Yes, Comedy is supposed to be funny by its nature, but sometimes, in hindsight it becomes even funnier.

* The 1996 movie [[http://www.imdb.com/title/tt0117102/ Mr. Wrong]], now that Ellen is an out and proud lesbian.
* [[http://www.theonion.com/content/node/33930 This article]] in ''TheOnion'' predates the popularity of five-blade razors by some time.
** And earlier, ''Series/SaturdayNightLive'' had a gag ad about three-blade razors. "Because you'll buy anything." Now, if only three-blade razors actually fit in Trac II handles...
*** And a ''Weinerville'' skit was for a six-blade razor. Impossible, you might ask? I give you the Gillette Fusion, a five-blade razor with an added "precision trimmer" blade on the back of the head.
** [[http://www.theonion.com/content/video/9_11_conspiracy_theories One skit]] on ''Website/TheOnion News Network'' had a representative of Al-Qaeda get into a furious argument with a 9-11 conspiracy theorist who claimed Al-Qaeda did not plan and execute the 9-11 attacks. The Al-Qaeda represenative assured the conspiracy theorist that Al-Qaeda was, in fact, responsible. Later, the ''real'' Al-Qaeda representative, al-Zawahiri, released a statement attacking 9-11 conspiracy theorists and claiming 9-11 conspiracy theories were all a plot by Shiites to discredit Sunni terrorists, as shown in [[http://www.usatoday.com/news/world/2008-04-22-2120396933_x.htm this article]].
** Even before that, Popular Science in 1933 predicted [[http://blog.modernmechanix.com/five-bladed-razor-cuts-shaving-time/ this]]

** [[http://www.thedailyshow.com/video/index.jhtml?videoId=216562&title=liam-neeson This Daily Show interview with Liam Neeson]], and the strange course it quickly takes, converted this [[http://www.theonion.com/content/video/man_who_crossed_nation_in_balloon recent Onion skit]] from pointed satire to simple parody. Conspiracy may be at work.
** One Onion article, [[http://www.theonion.com/articles/progressive-parents-refuse-to-tell-child-its-sex,18395/ Progressive Parents Refuse To Tell Child Its Sex]], got a lot funnier when a couple [[http://abcnews.go.com/Health/genderless-baby-controversy-mom-defends-choice-reveal-sex/story?id=13718047 who kept their child's gender under wraps]] made headlines.
** In the Sports section, there's "Brady Quinn: 'I'm Going to Be a Bust'"; which is funny for three reasons:
*** Brady Quinn ''has'' been a bust so far, largely sitting on the bench for much of his career.
*** One of the players he suggests people look at in his place is [=JaMarcus=] Russell, who would go on to make a solid case for "biggest draft bust of all time".
*** The article mentions that Al Davis was more interested than ever in drafting him. Davis would draft the aforementioned Russell.
** There was once an article about then-president George W. Bush appointing someone to run the country, run well before the crux of the 2008 presidential election. Towards the end of the article, it was mentioned that the top two choices were Barack Obama and John [=McCain=] - the two men who would ultimately duel for the presidency.
** [[http://www.theonion.com/articles/bush-our-long-national-nightmare-of-peace-and-pros,464/ Bush: Our Long National Nightmare of Peace and Prosperity is Over]] was written immediately prior to Bush taking office, noting that Bush was going to start at least one Gulf War level conflict, cut taxes leading to a drop in spending and a worsening of the economy, followed by a tax hike which would make the economy even worse, fighting against environmental regulation and abortion rights, and trying to prevent black people from voting. This has become increasingly funny over time (or depressing, depending on your point of view).
** The article [[http://www.theonion.com/articles/jack-harbaugh-admits-hes-pulling-for-tom-brady-to,30960/ Jack Harbaugh Admits He's Pulling for Tom Brady to Win]] was already funny when it ran because two of Jack's sons[[note]]John, coaching the Baltimore Ravens, and Jim, coaching the San Francisco 49ers[[/note]] were coaching in the playoffs. It was made funnier when both of their respective teams won their conference championships, meaning they'd face each other in the Super Bowl.
* Traditionally, ''Series/TheDailyShow'' (and before that Comedy Central in general) calls its coverage of the presidential elections "Indecision (Year)"... as the recounts dragged in the Bush/Gore race, ''Indecision 2000'' just kept getting funnier and funnier.
** Lampshaded by host Jon Stewart on November 8th - "Calling this whole thing Indecision 2000 was at first a bit of a light-hearted jab, perhaps an attempt at humour - we had no idea that people were gonna run with that. We thought we were kidding, quite frankly."
