* Apparently some fans believe that the term 'twinkle toes' was coined by ''WesternAnimation/AvatarTheLastAirbender''. [[WesternAnimation/TheFlintstones "Twinkle Toes" Flintstone]] would have something to say about that.
* Who first used HumongousMecha? Was it ''Franchise/{{Transformers}}''? The Japanese ''[[Series/SpiderManJapan Spider-Man]]''? Creator/RobertAHeinlein's ''Literature/StarshipTroopers''? The tripods from the original ''[[http://en.wikipedia.org/wiki/War_of_the_Worlds War Of The Worlds]]'' book from 1898? The [[http://en.wikipedia.org/wiki/Garuda Tale of Garuda]] from ''ancient Hindu legend'' had a robot with [[ChainsawGood rotary saws for hands]]. This one is officially one of TheOldestOnesInTheBook.
** Then there's Talos from Greek mythology, the original model for ''Dungeons & Dragons''' "iron golem".
** Myths are replete with this. Hittite mythology has one. Golden automata and other mechanical creatures were all over GreekMythology. Rabbi Loew's Golem was well-known for being large and powerful. Creating a mechanical man is a very old idea indeed, and making it huge is simply the next step up. Naturally, it's arguable which of these "count" as actual mecha, but the basic idea goes back.
* Some people associate "Whoop whoop whoop" noises with [[WesternAnimation/{{Futurama}} Zoidberg]], [[WeirdAlEffect completely forgetting]] ''Film/TheThreeStooges''.
** The DVD subtitles, at least, give "MIMICS THREE STOOGES" or "IMITATES CURLY FROM THE THREE STOOGES" rather than "WHOOP WHOOP WHOOP".
* The triangular CoolShades worn by Soundwave and Prowl of ''TransformersAnimated'' are often mistaken to be a ShoutOut to the [[MemeticMutation famous]] ones worn by Kamina of ''Anime/TengenToppaGurrenLagann'', but [[WordOfGod Derrick J. Wyatt]] said they were actually a reference to the much older ''ComicBook/ABCWarriors'' of ''2000 AD'' fame. They were also worn by several other characters before Kamina, including [[CalvinAndHobbes Calvin]] (in one strip) and Ash's [[Anime/{{Pokemon}} Squirtle]]. Many also thought the ''Lagann'' had some influence on the Headmaster design (both are robots that could become the head of another mecha to boost its power). However, besides the idea of a robot becoming a Transformer's head dating back to [[TransformersGenerationOne G1]], Wyatt stated that he'd never seen ''Gurren Lagann'' until after the first season was already done with production (though he stated that if he ''had'' seen it before, the design would probably have stubby legs and let Masterson poke his head out the top).
* Although many people think the catcall "[[HelloNurse Hellooooo, nurse!]]" was originally from ''WesternAnimation/{{Animaniacs}}'', it originated several decades ago, in vaudeville.
** As did most things on ''WesternAnimation/{{Animaniacs}}''.
*** Such as Wakko's accent, which was based entirely off Ringo Starr.
* The cars in [[http://www.youtube.com/watch?v=7pxap-M_--k&feature=related this short]] bear a certain striking similarity to ''WesternAnimation/{{Cars}}''. Thing is though, the short is actually from ''1952''!
* WoodyWoodpecker's first appearance was actually as the villain of a short of a now forgotten character called "WesternAnimation/AndyPanda". Oh, and his laugh (produced by MelBlanc) didnt start with him either. Blanc used it earlier in a few of his Warner Bros. shorts like ''Porky's Hare Hunt''.
* When ''WesternAnimation/TheSimpsons'' first aired, some viewers believed certain lines popularized by Bart to have been invented by the show's creators. These include Bart's replacing the words of "Jingle Bells" ("... Batman smells, Robin laid an egg...") in the first episode and "Eat my shorts", first said in ''TheBreakfastClub'' (1985). And while "Yo!" quite obviously predates Bart Simpson, being famously used at the ending of the first ''{{Rocky}}'' movie (1976), many Generation-Y kids grew up not knowing that.
** This is particularly ironic, as the creators note in the first season's DVD commentary, because Bart was meant as social commentary, speaking almost entirely in borrowed catch phrases and clichés. When the popularity of ''The Simpsons'' caused people to attribute the phrases to Bart instead, the joke was lost on many viewers. In fact Creator/NancyCartwright, the voice of Bart, says that she first heard "eat my shorts" when she was in high school (in the 1970s), and that it became a running gag among the fellow members of her high school marching band.
