!!Trivia Tropes
* ActorAllusion
** Mermaid Man and Barnacle Boy are voiced by Ernest Borgnine (at least until his death in 2012) and Tim Conway, respectively, who famously starred in [[Series/McHalesNavy a different nautical-themed comedy series]] in the '60s.
** In one episode, Mr. Krabs tells Sandy "[[Franchise/{{Highlander}} There can be only one, drylander]]!" Krabs is voiced by Creator/ClancyBrown, who played [[Film/{{Highlander}} the Kurgan]].
* AdoredByTheNetwork: One of two [[note]]the other being Cartoon Network's ''[[AdoredByTheNetwork/TeenTitansGo Teen Titans Go!]]''[[/note]] poster children for this trope. Still Nickelodeon's top show after 15 years, and they've obviously decided to [[CashCowFranchise milk it for all its worth.]] Today, Nickelodeon's typical schedule (not counting the Creator/NickJr or Creator/NickAtNite blocks) is comprised almost entirely of either ''[=SpongeBob=]'' or ''WesternAnimation/TheLoudHouse''.
* CashCowFranchise: Within its first 10 years, ''[=SpongeBob=]'' made over 8 BILLION DOLLARS in revenue, and is no doubt still making more. In fact, it's estimated that 60% of the station's annual revenue come from ''Spongebob alone!''
** During the show's peak, you couldn't go anywhere in America without seeing something SpongeBob related. He's spawned hundreds of [[http://www.animationshops.com/sponge-bob.html T-shirts]], [[http://www.entertainmentearth.com/prodinfo.asp?number=YSSBW0200A#.WFh0_lMrKpo action]] [[https://www.amazon.com/Spongebob-Squarepants-Bikini-Squidward-Patrick/dp/B00417S8D4 figures]], [[http://www.karenandjay.com/trips/pkd702/pkd-8.jpg stuffed animals]], [[http://www.barnesandnoble.com/s/spongebob/_/N-8q8;jsessionid=52FF3D11D0DB47D1C1B988D550E3CB1A.prodny_store02-atgap06 books]], [[VideoGame/SpongeBobSquarePantsBattleforBikiniBottom video games]], [[https://www.amazon.com/SpongeBobs-Greatest-Hits-SpongeBob-Squarepants/dp/B002935GLY soundtracks]], [[https://www.youtube.com/watch?v=zbQcBeIx5Zg DVD collections]], [[http://x-entertainment.com/articles/0867/ every food item you can think of]], [[https://www.google.com/search?q=spongebob+burger+king+toys&newwindow=1&safe=active&biw=1538&bih=742&source=lnms&tbm=isch&sa=X&ved=0ahUKEwiQqsLnwYHRAhWD7oMKHRo4DFUQ_AUICSgC#imgrc=t0pVYG-LzHdA1M%3A kids meal toys]], [[http://www.funkidslive.com/events/theatre-spongebob-squarepants-the-sponge-who-could-fly-may-dates/ a touring stage show in the UK]], [[https://www.youtube.com/watch?v=P1yGmJsipqg amusement]] [[https://en.wikipedia.org/wiki/SpongeBob_SquarePants_Rock_Bottom_Plunge park]] [[https://www.youtube.com/watch?v=Jhc05wsScb8 rides]], [[http://lego.wikia.com/wiki/SpongeBob_SquarePants_(Theme) Lego sets]], and [[https://www.youtube.com/watch?v=-9qe4HPeHlA a balloon in the Macy's Parade]], that shows up almost as much as [[ComicStrip/{{Peanuts}} Snoopy]] does.
** While it's definitely not as popular as it was during the 2000's, the show still makes tons of money off of merchendise, and continues to get great ratings. Heck, [[WesternAnimation/TheSpongeBobMovieSpongeOutofWater the 2nd movie]] made over $300,000,000 worldwide. Plus it got a [[Theater/TheSpongeBobMusical show on Broadway]], [[https://www.youtube.com/watch?v=Gm-BYvBNhUE a store at Universal Studios Orlando]], [[http://spongebob.wikia.com/wiki/File:Spongebob-squarepants-happy-meal-toys.jpg Happy Meal toys]], [[http://www.strapya-world.com/products/65538.html phone cases]], [[https://s-media-cache-ak0.pinimg.com/736x/b9/d3/5c/b9d35c1e52f05acb1604db49ef3dc808.jpg Funko POP figures]], and [[http://knowyourmeme.com/memes/subcultures/spongebob-squarepants dozens of internet memes]].
