Google Translate, translating English phrases into different languages and trying to say a few in Japanese.
** Vinny, meanwhile, streamed ''VideoGame/TomodachiLife'' with a few... alterations. [[spoiler:Namely, three less active islanders were [[AssimilationPlot replaced by Jahns offscreen]], and [[TheFourthWallWillNotProtectYou Vinny himself acted as if they assimilated him as well.]]]] However, this likely wasn't a prank, given that [[spoiler:he still saved the changes]]... Either way, [[WhamEpisode fans freaked out.]]
* ''WebVideo/WatcherOfThe2000s'' had a gag on April 1, 2014, where a review for ''Film/DragonBallEvolution'' was disguised as a review for ''Film/TheWatcher'', a movie that resembles the name of the series.
* Romhack website Romhacking.net put up a link on April 1, 2014 for a translation of Etrian Odyssey Retold, a supposed "hard version" of VideoGame/EtrianOdyssey. [[spoiler:It was actually a full translation for the game 7th Dragon.

[[folder:Western Animation]]
* Creator/CartoonNetwork:
** In 1997, they ran the ''ScrewySquirrel'' cartoon "Happy-Go-Nutty" repeatedly for twelve hours straight. The network's AOL site (this was a year before [=CartoonNetwork.com=] launched) ran banner messages saying that Screwy had taken over the network and was making demands with the authorities. The banners read "April Fools" after the madness ended after 6pm.
** In 2009, they replaced the majority of their programming with a surprise ''WesternAnimation/CowAndChicken''[[note]]which hadn't regularly been aired on the main network for years[[/note]] marathon.
** In 2010, they added fart and belch sound effects to almost every cartoon they aired throughout the day, even to the intros.
** In 2011, the logo but at the bottom of the screen was flipped upside-down.
* Infamously done with ''WesternAnimation/SouthPark''[='=]s season 2 premiere in 1998; the audience was expection a resolution to Season 1's CliffHanger about who Eric Cartman's father was, but instead they got an episode dedicated to the farting Canadian ShowWithinAShow Terrence & Phillip that aired on April 1st. Reactions from viewers were quite negative, leading to Trey Parker & Matt Stone resolving the cliffhanger in the season's second episode. This was later {{lampshade|Hanging}}d in the episode "Terrance & Phillip: Behind the Blow".
** It was also referenced in the 2010 episode "Eat, Pray, Queef" (which ALSO aired on April 1st), where the boys get mad after the conclusion to a 2-part ''Terrence & Phillip'' episode is replaced with a ''Queef Sisters'' episode. The creators actually originally intended to do a whole episode about the Queef Sisters, but went against it.
** Referenced again in the 2006 episode "Cartoon Wars Part 2", which pulled a similar "this episode will not be seen tonight" gag involving Terrence & Phillip. Which had its own Muhammad joke. That gets censored on its own. ...What? Are Terrence & Phillip arguing with the executive behind the edit now? And they bring up ''WesternAnimation/FamilyGuy'' showing Muhammad uncensored? And the executive is saying someone is probably going to FOX to stop them? Ah, now the episode ''truly'' begins...
* Creator/AdultSwim. 2012. While it began with the introduction to ''Film/TheRoom'' (which had been their joke in previous years), it quickly went in a different direction, bringing back {{Toonami}}[[note]]Canceled in September 2008[[/note]] for what was thought to be one night only. But then Creator/AdultSwim asked the fans what they thought on {{Twitter}}... They wanted their {{Toonami}}. As of May 26, 2012, they're getting it.
** 2004: Inuyasha. [[http://www.veoh.com/watch/v6555000RBbdbQSB?h1=Adult+Swim+2004+April+Fools-InuYasha+Mustaches moustaches]].
** Creator/AdultSwim did many things in different years, including doing the "add a fart track to all shows" that was later done on daytime Creator/CartoonNetwork, all the funnier because that was on Saturday Night that year, so they fart-tracked such series as ''Anime/GhostInTheShellStandaloneComplex''. One year, another Saturday, they replaced the anime lineup with ''PerfectHairForever''. In the year in which ''AquaTeenHungerForceColonMovieFilmForTheaters'' premiered, before the premier of the movie in theaters, they aired the entire movie on April 1st, but in a tiny block in the lower-right corner of the screen, without sound. One year, they dug up reruns of ''WesternAnimation/ChuckNorrisKarateKommandos''.
** In 2014, Adult Swim aired a new episode of PerfectHairForever alongside a ''WesternAnimation/SpaceGhostCoastToCoast'' marathon (one that included the uncut version of "Fire Ant", among other things.)
** For their April Fool's stunt in 2006 Creator/AdultSwim aired the Spumco short ''BooBooRunsWild'' rather than ''Anime/NeonGenesisEvangelion'' and inserted fart noises into ''Anime/FullmetalAlchemist''.
* In 2013, TeenNick advertised that they were planning to show a long lost episode of ''WesternAnimation/RockosModernLife'' at midnight as part of its Series/The90sAreAllThat block. Said episode was 30 minutes of Mayo from the "Wacky Delly" episode, followed by a showing of said episode to presumably clear things up for the numerous confused viewers born well after the time of ''Rocko'' passed.
* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'':
** In 2013, series writer Meghan [=McCarthy=] released a lot of false episode titles and synopses for season four. [[note]]401/402: "Wingin' It" (two-part episode), 403: "Now You Sea Them...", 404: "Meet Princess Skyla", 405: "The Student Becomes the Teacher: The Return of [[WesternAnimation/MyLittlePonyEquestriaGirls Sunset Shimmer]]", 406: "Luna-tic", Pinkie Pie becomes the Princess of Pie in the season mini-arc of 407: "Pinkie Apple Pie", 414: "Pie in the Sky", and 419: "Maude Pie", 408: "Don't You Dare" (Rainbow Dash threatens to leave the Daring Do fandom when they turn her hero into an Earth Pony.), 409: "It Ain't Easy Being Cheesy" (A musical episode guest starring Music/JustinBieber.), 410: "Oops" (Rarity is the star of a play but is replaced by AJ. Twi forgets and tells everypony RY is the star. Ponies are pissed.), 411: "Bats" It's just like the musical "Cats", but with, you know, bats. And ponies. But mostly bats.), 412: "The Return of the Return of Harmony" (Discord is back! And his new personality is kind of meh. Stupid writers), 413: "Wrap It Up" (Every loose end is tied up. Hilarity ensues when the ponies realize there are 13 more episodes to go.), 415: "Who Are You?" (Creator/DavidTennant guest stars as a random, nameless background pony no one has ever noticed before.), 417: "Just Forget It" (The [=CMCs=] try literally everything they can think of to get their Cutie Marks. They don't. The end.), 418: "Death Comes to Ponyville" (Didn't bother to read it. Was super busy that week. I'm sure it will be fine.), 420: "For Whom The Sweetie Bell Tolls" (cuz literary and makes us sound smart and stuff and, dude, is anybody else hungry?), 421: "It Ain't Easy Bein' Weezy" (a hilarious parody of Series/TheJeffersons. Look, they can't all be gold, people), 422: "Best Pony" (New pony comes to town and she's cool and likes craft beer and Legos and has a typewriter Cutie Mark), 423: "Spike and Rarity Sittin’ in a Tree" (Nothing happens. That would just make things weird between them. Plus, his ex is totally psycho.), 424: "Let the Games Begin" (Shining Armor and Cadance join the professional wife-throwing circuit. Destroy the competition.), 425/426: "Princess Discord" (2-parter in which Discord becomes a draconequalicorn and replaces Celestia. As she always intended.)[[/note]]
*** Notably some of these were actually correct (though with silly synopses). Since the existence of a forth Pie sister was already confirmed, many fans correctly guessed that "Maude Pie" was a reference to her.
** 2015:
*** Discovery Family released a promo for a side series called "[[https://youtu.be/IZArPt_x0CU Apple Bloomers]]", a MagicalGirl {{anime}} {{parody}} starring the Cutie Mark Crusaders. [[note]]A focused watcher may notice that it is scheduled for release Friday April 31st, but then you realize April doesn't even have 31 days.[[/note]]
*** Also in 2015, Andrea Libman tweeted that the show has been merged with ''{{Franchise/Transformers}}'', with Creator/MichaelBay set to direct it. The image tweeted is of Pinkie Pie (one of the characters she voices) in an Optimus Prime costume.
* Late in March 2015, the creator of ''WesternAnimation/KidsNextDoor'' linked to a Rainbow Monkey website that had a search bar. Various names from ''Kids Next Door'' could be entered into the search bar, which would return a single line answer. One term showed a countdown in strange alien numbers. Around the same time, a Galactic Kids Next Door video was uploaded on Website/YouTube; this video was apparently supposed to be shown when the countdown ended, but it was leaked. Strange messages from the original ''Kids Next Door'' voice actors suggested that some kind of revival was in the works. Problem was, the countdown would end on April 1st. Fans waited with baited breath to see what would happen when the countdown ended...and while a new video was released, it ended with the message "As of right now, there are no plans for a Galactic Kids Next Door Series. But...there ''should be''". It appears that the whole thing was part April Fool's joke, part ViralMarketing pitch.
* In 2015, ''WesternAnimation/StevenUniverse'' had a CrossOver with ''WesternAnimation/UncleGrandpa''. While it aired on April 2 (as to fit with the pattern of airing new episodes on Thursday), the episode itself says "April Fools'" in it. Part of the prank also included [[TrollingCreator one of the staff members]] considering it a {{Canon}} episode, though watching the episode, it is definitely not.