** Homer's iconic "D'oh!" outburst is from Laurel and Hardy (though in a shorter form), as [[http://www.heraldscotland.com/what-s-the-story-with-homer-s-d-oh-1.840349 confirmed]] by [[WordOfGod Matt Groening]].
** While Homer is named after creator Matt Groening's father, he also shares his name with a supporting character in Nathanael West's novella ''The Day of the Locust'', which was written in 1939. This has amused more than a few English majors.
** The title of episode 7G03 from season 1, ''[[IncrediblyLamePun Homer's]] [[Literature/TheOdyssey Odyssey]]''.
** Creator/AdamWest was AdamWesting ''seven years'' before ''WesternAnimation/FamilyGuy'' premiered.
** Many famous ''Simpsons'' episodes are direct homages to or parodies of other material, especially anything in the Halloween episodes.
* Ah, ''WesternAnimation/ToyStory''! What a cute and creative idea, the thought that toys actually come alive while their master is away. Older folks remember reading those stories when they were about good old ''RaggedyAnn''.
** ''The Velveteen Rabbit'' was slightly younger -- 1922 to Raggedy Ann's... call it 1918 -- but the doll predates the stories by a couple years. Seems older, what with the scarlet fever, and all.
*** "Literature/TheSteadfastTinSoldier" beats both of those, being first published in 1838.
*** ''Literature/TheNutcrackerAndTheMouseKing'' was written by Creator/ETAHoffmann in 1816 and turned into a ballet by {{Tchaikovsky}} in 1892.
*** Children's imaginations ''beat all of them.''
*** Read ''When Toys Come Alive'' by Lois Rostow Kuznets. She has the whole history.
* ''Disney/ThePrincessAndTheFrog'', featuring Disney's first black princess, has already been accused of trying to cash in on the Obama presidency. Anyone who follows Disney will remember this was on the drawing board years before Obama was nationally known, and the first teaser trailer was available before the Democratic primaries.
* The American ''VideoGame/{{Darkstalkers}}'' cartoon featured a bespectacled boy named Harry Grimoire who was studying magic (and happened to have Felicia as a "pet"). This would've been an obvious rip of ''Literature/HarryPotter'', if not for the fact that the cartoon came out some years before.
** A similar thing happened with ''ComicBook/TheBooksOfMagic'', which has a bespectacled young boy who is destined to be a wizard -- in fact Neil Gaiman admits that despite having a bespectacled wizard go to school wasn't his original idea, and that he and Rowling were more inspired by Arthurian legends than each other (unfortunately, a magazine MisBlamed him as having accused Rowling of ripping off his ideas, which he rebutted).
* Most Disney fans assume that MickeyMouse is Disney's first cartoon character, and Peg-Leg Pete was created to be his primary enemy. Actually, Pete was the ''very first recurring Disney character'', created in 1925 (before even ''OswaldTheLuckyRabbit'') for one of Disney's AliceComedies, a series of shorts which mixed live action and animation. Pete was always a villain, but the fact is that he was imported into the earliest Mickey cartoons to [[RoguesGalleryTransplant give Mickey an established character to fight]], not the other way around.
** For that matter, most people don't know that Mickey was an {{Expy}} of Oswald...but even fewer know that Oswald himself was an Expy of FelixTheCat.
** Pete's son, PJ, is generally thought to have been created in 1992 for ''WesternAnimation/GoofTroop''. He was actually created half a century prior, debuting in a DonaldDuck [[ClassicDisneyShorts cartoon]] called "Bellboy Donald" (though he went by Junior and he looked like MickeyMouse with cat ears), and the character is only 17 years newer than his father. However, his personality was [[CharacterizationMarchesOn the exact opposite in every way from what was to come]], so he simultaneously looked ''less'' like his father and acted (and sounded) ''more'' like him.
** Likewise, Goofy's son, Max, was created as "Goofy Jr." in 1951 in the Goofy short "Fathers Are People", but also had extensive changes done to his personality and design. Though the personality changes weren't ''as'' extreme as PJ's (Max kept his wild side, he just gained a serious side too), the appearance changes were ''more'' extreme (originally "Goofy Jr." was a redhead with a pink nose and no ears).