* CastingGag: Flats the Flounder is voiced by Thomas Wilson, who's known for playing The Bully Biff Tannon (who also has a perchance for the word "butt") in the ''Film/BackToTheFuture'' films.
* CreatorBacklash: Creative director Vincent Waller claimed that he isn't too fond of "Dunces and Dragons". He doesn't hate the episode, but he felt it didn't benefit from its two part length and that its comedy would've been better suited to an 11 minute format.
* CrossDressingVoices:
** Patrick and Mermaid Man are voiced by Ikuko Tani (an old lady) in Japanese; Plankton, however, is voiced by Chie Matsuraa, a young woman who doesn't even try to match Plankton's English voice.
** Zig-zagged with Mermaid Man in Japan; he has been voiced by IkukoTani (Patrick), but also by Creator/RokuroNaya (Squidward) and Keijin Okuda (Mr. Krabs).
** It was played straight, but later averted with Mr. Krabs' mother. She was originally voiced by writer Paul Tibbit, but she then became voiced by Serena Irwin.
* TheDanza: In "Mermaid Man Begins", the real names of Mermaid Man and Barnacle Boy are revealed to be Ernie and Tim. Mermaid Man and Barnacle Boy are voiced by Creator/ErnestBorgnine and Tim Conway, respectively.
* {{Defictionalization}}:
** Fans on Website/FourChan's /co/ board have also [[http://24.media.tumblr.com/tumblr_m9kmr8uGjx1rrvz01o1_1280.jpg theorized]] and [[http://thechive.files.wordpress.com/2011/03/bossy-delux-9.jpg constructed]] the Double Triple Bossy Deluxe [[http://www.youtube.com/watch?v=0A67YpUs6sQ from "Pickles"]]. [[note]][[ArsonMurderAndJaywalking They forgot the pickles, though...]][[/note]]
** A real life Krusty Krab restaurant is opening [[http://www.ibtimes.co.uk/krusty-krab-iconic-spongebob-squarepants-restaurant-open-above-water-palestine-1454178 in Palestine(!).]]
* DescendedCreator:
** Potty The Parrot was voiced by series creator Stephen Hillenburg in the early episodes. Series producer Paul Tibbit soon took over.
** It was played straight, but later averted with Mr. Krabs' mother. She was originally voiced by writer Paul Tibbit, but she then became voiced by Serena Irwin.
* DevelopmentGag: Mr. Lawrence originally auditioned for the role of Spongebob, using the same voice he'd eventually use for Plankton. That deep, heroic voice Spongebob occasionally dips into? That's Creator/TomKenny imitating Lawrence's original voice for his own amusement.
* EnforcedMethodActing: Tom Kenny actually ''was'' very sick when recording Spongie's sniffly, sneezy dialogue in "Suds."
* ExecutiveMeddling:
** It has saved the show from two series finales. [[WesternAnimation/TheSpongeBobSquarePantsMovie The movie]] was intended to be a GrandFinale for the series, but the possibility was later pushed to the "[=SpongeBob=]'s Last Stand" special. The show was continued since it was very close to dethroning {{WesternAnimation/Rugrats}} as the longest running Nicktoon. It eventually did bypass the series when it aired episode 173.
** [[TVMovie Atlantis SquarePantis]] was originally [[https://twitter.com/_dolza_/status/451187862155710464 meant to be a regular 11-minute episode about [=SpongeBob=] and Patrick, but the network made them turn it into a 33-minute "movie",]] [[https://twitter.com/_dolza_/status/500143312456536064 which resulted in many of the problems most people have with the film.]]
* FanNickname: Those less than fond of the series have taken to referring to the show and its title character as "[=SpongeKnob=]".
* IronyAsSheIsCast: Music/DavidBowie as Lord Royal Highness in Atlantis [=SquarePantis=]. He's the only character that doesn't have his own musical number in that episode.
* KeepCirculatingTheTapes: The uncut version of "Just One Bite" (which includes the infamous deleted scene of the burglar alarm). It aired uncut for a while, but it was censored after a few reruns in 2002/2003 due to complaints from MoralGuardians. It hasn't aired uncut on American television (be it Nickelodeon or Nicktoons) for almost 15 years. Don't push your luck trying to find it on VHS and DVD, as they have the censored version. The only way to see it uncut is if you live in Canada or if you own an old [=VideoNow=] release of the episode.