[[folder: Real Life]]
* Online tech news site TheRegister regularly put up joke articles on April 1st. The articles are usually gone by the next day however, although some of them are archived for posterity.
* China, notorious for their censorship regime, bans the media in the country from publishing or airing fake articles and reports on April Fools' Day.
* A popular joke is the "Fools' Day Parade", wherein someone announces a time and place and big acts for a parade that never happens. Some of the more entertaining press releases are of New York's "Annual April Fools' Day Parade", written by world-class prankster Joey Skaggs.
* British newspaper ''The Daily Mail'' pulled one a few years back by claiming (then-)Prime Minister Tony Blair had replaced the black door of 10 Downing Street with a red one.
* Many cable networks do April Fools' Day pranks. For example, Creator/AdultSwim will change their lineup or insert jokes into their programming: in 2005 it was fart jokes during {{anime}}; in 2006 it was a "stealth premiere" of the finale of ''PerfectHairForever''; in 2007 they aired the complete ''WesternAnimation/AquaTeenHungerForce [[TheMovie Colon Movie Film For Theaters]]'' several weeks ''before'' its actual theatrical premiere date - in a small, 1 x 1 inch corner of the screen; in 2008 it was a whole night of "stealth premieres" and in 2009 it was the cable premiere of ''Film/TheRoom''. In 2010 and 2011, they aired ''The Room'' '''again'''. In 2012, they opted for a one-day revival of {{Toonami}}, which began with a FakeOutOpening of ''The Room'', and was so well received that the block was brought back for good!
** Memorably, the fart gag caused such an angry and ''immediate'' InternetBackdraft that the sounds were removed for the late-night second airing.
** In 2013, they changed the name of the network to [meow meow], played cat-related bumps and superimposed cat heads on all their programming (except ''Loiter Squad''.)
** In 2014, they released a new episode of ''WesternAnimation/PerfectHairForever'', out of the blue, in homage to the gag from 8 years before.
** 2015's April Fools joke was simple: an ''ATHF'' marathon with a "[[https://www.youtube.com/watch?v=BBvY67L2vRE coin hunt]]".
* [[http://www.snopes.com/photos/airplane/hotelicopter.asp The Hotelicopter]].
* For 2008, the morning [=DJs=] at WBPM in upstate New York announced they were quitting. All throughout their show, they received calls from listeners asking if it was true and begging them not to do it. Just before they signed off, they admitted that they ''were'' quitting... smoking.
* In 2008, users of the [[UsefulNotes/{{Unix}} Kubuntu Linux]] beta found that their wallpapers were now one of those TastesLikeDiabetes [[http://img146.imageshack.us/i/schermata1pq5.png/ unicorn images]]. And that the dialog boxes for changing the wallpaper were disabled.
* In the late 1980s, the U.S. Armed Forces Network (radio) in Europe celebrated April 1st with such news items as an invasion of Germany by giant grasshoppers. Also, the German "phrase of the day" feature was replaced with a ''cow'' phrase: "Moooo!" which means, "Hey, watch where you're putting those cold hands, buddy!"
* Something about the radio business must really lend itself to these. From 1964, [[http://www.musicradio77.com/images/apfool4pcm.mp3 here's WABC's Dan Ingram]] being victimized during his on-air shift.
** George Weber, who hosted a talk show on KOA in Denver in the early 1990s, was fond of elaborate April Fools pranks. These included: telling listeners that the gold on the dome of the Colorado state capitol building was being replaced and that they could go to the grounds to get free chunks of the old gold, claiming that Denver had just built a subway system (he even mocked up a "subway entrance" at a local comedy club), and making it sound as though KOA had changed their format from talk to CountryMusic.
* On April 1st of 2010, the cd trading site swapacd.com included a link on their homepage promising users "free credits". Instead of credits that can be exchanged for [=CDs=], what they got were the kind of credits you see at the end of movies - a scrolling list of bad puns on names of famous actors.
* ''All Things Considered'', the evening news program of Creator/{{NPR}}, does an annual April Fools news story, delivered in their usual deadpan style. Among others was a report on the dangers of exploding maple trees in Vermont one year, and then another was a reading outraged "listener mail" concerning Whale Farming (as in, raising whales in massive tanks in the Midwest) which was a long series of ComicallyMissingThePoint gags.
* The Swedish television channel SVT had a glorious one in 1962. Known radio technician Kjell Stensson told the viewers that by simply cutting up a nylon stocking and attaching it to the television screen, they would get color TV!
* A few years ago one Christchurch newspaper published a news report about how the iconic Christchurch City Cathedral was going to be demolished due to bad structural damage. This became HarsherInHindsight considering the catherdral ''was'' demolished in 2012 after a 7.9 earthquake struck the city.
* In the 80s, the Australian {{Cricket}} team played a tour match in India on April 1st. The rules of cricket state that if the ball hits the stumps but fails to dislodge the bails, the batsman is not out. The Australians ''superglued the bails on'', and then just stood back and let the ball hit the stumps.
* For 2011, {{Channel 4}} modified their (live-action with CGI effects) {{Station Ident}}s for the day by [[https://www.youtube.com/watch?v=Wts8vOSyWdg removing the CGI 4 logos]].
* On April Fools' Day 2011, Creator/ShoutFactory announced on its website that it would be producing a DVD box set containing the entire 72-year run of the radio/TV soap opera ''Series/GuidingLight'', collected on nearly 4,000 discs.
* On April 1, 1966 the well-known BuccaneerBroadcaster Radio London, operating from a ship off the British coast, found its signal being drowned out by Radio East Anglia, which claimed to be broadcasting with an implausibly-powerful transmitter from somewhere in eastern England. This was so convincing that the police actually searched the region for illegal transmitters. Naturally they never found one, because the whole thing was broadcast from the Radio London ship with the help of two fake [=DJs=] (actually engineers) and good editing. It had all been planned by a couple of the real [=DJs=] - without the knowledge of the station's management, who weren't happy at the loss of scheduled commercial slots.
* Creator/TheCriterionCollection announced an upcoming release of ''Film/{{CHUD}}'' on their website on [[http://www.chud.com/45898/were-getting-criterioned/ April Fools Day 2011]]. Then they announced a ''Film/KindergartenCop'' release [[http://www.iwatchstuff.com/2012/04/criterion-collection-releases-kindergart.php the following year]].