* There used to be a very vocal faction at the [=IMDb=] forums which reckoned that "all of [=DreamWorks'=] ideas were stolen from Pixar" (yes, '''''all''' of them''). At least two of their favorite examples were shown to be nonsense, as they were in production years before and only bore a superficial resemblance, and in any case one of them (''WesternAnimation/FlushedAway'') was actually an AardmanAnimations movie -- the [=DreamWorks=] involvement was minimal.
* Spoofed in the "Springfield Shopper" booklet that comes with the ''Simpsons Movie'' DVD; in it, Homer (as a movie critic who's ''way'' behind with his column) describes ''Star Wars'' (by which he means ''ANewHope'') as being "a parody of ''Film/{{Spaceballs}}''".
* An animated action series with a FieryRedhead ActionGirl whose blond male sidekick and a VoiceWithAnInternetConnection help her pursue a hot former crimefighter with long black hair who turned to crime ForTheEvulz because she was bored being a good guy. What? What is this "WesternAnimation/KimPossible" you speak of? It's ''WhereOnEarthIsCarmenSandiego''.
** You know, Kim Possible? The [[BuffySpeak slang-happy]], petite, fashion-forward cheerleader who [[ActionGirl fights bad guys]] and occasionally saves the world while trying to maintain a normal social life, with the help of her two classmates, a [[CoolLoser nerdy]] computer hacker and an [[ButtMonkey ineffectual goofus]] with HiddenDepths who's secretly in love with her? They occasionally butt heads with the [[AlphaBitch bitchy rich girl]], or Kim's [[DarkActionGirl snarky brunette]] [[ShadowArchetype nemesis]] who defected from the good guys to [[TheDragon hench]] for a perky villain-. No, wait, I was thinking of Series/BuffyTheVampireSlayer.
* Now and then someone will accuse ''ThundarrTheBarbarian'' of being a ripoff of ''WesternAnimation/HeManAndTheMastersOfTheUniverse1983'', despite the fact that ''Thundarr'' predates ''He-Man'' by several years.
* To this day, there are still fans of the ''WesternAnimation/TeenTitans'' cartoon who are surprised when they find out the cartoon was preceded by the ''Comicbook/TeenTitans'' comic book by ''41 years''.
* In one episode of ''WesternAnimation/{{Recess}}'', Gus is involved in a plot against the Ashleys wherein he claims Ashley is also his name - insisting that it's not that unusual in the progressive 1990s. In reality, "Ashley" was almost solely a boy's name until the early 20th century; it was perfectly acceptable for a boy to be named Ashley ''over a hundred years'' before the episode was written or aired.
** One of the best known examples ''in pop culture'' would be Ashley Wilkes of ''GoneWithTheWind'', a film consistantly put in top 10 lists.
*** Which was a best-selling ''book'' first.
** Another one people here may be familiar with is [[BruceCampbell Ashley "Ash" Williams]] of ''Franchise/EvilDead'' fame.
* Here's one: ThePollyanna type in a place that is quite clearly {{Hell}}, run by a creature that is quite clearly {{Satan}}, who acts as a CorruptCorporateExecutive. No, not ''{{Jimmy Two-Shoes}}'', but an earlier show called ''TheBaskervilles''.
* You know that routine on ''APupNamedScoobyDoo'' that Shaggy and Scooby-Doo had. Shaggy makes an IncrediblyLamePun. Scooby-Doo laughs, then says, "I don't get it." It comes from ''Hang in There, Scooby-Doo'' on ''The ScoobyDoo/Dynomutt Show''. The gang had found a cassette of rock music in the cavern.
-->'''Shaggy:''' Those cave teenagers love their rock music?
-->'''Scooby-Doo:''' (laughs) I don't get it.
* On a larger scale, a lot of baby boomers who grew up in TheSixties, if they have no knowledge of animation history, will be surprised when you tell them that cartoons from TheGoldenAgeOfAnimation such as ''WesternAnimation/LooneyTunes'' and ''WesternAnimation/TomAndJerry'' were coming out in the 1930s and '40s, and were already decades old back when they remember watching the cartoons on Saturday mornings.
* Creator/AdamWest as Catman is a parody of Series/{{Batman}} in ''WesternAnimation/TheFairlyOddParents''. However, there actually is a Catman which is a Batman villain created in the '60s.
** And the crazy paranoid Adam West in ''WesternAnimation/FamilyGuy'' made his first appearance in an episode of ''JohnnyBravo''.
