-->-- '''Joel [=McHale=]''', ''TheSoup''

Classics, almost by definition, are works that are considered to be of high quality, are influential on later works, and are widely known. However, one will often find that only scholars and enthusiasts have first-hand knowledge of the material in question, and that the masses know it either only by title or by homages, parodies, direct references and allusions found in more populist works. Essentially, various bits and pieces of high culture are most widely known through their use in pop culture. Ill-informed people might even think these bits and pieces are original to the popular work, AndThatsTerrible ([[SturgeonsLaw nine times out of ten]]).

PietaPlagiarism exists because of this phenomenon. Most artists would be copying some other usage than the sculpture.

Frequently results in BeamMeUpScotty, ItWasHisSled, and CoveredUp.

!!Examples:

[[foldercontrol]]

[[folder:Anime/Manga]]
* Fans of ''Anime/NeonGenesisEvangelion'' can generally sing along with "Fly Me to the Moon" without knowing the original artist, or even one of the dozens of famous American artists who covered it in the four decades before NGE came out.
* [[PuellaMagiMadokaMagica The "Kyuubey's Face" shots]] - where all you see are his eyes, with the background being the color of his skin - where actually first used for Kero in CardCaptorSakura.
[[/folder]]

[[folder:Comedy]]
* [[MarxBrothers ''A Night at the Opera'']] has ruined ''Il trovatore'' for many people. Just ''try'' to hear the Anvil Chorus without thinking of Chico and Harpo after you've seen it...
-->"A ''battleship'' in ''Il trovatore''?!!
* The "Mah Nà Mah Nà" song does not originate from ''TheMuppetShow'', or even ''Series/SesameStreet'', but rather [[http://www.imdb.com/title/tt0063660/ an Italian mondo documentary film set in Sweden]].
* Mussorgsky's ''Night on Bald Mountain'' has unfortunately become known as either the theme music for a comic nemesis, or that scene in ''Disney/{{Fantasia}}'' that scarred generations of children.
** Hey, they stole that from ''VideoGame/EarthwormJim''!
** The opening was used in the Maxell "Break The Sound Barrier" ad.
* "Countin' the Beat" by the Swingers is known to a generation of Australians as the UsefulNotes/{{Kmart}} theme song.
* Many talk shows cause this, from Radio/RushLimbaugh with "My City Was Gone" by Music/{{Pretenders}}, to Rachel Maddow with "Stealing the Stock" from the ''OceansTwelve'' soundtrack.
* The song called "The Merry Go Round Broke Down" created by Cliff Friend and Dave Franklin is better remembered as the music for the WesternAnimation/LooneyTunes theme song, WesternAnimation/DaffyDuck sings a more complete version of the song with different lyrics in "Daffy and Egghead".
* Eddie Cantor's "Merrily We Roll Along" is better remembered as the [[WesternAnimation/LooneyTunes Merrie Melodies]] theme.
[[/folder]]

[[folder:Comic Books]]
* This might be happening to Franchise/{{Batman}}, if Website/YouTube comments are to be believed.
-->'''Random viewer on the Joker from WesternAnimation/BatmanTheAnimatedSeries:''' That's not the Joker, he doesn't even have [[Film/TheDarkKnight the scars]]!
** A lot of people forgot or don't realize that the Joker was based on [[http://anyeventuality.files.wordpress.com/2007/08/themanwholaughs.png Conrad Veidt's]] character in the 1928 movie TheManWhoLaughs.
* ''DonaldDuck'' (& Co.). ''The Disneyverse'' is simply ''filled'' with retold classics, movie and music references and the like, providing lots of kids their first contact with greek myths, Shakespeare's plays, classical history, etc.
[[/folder]]