[[folder:TV Tropes]]
* For April Fools 2011, all the avatars in the TVTropesForum were changed to [[http://static.tvtropes.org/pmwiki/pub/images/april_fools_2011_spartacus_8552.png a picture of]] Film/{{Spartacus}}, and [[IAmSpartacus all usernames had "Spartacus" placed in front of them]]. After that, they began to rotate between several others, including:
** [[Franchise/StarWars A Stormtrooper's helmet]], changing everyone's name to "Trooper [Troper's name]". [[http://static.tvtropes.org/pmwiki/pub/images/april_fools_2011_trooper_5853.png]]
** A {{Bear|sAreBadNews}}, with "Grizzly [Troper's name]". [[http://static.tvtropes.org/pmwiki/pub/images/april_fools__2011_bear_6305.png]]
** A [[Franchise/MyLittlePony purple, butterfly-winged pony]], with "Pony [Troper's name]". [[http://static.tvtropes.org/pmwiki/pub/images/april_fools_2011_pony_7896.png]]
** Franchise/SpiderMan, with "Spider-[Troper's name]". [[http://static.tvtropes.org/pmwiki/pub/images/april_fools_2011_spiderman_3825.png]]
** [[WesternAnimation/LooneyTunes Tweety Bird's]] head, with "Tweety [Troper's name]". [[http://static.tvtropes.org/pmwiki/pub/images/april_fools_2011_tweety_6095.png]]
** [[Series/{{Firefly}} Serenity]], with "Still Flying: [Troper's name]". [[http://static.tvtropes.org/pmwiki/pub/images/april_fools_2011_serenity_5847.png]]
** A [[NothingIsScarier blank]] [[OurGhostsAreDifferent space]], with "Ghostly [Troper's name]".
** And a [[Series/DoctorWho Weeping Angel]], with "Unblinking [Troper's name]". [[http://static.tvtropes.org/pmwiki/pub/images/april_fools_2011_unblinking_3564.png]]
** April Fools' Day 2012 started a little bit early ("Somewhere on Earth it is April 1st") on this wiki, with the home page being translated to a random language, including Portuguese, Redneck, and [[Franchise/StarWars Yoda]].
* For the MohsScaleOfRockAndMetalHardness, some joker entered [[http://www.youtube.com/watch?v=JN5Mqr6tRlw Hugga Wugga]] from TheMuppetShow under Level 7 ("Soprano and gravel"), and Cookie Monster's [[http://www.youtube.com/watch?v=Ye8mB6VsUHw C Is For Cookie (That's Good Enough For Me)]] under Level 9 ("Cookie Monster vocals - the TropeNamer"). Someone fell for it.
* April Fools' Day 2012 had a couple unrelated events:
** [[Administrivia/KnowTheStaff The moderators]] had a lot of fun within the forum. Most of them wear distinctive avatars, sig lines, and other gingerbread, and these have become well known enough that people identify the mods by their avatars rather than their names (to the point where @/FoxxyMod redirects to @/{{Madrugada}}, since she always has [[http://static.tvtropes.org/pmwiki/pub/images/Vulpes_vulpes_laying_in_snow.jpg_100.jpeg an avatar of a sleeping fox]]).\\
For April Fools' Day, they "dressed up" as each other: Each wore the gingerbread of someone else. This led to much confusion and silliness, since people suddenly thought the mods were posting in places they had never been before, e.g. @/BestOf took on @/FastEddie's avatar, signature, user title, and location, so people thought Fast Eddie was posting in Yack Fest, which rarely happens. [[http://tvtropes.org/pmwiki/posts.php?discussion=13331907300A61220100 Here]] is the main forum thread about it, including [[http://static.tvtropes.org/pmwiki/pub/images/April_Fools_2012_mod_switches_4386.png diagrams of who switched to who]].
** It expanded outside the forum too.

Because of the obscure home pages getting a lot of exposure, we ended up with [[JustForFun/WeirdestInboundLinkOfTheDay some weird inbound link counts]] as people showed them to their friends.
* 2013 brought the scale down again -- nothing happened wiki-side. On the forums, the mods once again had their avatars changed, this time to Agent Smith from ''Film/TheMatrix'', but that was all. The main event was that location lines in posts were randomised. Instead of the location given in your profile, your location would be randomly selected from one of 256 possibilities the mods had previously compiled, and would rerandomise upon refreshing the page. Most locations were references to works. For example, you might be listed as "from"...

* ''DemashitaPowerpuffGirlsZ'': The announcement that there was going to be a MagicalGirl anime SpinOff of ''ThePowerpuffGirls'' was presumed as an April Fools joke due to being announced on said date.
** More than that: it was announced on an April 1st, then nothing was said about it for months and months, with no new information to be had anywhere, until a follow-up announcement on, you guessed it, the following April 1st.