* MissingEpisode: Due to being holiday-themed, "[[HalloweenEpisode Scaredy Pants]]," "[[ValentinesDayEpisode Valentine's Day]]," and "[[ChristmasEpisode Christmas Who?]]" only air a few times a year around their respective holidays. Consequently, the first two's sister episodes, "I Was a Teenage Gary" and "The Paper," are also rarely seen.
* NonSingingVoice:
** Ever wonder why Mr. Krabs sounds so weird when he sings in "Welcome to the Chum Bucket"? Yes, that's Creator/DeeBradleyBaker singing, not Creator/ClancyBrown though he does his own singing in all other episodes.
** Baker also subbed for Brown for the "Very first Christmas to be!" lines in "Christmas Who", since Clancy was unable to hit the high notes needed. Clancy did do his own singing for Krabs one other line in the song, though.
** Though [=SpongeBob=] often sings in his normal voice, on special occasions he shows off a fantastic singing voice that sounds nothing like him, with him being voiced by a different guest singer every time.
* TheOtherDarrin:
** Man Ray's first appearance in ''"Mermaid Man and Barnacle Boy III"'' was voiced by John Rhys-Davies. Man Ray's subsequent appearances have been voiced by Bob Joles.
** The voices of the background fish change a lot.
** In the SpongeBob video game ''Battle For Bikini Bottom'', Mr. Krabs and Mermaid Man were voiced by Joe Whyte instead of Creator/ClancyBrown and Ernest Borgnine for unknown reasons.
** Speaking of Mermaid Man, in ''Lights, Camera, Pants!'' Ernest Borgnine is again absent, being replaced by Joe Alaskey. Also in that game, [[Series/MatchGame Charles Nelson Reilly]] returned to voice the Dirty Bubble once again, having voiced him for his initial appearance in "Mermaid Man & Barnacle Boy II" (Tom Kenny has since taken over the role).
** Patrick's original German voice, Marco Kröger, was fired in 2013 after Kröger complained that he and his colleagues were getting underpaid, and he was replaced by Fritz Rott. Due to AuthorExistenceFailure, Squidward's Chinese, German, Brazilian and Japanese voice actors had to be replaced as well.
** Paul Tibbit was the original voice for Mrs. Krabs. Serena Irwin then took on the role.
** Potty was voiced by Stephen Hillenburg before Paul Tibbit took over in season 4.
* OldShame: Downplayed a little, but Casey Alexander has stated that (the guest-animated numbers aside) [[https://twitter.com/_dolza_/status/499599205581586432 "Atlantis SquarePantis" was his least favorite episode out of all the ones he worked on,]] [[ExecutiveMeddling due to how overly complicated the story became with having to service SIX character arcs, plus musical numbers.]]
* ProductionPosse: Many of the writers, artists and actors Stephen Hillenberg had become friends with through ''WesternAnimatoon/RockosModernLife'' migrated over to this show with him.
* RealLifeRelative: Karen may be married to Plankton in the show, but her voice actress, Jill Talley, is married to Tom Kenny. Unfortunately, their characters hardly ever interact with each other.
* RealLifeWritesThePlot:
** "Reef Blower" was completely pantomime because of a faulty sound system.
** Tom Kenny's acting in "Suds" wasn't just acting -- according to an interview in Nick Magazine, he was actually very sick when he recorded the dialogue.
* RecursiveAdaptation: The TieInNovel ''For the Love of Bubbles'' was [[TheFilmOfTheBook adapted into]] the episode "What Ever Happened to [=SpongeBob=]?" which was in turn [[{{Novelization}} adapted into]] the tie-in novels ''[=WhoBob WhatPants?=]'' and ''My Name is [=CheeseHead=]''.
* RecycledScript:
** A few old episodes of the show seem to have recycled plots from other Nicktoons. "Toy Store of Doom", for example, has essentially the same plot as the ''WesternAnimation/{{Rugrats}}'' episode "Toy Palace" (they get locked in a closed toy store and are afraid the toys will attack them), while "Banned in Bikini Bottom" (Krabby Patties are outlawed and Mr. Krabs starts selling them at [=SpongeBob=]'s house secretly) is similar to the WesternAnimation/CatDog episode "Just Say [=CatDog=] Sent You".
** "Picture Day" has a recycled script from an episode of a Disney show: the ''WesternAnimation/{{Recess}}'' episode "One Stayed Clean". "Big Pink Loser" is also ''extremely'' similar to "Copycat Kid".