*** And that's an interesting case because, before creating ''WesternAnimation/FamilyGuy,'' SethMacFarlane worked on ''JohnnyBravo.''
* The expression "Cowabunga!" did NOT originate on ''WesternAnimation/{{Teenage Mutant Ninja Turtles|1987}}'' (or even the surfer/skater culture they were imitating). The phrase originated from "The Howdy Doody Show" (1947-60), spoken by Chief Thunderthud, the Indian founder of Doodyville.
* Judging from its sheer presence on the internet, it's a fair assumption that the ''MyLittlePony'' franchise never caught on with males until ''WesternAnimation/MyLittlePonyFriendshipIsMagic'', but there were bronies (not that they ''called'' themselves that) back as far as Generation 1 - believe it or not, the G1 cartoon series usually dealt with boy-friendly epic fantasy adventures, not stereotypically girly fare. But since 4Chan wasn't around in TheEighties, the male fans of the show didn't make themselves known as a significant PeripheryDemographic until the latest series.
** The infamous "Rainbow Dash always dresses in style" quote is usually associated with G3.5 (as is the theme song the lyric appears in), but the quote - and the song - were actually borrowed from G3.
** Actually, who here remembers the ''first'' time we saw multi-colored equines dancing across the screen in WesternAnimation. You know, small unicorns dancing around, and pegasi too. What, TheEighties? No...we saw these as early as TheForties - I'm talking about the Pastoral in ''Disney/{{Fantasia}}''.
** The whole "Adult men enjoying a show for girls? It's the end times/turning point for masculinity/insert flimsy sociological viewpoint here" makes you wonder if everyone has forgotten ''Anime/SailorMoon'' was originally for a similar demographic.
** Similarly, ''Friendship is Magic'' is hardly the first time a MerchandiseDriven franchise targeted solely towards little girls was adapted into a story-driven animated series with only superficial girly elements that could be (and was) enjoyed by both genders. ''WesternAnimation/SheRaPrincessOfPower'' beat it to that honour in 1985.
* ''"The Merry-Go-Round Broke Down"'' did NOT originate with ''WesternAnimation/LooneyTunes'', It even has its own lyrics that are different than the ones Daffy sing. [[http://www.youtube.com/watch?v=MOg2wL9W_Vs Here is a link to a youtube video with people singing the (slightly modified for gender) original lyrics]].
* Ultimate Spiderman been getting a lot of flack from the FanDumb for being LighterAndSofter getting multiply improbable crossovers and where spidey faces foes not in his RoguesGallery where in any other story , he would get killed. They probably never heard of [[http://www.spiderfan.org/comics/title/spiderman_super_stories-2.html Spidey]] [[http://notthebeastmaster.typepad.com/weblog/2004/03/hey_kids_death.html Super]] [[http://goodcomics.comicbookresources.com/2010/06/14/i-lova-ya-but-youre-strange-2/ Stories]]
* Remember that one episode of ''WesternAnimation/FamilyGuy'' where Peter sang "Surfin' Bird"? Turns out the idea of using that song in a cartoon has been done before — a cover was used for the short-lived Creator/{{CBS}} cartoon ''WesternAnimation/{{Birdz}}''.
** ''FamilyGuy'' causes a honking crapload of these sorts of errors thanks to its ReferenceOverdosed nature. Any film or TV show clip later parodied on ''FG'' will have hundreds of comments on YouTube mistakenly asserting the video is a reference to ''Family Guy'', even if the age of the clip makes it obvious that it originated decades before Seth [=MacFarlane=] was even ''born''.
** The "Do you remember [X]? Pepperidge Farm remembers." joke from the episode "Hell Comes to Quahog" had also been done in the ''WesternAnimation/{{Futurama}}'' episode "A Fishful of Dollars" seven years earlier, which made many say TheyCopiedItSoItSucks.
* Pop quiz: what was the first animated series about a teenager from a primitive society who is granted a magical weapon that, when he holds it above his head, grants him super-strength and transforms his pet into a fierce animal sidekick, and it features a character named She-Ra? If you guessed ''WesternAnimation/HeManAndTheMastersOfTheUniverse1983'', you're wrong - that honour goes to Creator/HannaBarbera's ''The Mighty Mightor'', created in ''1967''.
* A lot of Internet commentators accused the GravityFalls short "Hidebehind" of ripping off the SlenderManMythos-- being apparently unaware that the Hidebehind is a much older folkloric creature.
