* AdoredByTheNetwork: Currently Nickelodeon's top show, and they've obviously decided to [[CashCowFranchise milk it for all its worth.]]
* CashCowFranchise: Within its first 10 years, ''Spongebob'' made over 8 BILLION DOLLARS in revenue. No doubt that it's still making more.
* 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.
* 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 4chan 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 Palistine.]]
* 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.
* HeyItsThatGuy:
** Yes, that is really TomKenny you're seeing dressed up like a dime-store Halloween pirate.
** Martin Olson plays the live-action role of the Chief in "Mermaidman and Barnacle Boy V", who would later be known as [[WesternAnimation/AdventureTime Hunson Abadeer]].
* [[HeyItsThatVoice Hey, It's That Voice!]]: There are a ''lot'' of celebrity cameos, ranging from DavidBowie to Amy Poehler and even JohnnyDepp.
** Don't forget they have Creator/ClancyBrown as Mr. Krabs. [[Franchise/CrashBandicoot Yes]], [[Film/{{Highlander}} THAT]] [[Film/TheShawshankRedemption Clancy]] [[WesternAnimation/SupermanTheAnimatedSeries Brown]].
** In the "[=SpongeBob=] B.C." special, Bill Fagerbakke portrays (in live action) Cavey the Caveman, and when he speaks, one can easily tell that he's Patrick Star's voice actor. Tom Kenny averts this trope (at least in this context), as his portrayal of Patchy the Pirate sounds nothing like [=SpongeBob's=] voice.
** Before [=SpongeBob=], TomKenny voiced [[RockosModernLife other]] [[PowerpuffGirls happy-go-lucky manchilds]] from [[CatDog other animated shows.]]
** Can you imagine Sandy screaming "[[VideoGame/ResidentEvil4 Leon]]!"? There you go.
*** Cindy Vortex...
** [[Series/GoodEats Alton Brown]] as Nicky!
** [[ThisIsSpinalTap Nigel Tufnel]] appeared as [=SpongeBob=]'s cousin, Stanley.
** [[McHalesNavy Ernest Borgnine and Tim Conway]] as Mermaid Man and Barnacle Boy.
** Neptune is [[{{Seinfeld}} J. Peterman]]!
*** In the movie, he's more [[Series/ArrestedDevelopment George Sr.]]
** In "I'm With Stupid", Janet was [[WesternAnimation/PepperAnn Nicky Little]]
** The Dirty Bubble was also [[AllDogsGoToHeaven Killer]] until Charles Nelson Reilly, sadly, died in 2007. All of his appearances afterwards have him voiced by TomKenny.
** Patrick was once another [[WesternAnimation/{{Gargoyles}} gluttonous, not-so-bright comic relief character]].
*** [[WesternAnimation/LloydInSpace More than once, actually.]]
** The Flying Dutchman is [[TheMarvelousMisadventuresOfFlapjack Captain K'Nunckles!]]
** Flatts, Reg, Marty (Patrick's [[spoiler:fake]] dad) and the Tattletale Strangler are [[Film/BackToTheFuture Biff Tannen!]]
** And Man Ray was [[Film/LordOfTheRings Gimli!]] Or [[Franchise/IndianaJones Sallah.]]
** In Germany, Patchy is [[LazyTown Robbie Rotten]], Spongebob is [[FamilyMatters Steve Urkel]], and Mr. Krabs is ChuckNorris of all people!
*** [[{{Seinfeld}} Jerry Seinfeld]] appears in the German dub of "One Krabs' Trash".
*** Squidward is [[Disney/TheLionKing Zazu]]... and TalkingtoHimself with Squilliam!
** This is nothing compared to France, where Spongebob is [[{{Anime/Monster}} Johann Liebert]]. Patrick is [[DannyPhantom Mr Lancer]], and Squidward was [[WesternAnimation/SouthPark Mr Garrison]] (later [[WesternAnimation/{{Animaniacs}} Wakko Warner]]). Amusingly, Plankton and Mr. Krabs [[TalkingToHimself share a voice actor]].
** Spain has [[Series/{{Teletubbies}} Tinky Winky]] as Spongebob (this doesn't help the AmbiguouslyGay part one bit), while Patrick is [[WesternAnimation/DoraTheExplorer Dora's map]].
* 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.
* TheOtherDarrin: Man Ray's first appearance in "Mermaid Man and Barnacle Boy V" was voiced by Guy Siner and 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 was voiced by Joe White instead of Creator/ClancyBrown for unknown reasons.
** Joe White also voiced Mermaid Man in the video games, and has replaced Ernest Borgnine as Mermaid Man on the show following Borgnine's death.
* 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 [[TieInNovel 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 {{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 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".
** "Sailor Mouth" is very similar to [[WesternAnimation/{{Arthur}} "Bleeped"]], but airs ''much'' more frequently.
** "Squid Defense" is very similar to the ''HeyArnold'' episode "Mugged"
* 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.)
* TropeNamer:
** IveHeardOfThatWhatIsIt
** NoMatterHowMuchIBeg
* WhatCouldHaveBeen: Apparently Adult Swim 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 RenAndStimpy. He declined.
** Early production sketches indicate the cast was originally human.
** The creator also wanted to call him Sponge Boy until he learned the name was copyrighted. This appears in a MythologyGag where Mr. Krabs says "Sponge Boy Me Bob."
** The name of the Krusty Krab was originally going to be called 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]].
* WordOfGod: Stephen Hillenburg has made it perfectly clear that Spongebob 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.
*** As the second movie is starting to be filmed in Savannah, it's anybody's guess as to where the story stands now.