[[folder:Comic Books]]
* A few years ago, Marvel announced that ''ComicBook/SpiderGirl'' had been UnCancelled on April 1st.
* ''ComicBook/MyLittlePonyFiendshipIsMagic'' #1 was released on April 1st, 2015.

* The [[http://insidemovies.ew.com/2011/03/31/leonard-nimoy-transformers-dark-of-the-moon/ casting]] of Creator/LeonardNimoy as the voice of Sentinel Prime in ''Film/TransformersDarkOfTheMoon'' was announced near April 1st. Extra skepticism points thanks to Nimoy's retirement from acting (which clearly didn't stick as he's continued to act until his passing in 2015).
* The trailer for ''WesternAnimation/TheSimpsonsMovie'' was released on March 31, 2006 with the second ''WesternAnimation/IceAge''. Despite being one day before April 1st, it did create some initial beliefs that Fox had been pulling an early April Fools' Day joke.
* The announcement that Creator/HideakiAnno [[http://www.animenewsnetwork.com/news/2015-03-31/evangelion-hideaki-anno-is-new-japanese-godzilla-film-chief-director-writer/.86598 would be directing]] a ''Franchise/{{Godzilla}}'' film. It was announced on March 31st, but due to timezones it was April 1st in Japan.

* Kasane Teto, vip@2Ch April Fools joke {{Music/Vocaloid}}, actually did have her own voice, albeit synthesised in different program. And free.
** Inhabitants of vip@2ch used to do it every year since then.

[[folder:New Media]]
* Website/{{Google}}'s Gmail service was announced on April 1, 2004 with storage limits that (at the time) sounded absurdly unfeasible; it was no joke. Since then, Gmail has run an April Fools' joke every year, including such "new features" as a free email printing service (subsidized by giant red context-sensitive ads on the back of the emails) and a feature allowing the user to send an email to days earlier.
** The [[http://googlepress.blogspot.com/2004/04/google-gets-message-launches-gmail.html press release]] was even intentionally written to look like an April Fool's joke, tricking everyone who thought they weren't falling for the trick.
** And in 2007, a Google NY employee had to continuously state that his [[http://googleblog.blogspot.com/2007/04/snakes-in-plain-old-office-building.html 3 foot python really was loose in the building]].
* Popular gaming site The GIA[[labelnote:initialism]]'''G'''aming '''I'''ntelligence '''A'''gency[[/labelnote]] suddenly announced its dissolution on April 1, 2002. Readers were confused for ''months'' before finding out that, yes, it really was closing down, and many were angry that they would pick April 1 of all days to make the announcement. The GIA was later retooled into the ill-fated [=GameForms.com=], which didn't last very long and has now been replaced by a poker site.
* ''WebVideo/NarutoTheAbridgedComedySpoofSeriesShow'' was meant to be one of these, but it ended up as a side project of [=LittleKuriboh=]'s. It currently has 5 episodes.
** That was 2009's AprilFools joke. In 2008, he made a fake ending to the series and "moved on" to Zork and Pals. Then in 2010, he created "a Anime/YuGiOh5Ds abridged" with everyone just shouting "CARD GAMES ON MOTORCYCLES!!!"; then it turned out to be Iruka and Joekage watching it and then showing each other their abridged series. Naruto lampshades at the end how tired it's gotten and complains.
* An ''accidental'' subversion: [[http://www.gamefront.com/ Gamefront]] (known back at the time of the incident as Filefront) announced on March 24, 2009, that they planned to shut down by the end of March. However, they managed to deal with their issues at that very moment and thus didn't close down after all; they just happened to be unfortunate enough to solve their problems by April 1st.
* Like ''Naruto The Abridged Comedy Spoof Series Show'', ''MyLittlePonyCamaraderieIsSupernatural'' started as an April Fools' joke for 2011 from the creators of ''WebVideo/SonicF''. It got popular enough that another episode was made.
* WebVideo/ReZonanceSoundtrackReviews' Bubble Bobble's soundtrack review ran on April 1, 2013. After a lampshade of the trope, the review was played completely straight. [[NotMakingThisUpDisclaimer It wasn't a gag review, or a prank, it was a straight up honest review.]] It even plays an important part to the continuity of the reviews.
* On April 1, 2010, [[Webcomic/{{Sonichu}} Christian Weston Chandler]] vandalized the [[http://sonichu.com/cwcki/List_of_Christian%27s_edits_to_the_CWCki CWCki]], a site dedicated to him and his webcomic. Most users assumed it was a prank at first.

[[folder:Tabletop Games]]
* The official ''MagicTheGathering'' website pulls off some sort of elaborate joke every year on April 1st, but occasionally hides some truth in it as well. Perhaps the best trick they pulled was on April 1st, 2004, when they announced ''Unhinged'', a sequel to the popular ''Magic'' joke set ''Unglued''. A few days later, it was revealed that the announcement was '''true'''.
** Aaah, but when else to unveil new Unglued cards but that most auspicious of days?
** The ''real'' Fool's Day Joke was the announcement that they were banning the Plains card: one of the resource cards you need to ''play the game''.
** In 2010, they put up an "Arcana" (mini-article) that was just a LongList of [[SuspiciouslySpecificDenial increasingly ludicrous]] rumors they want to debunk. Only the first 5 or so (of 38) were plausible enough to merit debunking.
* Sanguine Productions' 6-page, $1,279.95 PDF supplement for ''TabletopGame/{{Ironclaw}}'', known as The Book of Fools, is free on April Fool's Day.