[[folder:Film]]
* The 1925 Russian film ''Bronenosets Potyomkin'', usually called ''Film/BattleshipPotemkin'' in English-language sources, is generally considered hugely influential on later cinema. There is a particular scene set on some stairs leading down to the harbour in Odessa which has been imitated several times, including in ''Film/TheUntouchables'' and one of the ''[[Series/PoliceSquad Naked Gun]]'' films. It is reasonable to assume that, in modern times at least, more people who are not cineasts will have seen these homages/parodies than have seen the original film.
* By now, a notable percentage of the people who reference ''Film/CitizenKane'' as a cinema classic and could recognize the opening scene from any one second of footage have actually never seen the film and wouldn't be able to identify any other line, shot or sequence from the whole movie ([[ItWasHisSled okay, maybe one]]).
* People these days seem to think that "KlaatuBaradaNikto" is that funny nonsense line from Sam Raimi's horror comedy ''[[Franchise/EvilDead Army of Darkness]]'' (1992) (aka ''The Franchise/EvilDead 3''). Actually, it's from the black-and white sci-fi classic ''Film/TheDayTheEarthStoodStill1951'', where the sentence is used to stop Gort, the powerful invincible robot of the alien Klaatu, from destroying the Earth as punishment for the humans killing his peaceful master.
** Connoisseurs of sci-fi action figures will recognize "Klaatu," "Barada," and "Nikto" as the names of three 1983 ''StarWars'' toys, modeled after three of Jabba the Hutt's henchmen from ''Return of the Jedi'' [[AllThereInTheManual (who are never actually named on screen)]].
* As famous as the 1932 classic ''Film/{{Freaks}}'' is, many more people are familiar with the parodies and allusions to its "One of us! One of us!" scene out of context. What's more, in these parodies, the phrase often comes off as ''threatening'', the direct opposite of how it's played in the film (although the recipient sees it as such).
* Due to his habit of [[SatireParodyPastiche pastiching]] rather obscure movies, Creator/QuentinTarantino is perhaps responsible for more Popcultural Osmosis than any other mainstream filmmaker.
* "Badges? We don't need no stinking badges!" Despite being quoted ([[BeamMeUpScotty albeit, incorrectly]]) and parodied in pop culture for decades, most people have no idea this line is a reference to the HumphreyBogart film ''The Treasure of the Sierra Madre'', often attributing its origins to ''Film/BlazingSaddles'' instead. However, without the understanding that the line in the latter film is intended to be a parody of the former, the joke itself does not make sense. (The actual, original quote from the film goes, "Badges? We ain't got no badges. We don't need no badges! I don't have to show you any stinkin' badges!")
* The new ''Film/StarTrek'' movie has instantly recognizable [[PowerTrio characters]], themes and objects -- even for those who have never seen a ''Franchise/StarTrek'' episode in their life.
* Many people associate the line "I have come here to chew bubblegum and kick ass...and I'm all out of bubblegum." with VideoGame/DukeNukem rather than with "Rowdy" RoddyPiper's character in ''TheyLive''.
* The Valkyries rode helicopters (Creator/FrancisFordCoppola's ''Film/ApocalypseNow'', Creator/RichardWagner's "Music/RideOfTheValkyries"). Also, the famous scene in ''Apocalypse Now'' where Colonel Kilgore says, "I love the smell of napalm in the morning.", is actually a lot longer than people care to remember making it a cause of BeamMeUpScotty.