* For his column the day after the 2000 election, humorist DaveBarry did an election result analysis, which had lots of blanks and instructions to the editor to fill them in with the winner. The joke was supposed to be that he just watched ''Series/BuffyTheVampireSlayer'' instead of election coverage and didn't bother to find out who actually won. The way it actually turned out made it a lot funnier.
** Dave Barry lampshaded this himself when he included that column in a book he later did.
--> What follows is a series of columns I wrote for the ''Harold'' about that election. The first one, which appeared the day after Election Day, was an "analysis" of the election results. The joke was supposed to be that I wrote this analysis without knowing who the winner was. Little did I realize that this would still be a mystery ''weeks'' after the column appeared.
* In a game of "Newsflash" on ''Series/WhoseLineIsItAnyway'', Colin started it off by saying "It all started with a badly timed bald joke." [[http://www.youtube.com/watch?v=-yQDCLGMv7c The rest really needs to be seen.]] Also LateToThePunchline: the moment came quite some time later when they were back in their seats, with Colin muttering, in part sportsmanship, part horror, "I said the bald joke thing too."
* [[http://www.youtube.com/watch?v=NXhv7q6R8dw This Letterman sketch]] seems much funnier to fans of ''Series/{{Torchwood}}''...
* ''[[http://planethalflife.gamespy.com/ Planet Half-Life]]'' once did an April Fools' joke announcing ''VideoGame/HalfLife2''...
* Similarly, ''[[http://www.kryptonsite.com/ Kryptonsite's]]'' annual April Fool's news articles regularly foretell actual developments on ''{{Smallville}}''. The introduction of Mr. Mxyzptlk, Pete Ross leaving, and the Lex/Lana relationship were joked about in 2004, Dean Cain appearing on the show was foretold in 2005, 2006 spoke of an episode called (and including) Bizarro, while 2007 suggested an episode called 'Kara' might introduce {{Supergirl}} to the show, while 2008's April Fools mentioned an episode called '[[ComicBook/{{Legion of Super-Heroes}} Legion]]'. In some way or another, every one of those has come true...
* Another example of a strange convergence between real news stories and TheOnion is discussed [[http://www.sciam.com/article.cfm?id=kha-nyou-smell-a-rat here]].
* There was a sketch in ''Series/InLivingColor'' with ''Film/HomeAlone'' and Michael Jackson that was made in 1992, before any of the sequels were made (''Lost In New York'' and the made-for-TV and made-for-home-video ones made without Macaulay Culkin), and before Jackson's child molestation accusations came out. The dialog makes it even funnier.
** And there's also the exchange "I've got naked pictures of my sister." "Who doesn't?" At the time, it was a reference to La Toya Jackson's ''Magazine/{{Playboy}}'' appearance, but after Janet Jackson's WardrobeMalfunction at the 2004 Superbowl (and the ensuing ExecutiveMeddling over obscene content on TV), the joke now has some new life to it rather than being an UnintentionalPeriodPiece.
* ''NevermindTheBuzzcocks'': When Mark Lamarr introduced guest Simon Amstell, he listed his achievements and joked "He's stealing my act!". Exactly three years later, guess who took over hosting the show...
* Tim Clague uploaded the short video ''[[http://www.richarddawkins.net/article,3506,God-Versus-The-Advertising-Standards-Authority,Tim-Clague God Versus The Advertising Standards Authority]]'' about a priest being told to edit his "misleading" Christmas advert. Two weeks later, Stephen Green of Christian Voice [[http://www.politics.co.uk/news//opinion-former-index/legal-and-constitutional/christian-challenges-atheist-bus-advert-$1259459.htm complained to the ASA]] about an atheist advert on buses, apparently not realising what impact any such ruling would have on Christian adverts.
* In 1994, ''Saturday Night Live'' puts on a sketch involving [[http://www.hulu.com/watch/4139/saturday-night-live-steve-martins-penis-beauty-creme "Steve Martin's Penis Beauty Cream"]], featuring the line, "Just take a small amount and rub gently on the penis for several minutes up to a half-hour. You'll notice a difference right away!" Everyone laughs. About a decade later, [[http://www.youtube.com/watch?v=Ze3a1kaSAo8 Maxoderm]] hits the market, ''with the exact same advertising pitch''.
** ''Saturday Night Live also accidentally predicted SpikeTV in a sketch where fake commercials for "The Man Channel" showed nothing but cars crashing, driving off cliffs, and generally [[EveryCarIsAPinto exploding]] at the slightest provocation in SloMo.