** "Squid Defense" is very similar to the ''WesternAnimation/HeyArnold'' episode "Mugged".
** "Face Freeze" is similar to season 1 episode "Hooky", wherein [=SpongeBob=] and Patrick are tempted to do something Mr. Krabs told them not to.
* RetroactiveRecognition:
** Prior to becoming a film director, [[Film/{{Hop}} Tim Hill]] worked as a writer for [=SpongeBob=] up until 2006.
** ''WesternAnimation/PhineasAndFerb'' co-creator Dan Povenmire was a writer and storyboard artist for [=SpongeBob=] in it's first three seasons.
* ScrewedByTheLawyers: Due to issues with certain musicians leaving APM (the company [=SpongeBob=] gets its stock music cues from) over time, there are several music cues in the older episodes that can't be used in any newer episodes (i.e. Oyster Girls).
** The DVD release of "The Complete 1st Season" in particular got hit pretty hard by this. Since Nickelodeon refused to pay royalties for some of the music tracks, some episodes had some tracks replaced ("Employee of the Month", "Karate Choppers", "Sandy's Rocket", "Culture Shock", and "Rock Bottom"). And, most infamously, "Help Wanted" was not included in the boxset due to Tiny Tim's "Living in the Sunlight" playing in the climax. All of these episodes were rereleased on several compilation DVD's with the original soundtracks and "Help Wanted" was eventually released as a special feature on "The Complete 3rd Season" DVD.
* ScrewedByTheNetwork: On their Nicktoons channel, as it only airs when most people are asleep. You were probably confused when you saw this trope on this page if you don't get Nicktoons. (That's probably because they don't ''need'' to air it on Nicktoons.)
* ShrugOfGod: According to Vincent Waller, even the writers don't know what the Krabby Patty Secret Formula is and consider its details irrelevant to its purpose as a plot device. The only detail Stephen Hillenburg would give about it is that there is no animal protein in the formula.
-->"The secret Krabby patty formula is an idea, it isn't a thing."
* {{Spoiler}}: The Dish Network description for "Doing Time" is "[[AccidentalMisnaming Ms. Puff]] imagines going to jail for [=SpongeBob=]," which spoils the [[AllJustADream ending]].
* TalkingToHimself:
** Creator/TomKenny doing many additional voices can usually result in this. The episode "Gary Takes a Bath" is basically 11 minutes of Tom Kenny talking to himself.
** In the Swedish dub, there is Squidward with Squilliam and [=SpongeBob=] with his cousin Stanley.
* TropeNamer:
** IveHeardOfThatWhatIsIt
** NoMatterHowMuchIBeg
* UnCancelled: [=SpongeBob=] [=SquarePants=] initially ended production in February of 2002 on request of Stephen Hillenburg and Derek Drymon. Nickelodeon tried so hard to convince Stephen to resume production with the series but Stephen and Derek denied the option. Around 2003-2004, there were negotiations to revive the series & Paul Tibbitt agreed to step in as showrunner for the new seasons. The series went back into production in 2004 and with the completed movie finished to screen into theatres (designated to be the series finale of the original run), the show's new episodes began airing in 2005.
* UnintentionalPeriodPiece: The pre-movie episodes, especially the first season which makes references to the pre-cell phone era. Many early episodes also reference the Krusty Krab being closed on Sundays at a time where many American businesses were also doing the same thing.
* UrbanLegendOfZelda:
** There is a rumor that in "I Was A Teenage Gary", that there was a scene that depicted Squidward transforming into a snail. Vincent Waller eventually debunked the rumor on his Twitter, pointing out that the scene was never even storyboarded.
** Rumors exist that the original airing of "Hooky" featured a dead fish being strung up by his shoes.
* WhatCouldHaveBeen:
** Apparently Spike TV asked if the creator would be willing to make a DarkerAndEdgier [=SpongeBob=] show on their network, where Patrick and [=SpongeBob=] would be a gay couple, ala ''[[WesternAnimation/TheRenAndStimpyShow Ren and Stimpy: Adult Party Cartoon]]''. He declined.
** [=SpongeBob=]'s spot in the Nicktoons roster was originally meant for another cartoon, one that never happened due to the creator leaving Nickelodeon over office politics. That cartoon? ''Sniz and Fondue'' of ''WesternAnimation/KaBlam''.
** Early production sketches indicate the cast was originally human.
** [=SpongeBob=] was originally designed to resemble [[https://en.wikipedia.org/wiki/Sponge#/media/File:Aplysina_archeri_(Stove-pipe_Sponge-pink_variation).jpg an actual sea sponge]], but Stephen Hillenberg couldn't do an appealing caricature of one. He went with a synthetic sink sponge instead to give the character a "[[StealthPun squeaky clean nerd]]" appearance, as well as to imply that he's "a square peg trying to fit into a round hole."