* There probably aren't that many people who, thanks to ''Disney/{{Fantasia}}'', wouldn't think of dinosaurs when listening to "RiteOfSpring".
* That song that everybody associates with clown cars and elephants? The one that goes doot-doot-doodle-doo-dah-doot-doot-doo-dah? ''Enter the Gladiators''.
-->'''Hypothetical Roman announcer at the Coliseum''': And now, in this corner, Brutus the ''Destroyer!'' (calliope music)
* Any time-lapse footage of city life is likely to be a reference to ''{{Koyaanisqatsi}}'', either directly or indirectly.
* You know how the canonical sound of [[FrickinLaserBeams lasers firing]] is a sort of "pew pew pew" effect? You can thank Ben Burtt, the audio designer for ''StarWars'', for that. The original sound effect was created by holding a microphone up to a taut wire while hitting the other end.
* ''Franchise/FridayThe13th'': Lots of Jason Voorhees [[{{Expy}} expies]] and parodies have [[HockeyMaskAndChainsaw a hockey mask and a chainsaw]], despite the "real" Jason not putting the mask on until [[Film/FridayThe13thPartIII the third film]] of the series, and never once using a chainsaw, which probably comes from ''Franchise/TheTexasChainsawMassacre''.
* Mike Myers' line "You put the wrong [=emPHAsis=] on the wrong [=sylLAble=]" is the one and only reason View From The Top has any kind of lasting pop cultural significance.
* ''Film/{{Casablanca}}'': HumphreyBogart [[BeamMeUpScotty never says]] "Play it again, Sam."
* Creator/QuentinTarantino put a ShoutOut to the French movie ''BandOfOutsiders'' when John Travolta and Uma Thurman's characters dance in ''Film/PulpFiction'' - however, this has spawned other parodies and IMDb says "someone dances like Travolta" under movie connections.
* PeterLorre's voice is recognizable, even to those who have never seen any of his movies. This is due ([[HeyItsThatGuy aside from his unique appearance]]) to his caricature being used in a number of LooneyTunes shorts.
* [[http://www.guardian.co.uk/film/filmblog/2007/aug/07/howthemuppetsmadeusallbergmanexperts This article]], referencing an utterly hilarious [[TheMuppetShow Muppet Show]] [[http://www.youtube.com/watch?v=Mqv_qYBgEk0 sketch]], is all about how parodies of Creator/IngmarBergman films are immediately recognizable, such as ChessWithDeath, even by people who have never watched any of his films.
* If you showed most people today stills from ''Film/TheCabinetOfDrCaligari'', they'd think it was some sort of Creator/TimBurton thing. See LooksLikeCesare.
* The word "inception" means the beginning or creation of something. Ever since [[{{Inception}} the film]], it's more often used to describe something that's inside something else of the same nature.
* ''{{Psycho}}'' - PsychoShowerMurderParody.
* Most people may recognize Pete Postlethwaite's speech at the end of ''Film/BrassedOff'' from the start of the album version of Music/{{Chumbawamba}}'s BlackSheepHit "Tubthumping".
* The infamous "YOU ARE TEARING ME APART, LISA!" line from ''Film/TheRoom'' was actually done as an homage to ''Film/RebelWithoutACause''. Most people don't know this, and think that it originated in ''The Room''. Additionally, the comments sections of most [=YouTube=] uploads of the ''Rebel Without A Cause'' scene are flooded with references to ''The Room''.
* Many people associate scarecrows in media with ''Film/TheWizardOfOz''. A good example is [[http://www.toonarific.com/show.php?show_id=2249 this website]].
** People tend to associate the quote "How do you like them apples?" with ''Film/GoodWillHunting'', when it actually was first used in The Wizard of Oz.
[[/folder]]