** Then there's this sketch on the season 30 episode hosted by Tom Brady, where Seth Meyers plays Peyton Manning, who asks Tom Brady why Brady was chosen to host over Manning. The real Peyton Manning would host two seasons later.
** The last sketch of the season 34 premiere episode hosted by Olympic swimmer Michael Phelps had a fake commercial for Michael Phelps' infamous 12,000-calorie diet that only works for him (and a cameo by Subway spokesman, Jared Fogle, who declares that the Michael Phelps' Diet "sucks a foot long"). Fast forward to the Bradley Cooper[=/=]TVOnTheRadio episode on February 7, 2009, where Seth Meyers does a Weekend Update joke about Michael Phelps getting busted for smoking marijuana from a bong, with the punchline, "Though, suddenly, the Michael Phelps Diet makes a lot more sense," with a photo of Michael Phelps surrounded by two stacks of pancakes (which were featured in the "Michael Phelps Diet" commercial). Fast forward further to June/July, where Subway actually had a commercial with Jared Fogle and Michael Phelps, together again. It's like a real-life Chekov's Gag.
** "It's funny that pirates were always going around searching for treasure, and they never realized that the real treasure was the [[BlackComedyRape fond memories]] they were creating." So said Jack Handey in one of his Deep Thoughts segments. You'd be forgiven for thinking that the quote had anything to do with that ''Manga/OnePiece'' manga/anime that was released later that decade.
** Lily Tomlin hosted an early episode where the recurring puppet character Scred developed a crush on her. She awkwardly responded that being in a relationship with a puppet wouldn't be the best career move for her. One wonders nowadays if she would have responded better to a female puppet.
** A sketch in 1995 had Ellen [=DeGeneres=] (played by KidsInTheHall regular Mark [=McKinney=], who was also on SNL) & Anne Heche (Chris Kattan) on Oprah Winfrey's (Tim Meadows) show talking about their relationship, with the sketch implying that Heche wasn't really a lesbian and had only become one to get fame. Seeing as what happened several years later, SNL was on the ball with this one.
** [[http://www.hulu.com/watch/11203/saturday-night-live-digital-short-the-mirror The Mirror]] Digital Short. Now, when did I last see [[{{Inception}} Ellen Page trapped in a dream]]?
** A season 36 episode featured a fake trailer for the movie ''Unstoppable''. Denzel Washington (played by Jay Pharoah) asks Chris Pine (played by [[Series/MADtv Taran Killam]]), "Where'd you learn trains, huh? ''ThomasTheTankEngine''?" Couple months later, Cartoon Network's sketch show ''WesternAnimation/{{MAD}}'' came up with their parody of ''Unstoppable'' that also had a reference to ''Thomas The Tank Engine'' (only ''MAD'''s version combined ''Unstoppable'' with ''Thomas The Tank Engine'').
** On the season 24 Christmas episode hosted by Alec Baldwin, JimmyFallon takes Baldwin on a trip to the future which depicts what ''SNL'' will be like in the year 2011 (Fallon says the episode they're visiting is from December 12, 2011, which was a Monday this year). Despite this mistake and others that stem from the fact that the show has changed its image since the 1990s (the wrought-iron alley way stage was changed to one modeled after Grand Central Station, the majority of cast members they have now are younger than the show itself [starting with Kenan Thompson], John Goodman hasn't been seen on the show since his cameo on the last episode of season 28 hosted by Creator/DanAykroyd, R.E.M. would break up in 2011 and hence, not be musical guests, and Don Pardo is still announcing and hasn't been replaced by a robot), the whole "Jimmy Fallon will host a future Christmas episode" deal did come true.
** During the [=LeBron=] James episode, Jason Sudeikis' surly boom mike character Jeff challenges [=LeBron=] to a game of basketball after saying, "We shoulda got Dwayne Wade anyway. At least he's got a ring." A few years later, James and Wade would become teammates.
** On the season 36 episode hosted by Paul Rudd, there is a sketch where Julian Assange (played by Bill Hader) sends a video threat to the world from prison. One of his lines was, "This Monday, I was arrested, proving that, '''for those who terrorize the United States, there's nowhere to hide. America will find you, and they will punish you -- unless, of course, your name is Osama bin Laden'''." The last part is bolded because, eleven episodes and around six months later, it would be proven wrong.