[[folder:Theme Parks]]
* 2014 finally saw the debut of WesternAnimation/OswaldTheLuckyRabbit as a mascot in the Ride/DisneyThemeParks, specifically in Tokyo Disney Resort. Of course, [[http://disneyparks.disney.go.com/blog/2014/04/oswald-the-lucky-rabbit-makes-his-debut-at-tokyo-disneysea/ since the announcement happened on April 1]], one of the first comments was a verification on whether or not this was an April Fools' prank.

[[folder:Video Games]]
* Announced on April 1st 2012, ''VideoGame/SaintsRowTheThird: Enter the Dominatrix'' was thought to be an April Fools Joke until it was later revealed to be a real standalone companion game retailing for $30. Triply subverted as development on the game got so ambitious that it got revamped into ''VideoGame/SaintsRowIV'', and ''then'' the first ''Saints Row IV'' mission DLC is called — wait for it — ''Enter the Dominatrix''.
* ''[[VideoGame/DefJamSeries Def Jam Vendetta]]'' had an initial release date of April 1, 2003. Hardly anybody took seriously the idea of a LicensedGame where rappers beat the stuffing out of one another. The game actually met the April 1 release date, and it sold like hotcakes, inspiring a pair of sequels.
* As with several earlier examples, [[SquareEnix the merger of Squaresoft and Enix]] was initially thought to be an April Fools' Day prank because it was announced on April 1.
* ''VideoGame/TeamFortress2''[='=]s Jarate weapon for April Fools' Day 2009 is now a genuine weapon as of the Sniper vs. Spy update, release by the end of May 2009.
** Valve have also made multiple ''VideoGame/{{Counter-Strike}}'' April Fools' Day updates.
** On the subject of Valve again, 13 indie games on UsefulNotes/{{Steam}} saw odd updates relating to potatoes on April 1st, 2011. Surely enough, these potatoes served as the omen to [[http://valvearg.com/wiki/Valve_ARG_Wiki something]] [[VideoGame/{{Portal}} more]] [[AlternateRealityGame sinister]] than a mere foolish prank...
** The 2013 April Fools was a form of zig-zag, since it was originally a straight-up joke (see Reddit's section in New Media above), but resulted in two new promotional hats for Reddit being added into the game two days later.
* Similiar to the ''Powerpuff Girls Z'' example above is ''VideoGame/MarioAndSonicAtTheOlympicGames'', which was also announced near April 1st and thought to be an elaborate prank.
* Similar to the previous example is ''VideoGame/PokerNight2''--however, the ''VideoGame/TeamFortress2'' items that you can get from this game were added to the ''Team Fortress 2'' files before it was even teased.
* Version 0.31.01 of ''VideoGame/DwarfFortress'', two years in the making, was released on April 1, 2010. No surprise that the website broke within the hour.
* Ogmo from ''VideoGame/{{Jumper}}'' has been announced to be a playable character in ''Super VideoGame/MeatBoy''. The fact that Ogmo and Meat Boy himself are look-alikes left those who saw the news skeptical.
* ''{{Narcissu}} -side 2nd-'' was supposed to be released on April Fools' Day. It got updated a few hours early, and some still think it's an April Fools' Day joke.
* One April Fools Day, Max Barry announced that the UN-like organization in his browser-based nation simulation game {{Nationstates}} would change its name to the World Assembly because of a complaint from the real UN about his use of the name and emblem. Turns out, the UN really did send him a letter, and the change was made to comply with it.
* ''VisualNovel/HatofulBoyfriend'''s introduction states that the character designs were released on April Fools' Day, and there's an anecdote (could be truth, could be just an UrbanLegend) that the creators of this game had originally intended for the game to be a normal DatingSim with human guys and posted bird designs for these guys on the website as an April Fools' joke, only for fans to love them so much that the game ended up being all about dating birds instead.
* Rovio Mobile announced an ''VideoGame/AngryBirds'' [[TheAnimeOfTheGame animated series]] on April 1st 2012.
* Whilst ''VideoGame/LeagueOfLegends'' usually plays this straight, a notable subversion was the announcement of the long awaited champion Lee Sin, the Blind Monk who was released a few days later. In the April Fool's version, he was indestructible and could kick across the map but the player was filtered through a blurry screen. Here's the [[http://www.youtube.com/watch?v=i3DWCGs3Tl8 April Fools spotlight]] compared to the [[http://www.youtube.com/watch?v=e6SleHuJjLo real spotlight.]]
* The remake of ''VideoGame/LaMulana'' had an AprilFools trailer, but not everything shown in it is fake...
* The announcement of ''VisualNovel/{{Rewrite}}'' by Creator/KeyVisualArts on April 1st 2008 was subsequently validated the following day.
** The announcement that Rewrite would be an adult game on April 1st 2010 was revealed as a joke.
** The release of a video showing the characters in distinctly un-Key like situation on April 1st 2011 was also confirmed the following day (and the events in video do actually happen in the novel).
* For VideoGame/WarThunder, in 2013 Gaijin Entertainment released a trailer showing [[WesternAnimation/MyLittlePonyFriendshipIsMagic cute, colorful ponies]] as a new playable faction. Then they actually updated they game to include said ponies, each packing 4 20mm machine guns, 8 rockets tubes, and 2 half-ton bombs. Oh, and they each flew like a high-speed rocket plane. [[PeripheryDemographic Bronies]] were ecstatic, while brony-haters were... uh... [[StopHavingFunGuys not]].
** In 2014, they added a Kaiju snail for the japanese army. With eye stalk lasers.
* In 2013, Konami [[http://i.imgur.com/4YXAMGH.png redecorated]] the ''{{jubeat}}'' e-Amusement website to promote "Wow Wow VENUS", with the unlock condition for the song ostensibly requiring tons of LevelGrinding. The site was reverted the day after as expected...but then, much to the joy of players wanting to play it, "Wow Wow VENUS" became an ''actual playable song'' the day after, freely available with no unlock precondition for one week, permanently so for the player if they played it once during that week. Currently, the song can be obtained by grinding through the "bistro saucer" unlock system.
* In 2014, ''{{VideoGame/Skullgirls}}'' developers [[https://www.youtube.com/watch?v=IXN5yr4dGIc revealed]] the newest addition to the game's cast: PaletteSwap MovesetClone character Fukua. Intended as a quick TakeThat against a [[https://www.youtube.com/watch?feature=player_embedded&v=dC-Hl33Xqpk certain other character trailer]], she was removed from the game shortly after AprilFools... and was later permanently added, with a complete moveset and her own story mode.
* ''VideoGame/TheBindingOfIsaac'' was confirmed for the 3DS, {{Wii U}}, and XboxOne on [[http://bindingofisaac.com/post/115192982234/rebirth-coming-to-3ds-wiiu-and-xbox1 April 1, 2015]]. Due to the timing, and a well known history that [=BoI=] has previously run into issues being released on Nintendo's eShop service, some thought it really was a joke, prompting the game's creator [[https://twitter.com/EdmundMcMillenn/status/583164512330592256 to state on Twitter that it's no joke]]. The dev did take the chance to still add in some jokes though, by making a (now crossed out) joke post stating that the Nintendo versions would also replace "blood" with "sweat" (a la the SNES version of MortalKombat) and "pills" with "lollipops," and claiming that the references to Christianity would be replaced by references to Scientology (when in reality the game will be uncut on all platforms, including Nintendo's).
* {{Nintendo}} made the announcement that they would indeed be holding a NintendoDirect on April 1, 2015, even stating in the announcement "despite the date, this Direct is no joke!" During said Direct they made announcements that caught many off guard, such as releasing the first debut trailer for ''Shin Megami Tensei X Fire Emblem'' (after two long years of not announcing anything besides a short teaser), announcing that the fifth entry in the ''VideoGame/FatalFrame'' series (for the Wii U) will indeed see a release outside of Japan (after the previous entry failed to see an official non-Japanese release), [[{{Mother3}} Lucas]] will be the next DLC character for ''SuperSmashBros 4'', [[ArsonMurderAndJaywalking and even the announcement]] that ''VideoGame/DonkeyKong64'' will hit the Virtual Console service after many fans previously thought the game wouldn't due to rights issues.
* ''VideoGame/TheTalosPrinciple'' announced DLC that would replace the voice of Elohim with the voice of VideoGame/SeriousSam on April 1, 2015. It not only is an actual DLC, but it was also free for a short while.
* On April 1, 2015, Creator/BioWare revealed ZITHER!, a WanderingMinstrel mage with ThePowerOfRock as the first multiplayer DLC character for ''VideoGame/DragonAgeInquisition''. A month later, the Dragonslayer DLC was announced, and ZITHER! with his [[MechanicallyUnusualClass unique mechanics]] were confirmed as the DLC's new Mage agent.