[[folder:Literature]]
* Literature/TheBible is the grand-daddy of this trope, with sayings like "there's nothing new under the sun" and references to Pillars of Salt and the like existing in almost every medium, though very few people have actually read the Book in question (people who go to Church will have heard excerpts). Saying religious things in Jacobean English, with lots of "thees" and "thous," comes from the King James Bible.
* "April is the cruellest month" comes from Creator/TSEliot, ''Literature/TheWasteLand''
* Behind Creator/{{Shakespeare}} and the Bible, Mary Shelley's ''Literature/{{Frankenstein}}'' is probably the biggest sufferer of this trope. The novel draws heavily on contemporary Gothic horror, feminist theories, and ''Literature/ParadiseLost''. And yet when most people think of Frankenstein...
--> "[[http://www.cracked.com/article_17221_6-writers-who-accidentally-crapped-out-masterpieces_p2.html The book's influence could have ended there, but film was invented soon afterward and directors scrambled to pour cash into Frankenstein-themed special-effects extravaganzas, bastardizations of Shelley's work that reached their pinnacle in 1931, when Universal Pictures released Frankenstein, ensuring that Shelley's well-spoken, tortured creature would be forever remembered as a bumbling green retard through countless film adaptations thereafter]]."
** Frankenstein's monster's skin color is referred to as yellow (jaundiced) in the novel.
* It's impossible to list all the comic books, novels, fantasy horror movies, roleplaying games, video games, fantasy/Sci-Fi art and music videos that feature blatant rip-offs, allusions, homages, parodies or additions to Creator/HPLovecraft's CthulhuMythos tales.
** Most people nowadays likely associate Arkham Asylum with Franchise/{{Batman}}.
** ''ProblemSleuth'' and ''Webcomic/{{Homestuck}}'' both feature monsters that clearly resemble Lovecraft's elder gods. The author, Andrew Hussie, has outright stated that he's never read a word of Lovecraft, and based his monsters entirely on secondhand references to the Cthulhu mythos.
* You've probably encountered the tropes the ''HoratioHornblower'' series popularized long before you ever heard of the series itself.
** And that obscure little work of fiction got a ShoutOut in the episode "Smile Time" of Series/{{Angel}}, with a purple stuffed thing that communicates via a horn on its face named Ratio. It's likely you didn't get the joke.
* "Ask not for whom the bell tolls." You've heard that pithy phrase, usually said when someone else is in trouble, but who said it? How about "No man is an island" ? Well, they both came from the same paragraph of the the same essay, but missing the context.
-->"No man is an island, entire of itself; every man is a piece of the continent, a part of the main. If a clod be washed away by the sea, Europe is the less, as well as if a promontory were, as well as if a manor of thy friend's or of thine own were: any man's death diminishes me, because I am involved in mankind, and therefore never send to know for whom the bell tolls; it tolls for thee."
--->--Excerpted from ''Meditation XVII'' by Creator/JohnDonne (1623 - he was contemplating his own death at the time)
* The JekyllAndHyde trope is significantly more popular than ''Literature/TheStrangeCaseOfDrJekyllAndMrHyde'', the novel that spawned it. When many people think of Jekyll and Hyde, their notions are colored by the adaptations -- including "adaptations" like ''TheIncredibleHulk''.
* ''Franchise/TheHitchhikersGuideToTheGalaxy'' - 42 is the Answer to The Ultimate Question of Life, the Universe, and Everything.
* ''Literature/{{Casabianca}}'': "The boy stood on the burning deck/Whence all but he had fled..."
* Many associate "The game's afoot" with SherlockHolmes, but it's actually from ''HenryV''
* Most of Creator/LewisCarroll's songs and rhymes in the ''Literature/AliceInWonderland'' books were parodies of once-common Victorian standards which, with the exception of "Twinkle, Twinkle Little Star" and the possible exception of "The Spider and the Fly", are considered obscure trivia by most modern readers.
* Most people know the phrase "water water everywhere but not a drop to drink", but hardly anybody knows that it came from Samuel Coleridge's ''Literature/RimeOfTheAncientMariner'' or that the original wording was "nor any drop to drink".
* ''Literature/HansBrinkerOrTheSilverSkates'': Everyone knows the tale of the little boy who prevented a flood by sticking his finger inside a dyke, except that—you know what?—it's a StoryWithinAStory.
* Used for a joke in the ''Literature/ConfederationOfValor'' series. The Taykan species are SpaceElves. Thanks to popcultural osmosis from humans, they're well aware of their physical similarity to classical elves and apparently find the comparison amusing: Torin Kerr once met a di'Taykan named [[Literature/TheLordOfTheRings Celeborn]].
* ''OfMiceAndMen'' is clearly about a big guy named Lenny and a little guy named George, and absolutely nothing else, if all the references to those characters in various sources is any indication.
* Literature/TheSatanicVerses: Most people know more about the blasphemy controversy around this novel than that they've actually read it. Including many Muslim fundamentalists who want Creator/SalmanRushdie dead.
[[/folder]]