** During the SNL Digital Short in the Gwyneth Paltrow/Cee-Lo Green episode, Andy Samberg asks Anderson Cooper if he ever "got freaky with Barbara Walters". Cooper's response is along the lines of "Are you insane?" before getting nailed in the head by Pee Wee Herman. The joke when the episode first aired was that Andy and Pee-Wee Herman were, yes, pretty much drunk and insane at the moment, but now that Cooper has revealed that he is, in fact, gay, the joke is funnier because Samberg comes off as more of an idiot than normal.
** The fact that SethMacFarlane would become one in a long line of ''SNL'' hosts is funny, considering that all three of his cartoons (''WesternAnimation/FamilyGuy'', ''WesternAnimation/TheClevelandShow'', and ''WesternAnimation/AmericanDad'') have trashed ''SNL'' and its cast members. What's really funny is that the ''WesternAnimation/FamilyGuy'' episode "420" (the one where Brian petitions Quahog to legalize marijuana) has a scene where Peter is so stoned that, rather than set up a cutaway joke, just shows a list of celebrities he hates. The two people on that list are JustinTimberlake (who isn't a cast member, but has hosted and cameoed enough times to at least qualify as an honorary cast member) and Andy Samberg (who actually left the show before the season 38 premiere, which is the episode that SethMacFarlane hosted, and is now on the FOX sitcom ''{{Brooklyn Nine-Nine}}'').
* EddieIzzard: "Everyone knows marijuana's a drug enhancement that can help you on track and field to come last in a team of "eight million other runners who are all dead." Or to win five gold medals.
** His insistence that ''hopscotch'' is spooky WomensMysteries that allows them to escape TheGrimReaper becomes even more funny after seeing ''WesternAnimation/CorpseBride'', where "hopscotch" is the return word used in a specific casting of a visit-the-world-of-the-living-until-saying-the-return-word spell.
* Magazine/{{MAD}} had a ''Franchise/StarTrek'' special issue around the time of the release of ''Film/StarTrekGenerations'' which included an introductory poem reviewing the history of the franchise up to that point: the final paragraph was devoted to wondering where the series would go from there. In particular, it wondered, "Would Worf and Sulu join up with the crew of ''[[Series/StarTrekDeepSpaceNine Deep Space Nine]]''?" Well, they got it half right...Sulu did appear on ''Series/StarTrekVoyager''...
** Even more hilariously, when the ''Deep Space Nine'' crew timetravels into a classic ''Series/{{Star Trek|The Original Series}}'' episode, only one main crew member of the original Enterprise is not seen: Sulu, since he did not appear in the original episode.
** The ''Generations'' parody also included a line about how Data hoped that in the next sequel, he'd be equipped with genitalia. ''Film/StarTrekFirstContact'' comes along and sure enough, Data insists to the Borg Queen that he is "fully functional"...
*** Except the second episode of the series revealed he was "fully functional" already. BEFORE the parody.
*** And a TNG episode after Tasha Yar died revealed that he had been carrying on a relationship with her ever since a previous episode where the crew's behavior was being affected, and Tasha seduced Data. There again, he stated he was fully functional.
** In Issue #235 (Dec. '82), in MAD's satire of RockyIII (called "Rockhead III"), "Rockhead Bulboa" finds himself standing nose-to-chest when he faces off against the wrestling champion. When he is again standing nose-to-chest with "Blubber Lang," he says, "If this kind of posing keeps up, I want my next match to be with Dolly Parton!" Subsequently, Sylvester Stallone starred in the movie ''Rhinestone'', with -- you guessed it -- Dolly Parton.
* Every line Angus Deayton ever read on ''HaveIGotNewsForYou'' that made fun of someone for a drug or sex scandal. Website/YouTube commenters never miss a reference; even Ian Hislop and Paul Merton get in on it on the DVD commentary. (Paul, during a clip from the end of the first Christmas special, when a bunch of fake snow was dropped onto the set: "OH LOOK, what's all that white stuff falling on Angus?") The most infamous example: Angus asking John Simpson, after the Richard Bacon scandal, "What's your take on TV presenters doing drugs, then?"
* In 2001 Adam Buxton and Joe Cornish spoofed a show about a family living in an Edwardian era house with a sketch about ''The 1980's House'', where a modern family try to cope with being 'reduced' to living with primitive 1980s technology. In 2009 BBC Four present '[[http://www.bbc.co.uk/electricdreams/about.shtml Electric Dreams]]', about a family trying to live with 1970s, 1980s, and 1990s levels of technology: 'Will they get used to tech-free bedrooms and embrace life outside the home or will they miss their 21st Century electronic distractions?'. Or, as Adam put it: "People in the 'eighties had to take ''two'' bottles into the shower!".