** The creator also wanted to call him Sponge Boy until he learned the name was trademarked. This appears in a MythologyGag where Mr. Krabs says "Sponge boy, me Bob!"
** The name of the Krabby Patty was originally going to be the Barnacle Burger.
** "Reef Blower" was originally intended to have dialogue, but [[RealLifeWritesThePlot became a dialogue free episode due to the sound equipment being damaged]].
** Mr. Lawrence auditioned for the role of [=SpongeBob=], using the same voice he'd later use for Plankton.
** The show was going to have a [[https://www.youtube.com/watch?v=nvZ29ybrlBk completely different intro]] with a more action style music piece, still images, and no lyrics. The intro was later changed to fit the show's style.
** Storyboards for the controversial episode "Someone's in the Kitchen with Sandy" actually had Sandy getting naked as opposed to just [[FullyClothedNudity her bra and panties]].
** The infamous TVMovie "Atlantis Squarepantis" was originally intended to be an 11-minute [=SpongeBob=] and Patrick episode, [[ExecutiveMeddling until Nickelodeon asked the team to turn it a TV Movie about going to Atlantis, which would explain the rushed quality of the "film".]]
** The original draft of "Something Smells" had [=SpongeBob=] gaining his rancid breath from onion-flavored ice cream, but the writers decided that having it be self-inflicted was funnier.
** Barnacle Boy was originally a character called "Barnacle Bill", a salty old sailor who's body is a piece of log with his head sticking out, similar to Seamus from ''WesternAnimation/FamilyGuy''. While he never appears in the show, he's the titular character two-part comic "The Ballad of Barnacle Bill" in the [=SpongeBob=] comic.
* WordOfGod:
** Stephen Hillenburg has made it perfectly clear that [=SpongeBob=] [[{{Asexuality}} does not feel sexual attraction]]. He also adds that [=SpongeBob=] has a chaste crush on Sandy.
** In terms of the series itself WordOfGod also states that in spite of the series continuing to this day, the original team members and the Hillenburg himself say that the first theatrical movie is the end of [=SpongeBob=]'s story.
** According to Vincent Waller, Stephen does not want the subject of who Pearl's mother was to be brought up on the show.
** Vincent Waller's stance on the two different King Neptunes (the one in the series and the one in the first movie) is that they serve the same figurehead and are basically interchangeable with each other, so the staff doesn't bother distinguishing between the two.
** Vincent Waller has also stated that the video game tie-ins (i.e. ''[[VideoGame/SpongeBobSquarePantsBattleForBikiniBottom Battle for Bikini Bottom]]'') [[CanonDiscontinuity are non-canon to the cartoons.]]
* WriterRevolt: According to [[WordOfDante Mr. Lawrence]], the show was at least partially conceived out of Stephen Hillenberg's frustration over having several gags and stories he'd come up with during his tenure on ''WesternAnimaton/RockosModernLife'' get vetoed.
* WriteWhatYouKnow: In addition to his history as a marine biologist influencing the show's universe, Stephen Hillenburg based the Krusty Krab on an actual nautical-themed burger joint he worked at as a teenager, with his "old sea dog" boss serving as [[WriteWhoYouKnow the inspiration of Mr. Krabs]]. The call-and-response theme song was based on one of the restaurant's gimmicks where the wait staff dressed up as sailors and lead the children in sea shanties, usually beginning with "Are you ready kids!" to which the children were expected to respond "Aye aye, captain!"

!!Other Trivia
* For [=SpongeBob=]'s voice, Tom Kenny decided to impersonate an angry little person he met once who was [[SirSwearsALot swearing up a storm]] because [[TypeCasting he only gets auditions for Christmas commercials]]. He also added that Nickelodeon does not like him telling that story.
* Nickelodeon [[DisneyOwnsThisTrope owns the rights to Tom Kenny's SpongeBob voice]], so he is not allowed to use it for any other role.
* Believe it or not, [=SpongeBob=] was actually acknowledged by ''VideoGame/SuperSmashBros'' creator Masahiro Sakurai to be a popular request for a new playable fighter. Unfortunately, Sakurai immediately stated [=SpongeBob=] would never appear in the acclaimed MascotFighter, due to his games released outside Japan and not being originally a video game character.