[[folder:Live-Action TV]]
* ''Series/MontyPythonsFlyingCircus'' has done a similar takeover of John Philip Sousa's march ''The Liberty Bell''.
* ''Series/IronChef'' fans may not realize the original theme music, and indeed much of the incidental music, was from the movie soundtrack for ''Film/BackDraft''.
* Pop culture even has a habit of obscuring itself. Adam Savage of ''Series/MythBusters'' is frequently credited for the quote, "I reject your reality and substitute my own!" Actually, the line originated from the 1985 SoBadItsGood film ''The Dungeonmaster'' (Ragewar outside of the US).
* More people know [[Series/TheAdventuresOfBriscoCountyJr "The Ballad of Brisco County, Jr."]] from NBC's coverage of the Olympics than from the original show.
* Most people not familiar with ''Franchise/PowerRangers'' will simply refer to characters as "The Red Ranger" and "The Pink Ranger" etc. What they don't realise is that, as of February 2013, there have been no less than 26 different Red Rangers, with many more off-screen, and a few more debatable ones.
* ''Series/TheTwilightZone'' is better known through parodies these days to the point where many people know the endings to famous episodes without ever seeing them.
[[/folder]]

[[folder:Music]]
* ''Everything'' by JohnPhilipSousa has become used in commercials and TV shows without much understanding behind them. Most notably the ''The Washington Post March'' and ''The Stars & Stripes Forever''.
** However, ''The Liberty Bell March'' is automatically associated with Creator/MontyPython and their [[Series/MontyPythonsFlyingCircus Flying Circus]]. No exceptions.
* A large proportion of British people hearing In The Hall Of The Mountain King would be surprised to find out that it wasn't, in fact, written as the Alton Towers theme song.
** Or the in-game music to ''ManicMiner''.
** Or the theme to the syndicated ''AdventuresOfSonicTheHedgehog'' cartoon.
** Or scene music from a certain ''Manga/AstroBoy'' episode.
** Or the song that PeterLorre whistles when he goes hunting little kids in [[Creator/FritzLang M]].
** Or [[AdventuresOfSonicTheHedgehog Dr. Robotnik's lair]]
** Worse yet, one dance remix of "In The Hall of the Mountain King" has been [[MisattributedSong miscredited]] on file-sharing services as a remix of the ''InspectorGadget'' theme, despite there being only a very vague similarity between the two songs.
** The song was, in reality, written by Norwegian componist Edvard Grieg, to a scene in HenrikIbsen's play PeerGynt.
* Similarly, the first movement of Beethoven's ''Moonlight Sonata'' is better known to many 8-bit-era gamers as "the title music to ''VideoGame/JetSetWilly''".
* Play the Russian folk song "Korobeiniki" to anyone in the world, except Russians, and they are almost certain to identify it as video game music. Specifically, the ''VideoGame/{{Tetris}}'' theme.
* The song "Anything Goes" actually does not come from ''Film/IndianaJonesAndTheTempleOfDoom''. It's an authentic show tune of the period (from a Cole Porter musical of the same name) and, by the way, normally sung in English.
** And the lyrics were written by Creator/PGWodehouse.
** Show tunes may be better known in the UK, if only through airplay on the top-rated [[TheBBC BBC]] Radio 2.
** ''VideoGame/{{Fallout 3}}'' uses "Anything Goes" (and many others) to establish ITS AlternateHistory [[AfterTheEnd post-apocalyptic]] setting.
* Likewise, "Puttin' on the Ritz" did ''not'' originate from ''YoungFrankenstein''. Similarly, its [[SuspiciouslySimilarSong close musical cousin]], concerning the naming history of Istanbul, was not originally by TheyMightBeGiants.