* In Creator/StephenColbert's roast of the president at the the Washington Press Corps Dinner, he had a joke about what a maverick John [=McCain=] was. That was in 2006, before [=McCain=] ran for president with that as his major slogan.
* In Norm [=MacDonald=]'s last appearance on ''Late Night with Conan O'Brien'', he talked about how Leno "outfoxed" Conan (Leno was starting the 10pm weeknight show before Conan at the time). A little less than a year later, it takes on more hilarity given the fact that Conan is yet again being outfoxed.
** On the first episode of ''The Tonight Show with Conan O'Brien'', Creator/WillFerrell told Conan to enjoy the hosting the show while he could, and this was all "fleeting at best." Actually, this might be [[HarsherInHindsight Depressing in Hindsight]].
* Creator/BillHicks' [[http://www.youtube.com/watch?v=-y6j2LF6SSU whole bit]] about Billy Ray Cyrus seems even funnier [[HannahMontana these days]].
** Creator/DenisLeary was once friends with Hicks until Leary released his album ''No Cure For Cancer'', making Hicks feel Leary stole his material. Hicks died of pancreatic cancer.
** Creator/GeorgeCarlin's [[http://www.youtube.com/watch?v=Hq8pd0fDNaA already funny rant about airport security]] from ''You Are All Diseased'' came out in 1999. That is, before 9/11. After 9/11 and the recent increase in airport security to the point of public outrage, this bit will likely cause at least one death from hilarity.
** Hicks's comments regarding Music/RickAstley also apply easily to Music/JustinBieber today.
* During his "No Cure for Cancer" routine, Creator/DenisLeary joked about writing a self-help book called "''Shut the Fuck Up'', By Dr. Denis Leary". 10 or so years later, he would receive an honorary doctorate, allowing him to ''legitimately'' attach the name "Dr. Denis Leary" to a book, which was not entitled ''Shut The Fuck Up'', but rather ''Why We Suck''. Though it used the same tone as the comedy routine implied it would.
* During the Monica Lewinsky hearings, Chris Rock had a bit assailing Newt Gingrich as unattractive and accusing him of attacking Bill Clinton out of jealousy. He ended the bit by saying "Can you picture Gingrich saying 'I wish these ho's would back up off me and let a player play'." Considering the revelations that Gingrich was having an affair while persecuting Clinton and has had multiple affairs in the past, this bit fits this trope like a glove.
* ''Literature/WhyNotMe'' depicts a fictional version of the upcoming 2000 presidential election in which Creator/AlFranken becomes the Democratic nominee. He proceeds to hire an all-Jewish staff and his running mate is...Joe Lieberman. (His reasoning: he wanted to balance the ticket because "I'm Reform and he's Orthodox.") Lieberman in fact ended up being the Democratic vice-presidential candidate in 2000.
** The fact that Al Franken is now a senator brings this one step closer to reality.
* During the White House Press Correspondents' Dinner in 2011, SethMeyers made a joke that Osama bin Laden went into hiding [[TakeThat by taking up a show on political network C-SPAN]]. Within twenty-four hours, bin Laden was located and killed, and [[http://www.youtube.com/watch?v=Xun9UYCO7es the joke - along with the President's reaction to it]] - became more infamous and awesome.
* One of the songs on Music/WeirdAlYankovic's 1984 album ''In 3-D'' is a parody of Music/{{Survivor}}'s hit "Eye of the Tiger" called "Theme from ''Rocky XIII'' (The Rye or the Kaiser)." In it, Al sings about an old, broken-down Rocky Balboa running a delicatessen. He almost got it right -- in the film ''Rocky Balboa'' (sixth, not thirteenth in the franchise), Rocky is the proprietor of an Italian restaurant.
* In his 2009 comedy special ''Weapons of Self Destruction'', Creator/RobinWilliams has an entire monologue about the Roman Catholic church. First, he notes that as pope, "They don't retire the jersey like Magic Johnson, you stay in the chair till the bitter end." Pope John Paul II's successor, Pope Benedict XVI would, in fact, step down from the papacy in February 2013, becoming the first in nearly 600 years to do so. He also mentions how after Pope John Paul II died in 2005 that he hoped the next pope would be South American or Latin-American, one who would really win back people to the church. In March 2013, Pope Benedict XVI's successor, Pope Francis, became the first South American pope, and has indeed inspired people to such a degree that he got named Time Magazine's "Person of the Year" of 2013.