* Subverted in 2010 by ''LookingForGroup'' who chose April 1 for some real yet unlikely plot development. It would seem that two party members met long ago, but the sane one was too badly hurt to remember in detail.
* ''Webcomic/{{Loserz}}'' brought us [[http://the-qlc.com/loserz/go/206 this strip]]. Jodie completely naked!
* After [[WebcomicTime several months]] of ''Webcomic/MegaTokyo'' being almost entirely Miho and Piro talking, April 1st 2012 unexpectedly delivered a barely offscreen naked MagicalGirl wrestling match and Piro getting smacked in the face with a washbasin. [[http://megatokyo.com/strip/1332 Canonically.]]
* On April 1, 2003, ''QueenOfWands'' put up a comic where Shannon is shown crying and announces she's pregnant; it was removed a few hours later. Naturally it caused quite a bit of discussion as some fans had seen it and some did not. One year later the comic was put up again and ''stayed'' up, beginning a legitimate story-line.
* Most of the plot of ''Webcomic/{{Exiern}}'s'' Wild North story arc was [[spoiler: brought to a sudden conclusion on April 1st 2014 when a newly arrived character [[http://www.exiern.com/2014/04/01/red-2/ interrupted the villain]]. This was so abrupt, and done by someone known to be trusted not to overreact, that]] it sparked debates as to whether it was real.

