* 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.
* {{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]]
* 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. Yes, [[Film/{{Highlander}} THAT]] [[TheShawshankRedemption Clancy]] [[WesternAnimation/SupermanTheAnimatedSeries Brown]].
** 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.
* 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.
* 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"
* 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.