[[folder:Web Original]]
* TheOtherWiki features a set of articles each April Fools' Day, and despite their absurdity, each of them are true. The site also runs rampant with pranking, such as changing all the links on the {{Rickroll}} article to point to, well, a Rickroll.
* On the Creator/AgathaChristie section of the [[http://jdcarr.com/forum/index.php Golden Age Mysteries Forum]], one member posted a [[http://jdcarr.com/forum/showthread.php?t=3023 thread]] speculating about [[NobodyOver50IsGay a possible lesbian couple]] in one novel. Because this thread was posted on April 1 2006, another member at first thought it was a joke.
* Once there was a major ''Website/DragonCave'' release on April Fools; neither the date or the name ("Mod Madness") lent credence to the idea that no, this was a legitimate release, and the eggs weren't going to disappear or become something ridiculous.

[[folder:Western Animation]]
* The long-awaited DVD sets for both ''TinyToonAdventures'' and ''{{Freakazoid}}'' were announced by Warner Brothers on April 1st, 2008.
* On 1 April 2012, Netflix added the first season of ''MyLittlePonyFriendshipIsMagic'' to their online service. When EquestriaDaily posted about it (in the midst of a "Hasbro Takeover" for the day), no one took it seriously. The next day, people realize they weren't joking. One more day later, and ''Friendship Is Magic'' occupies the "Most Watched Right Now" spot on Netflix.
** Meghan [=McCarthy=] announced that Mike Vogel would be working on the sixth season on the 1st of April, 2015 (this was just before the fifth season even started). Equestria Daily even waited until the following day to announce this, as they knew that if they announced it then, people would think this was another joke.

[[folder:Real Life]]
* MarvinGaye was shot and killed on April 1, 1984 by his father. People were shocked the next day because then they knew it was true.
* People did not initially believe Tazz's departure from Wrestling/{{WWE}} was real because it was so close to April 1.
* You have to see this to believe it: [[http://uniwatchblog.com Uni Watch Blog]], a website dealing with sports uniforms, posted a prank article on April 1, 2009, claiming that a certain NFL team was going to adopt a lime green alternate jersey; the prank fooled the makers of [[VideoGame/MaddenNFL Madden NFL 2010]], who inserted the uniform into the game. Cue the September 28, 2009 game between the Seattle Seahawks and the Chicago Bears, and the Seahawks [[CrowningMomentOfFunny wore lime green uniforms]].
* "Think Geek" added a [[Franchise/StarWars Tauntaun]] sleeping bag to their catalog as an April Fool joke ... but response was so great they're now checking with Lucasfilms about making that bag for real. ([[http://www.thinkgeek.com/geektoys/plush/bb2e/ They got permission.]])
** The same happened with the [[http://www.thinkgeek.com/tshirts-apparel/interactive/a5bf/ Personal Soundtrack t-shirt]], which was an April Fools' Day joke that was so popular they ended up actually making one.
** Same with their ever popular [[http://www.thinkgeek.com/tshirts-apparel/hats-ties/9352/ 8-bit tie.]]
* Following a shift in power at Creator/{{CBS}} Sports and complaints over his being overexposed on the network (and appearing to be overly power-hungry), sportscaster [[CaptainObvious Brent Musburger]] ended up getting fired on April 1, 1990, with the NCAA Basketball Championship game serving as his lame duck assignment prior to joining Creator/{{ABC}} Sports.
* The death of comedian Creator/MitchHedberg was questioned because it was announced on his website on April Fool's Day.
* Creator/SteveJacksonGames had an announcement about the long-desired ''Ogre'' update on April Fools Day 2012. But it wasn't a joke, the wargame ''is'' being republished. (The Kickstarter campaign was fully funded ''before the formal announcement''.)
* The April Fools equivalent in Hispanic countries is December 28. Be wary of the media in those parts of the world those days.
* [[http://en.wikipedia.org/wiki/April_Fool%27s_Day_Blizzard The April Fool's Day Blizzard]]. After a fairly below average winter, some people didn't believe that a huge blizzard would hit a week and a half into Spring; it ended up being Boston's third (now fourth) biggest snowstorm ever, coming only an inch shy of the winter season's 26 inches.
* Traditionally in the UK, if you try to pull an April Fool joke after mid-day, you ''are'' the fool, as April Fool's Day ends at mid-day. If someone tries to pull an April fool's prank on you after this point, you can get them back by chanting a rhyme similar to the following[[note]]there are several variations[[/note]]:
--> April Fool's Day is past,
--> You're the biggest fool at last!
* [[Music/TheBeatles Cynthia Lennon]] died of cancer on 1 April 2015.
* Also in 2015, Amazon announced their dash button service on March 31. They actually had to flat-out explain that [[http://www.usatoday.com/story/tech/2015/03/31/amazon-dash-ordering-button/70747342/ it wasn't an April Fools joke.]]
* The AMC Gremlin - the first American car designed to compete with foreign compacts - debuted on April 1, 1970. The car's highly divisive appearance ("Where's the other half of your car?") led many to call it a joke.