** For that matter, "Puttin' on the Ritz" was ''not'' originally performed by Creator/FredAstaire he just sang it in BlueSkies.
*** In case you were wondering it was originally performed by HarryRichman in the film of "Puttin' on the Ritz" (you would think the name was a dead give away).
** You mean, [[CoveredUp it wasn't an]] [[TheEighties '80's hit]] by Taco?
* Many people know the "Love Theme" from Tchaikovsky's ''Romeo and Juliet Fantasy Overture'' only from its use in innumerable TV shows (WesternAnimation/SouthPark, TheFreshPrinceOfBelAir) and movies (''Wayne's World, Clueless'') to show that someone has fallen in LoveAtFirstSight.
** Oh! You mean the romantic kiss song from the first ''VideoGame/TheSims'' game?
* Just try listening to "Hoedown" from Aaron Copland's ''Rodeo'' without thinking "Beef: It's What's For Dinner."
** Or Emerson, Lake And Palmer.
* The BBC's use of Booker T. & The [=MGs=]', "Soul Limbo". Also known as the Cricket music.
** Fleetwood Mac's outro to "The Chain", otherwise known as the Formula One Racing music.
* ''Film/SinginInTheRain'' did this to most of the songs in the movie, most notably the title tune which was a standard song to be sung by aspiring actors in film in the '20s, '30s and '40s.
** Considering the film's producer, Arthur Freed, wrote or co-wrote MOST if not all of those songs for MGM in the post-sound era of film and commissioned the screenwriters to base a musical around that catalogue, it doesn't necessarily remove those songs from their original context.
* Ke$ha's "Take it Off" is a pop version of "The Streets of Cairo" (usually associated with snake-charming in pop-culture).
** ''Istanbul Not Constantinople'' made good use of its signature five-and-seven.
* Like the aforementioned ''Smoke on the Water'' by DeepPurple, there are some other classic rock songs with their sound familiar to a lot of "uninitiated" people by exposure through radio, commercials etc. Tracks like ''Break On Through to the Other Side'' by Music/TheDoors, ''Jammin'' by Music/Bo Marley, ''Born to Be Wild'' (from the soundtrack of the film ''Film/EasyRider'') by Music/{{Steppenwolf}}.
* Know what the song "Spybreak!" sounds like? [[MemeticMutation What if I told you you]] it's the song that plays during the lobby shootout scene in ''Film/TheMatrix''? If you already did, did you even know who the Propellerheads were before you did the research? Said movie came out two years after the song.
* The song [[http://www.youtube.com/watch?v=ZThquH5t0ow "Surfin' Bird"]] by The Trashmen has been greatly popularized through its use in other shows:
** It was played in the ''WesternAnimation/FamilyGuy'' episode "I Dream of Jesus". Just take a look at [[http://www.google.com/trends?q=surfin+bird this graph]].
** That small peak in 2004 coincides with the release of ''VideoGame/{{Battlefield}} Vietnam'', which for a fair few gamers might be the thing they associate with the song.
** Pee-wee Herman performed it in ''BackToTheBeach''.
** Spanish speaking viewers however may have found out about the song earlier back when it was sometimes played during the credits of ''Ah, qué Kiko'' (a spinoff of ''Series/ElChavoDelOcho'').
** And the two people who watched CBS's saturday morning lineup in the 1998-99 season would know it from ''WesternAnimation/{{Birdz}}''.
* How many people under 25 or so can hear "The Final Countdown" without thinking of ''Series/ArrestedDevelopment''?
** People from the Detroit Area have a different reaction to The Final Countdown, mostly identifying it as "The Pistons Intro Song."
** ''VideoGame/SaintsRow2'' fans will identify it as that awesome 80s song that will never, ever, ever, ever leave their head.
** Also used in ''HowToKillAMockingbird''.
* Utter the line "Right here, right now", and nearly anyone with associate it with Fat Boy Slim's song of that name, not the movie (''StrangeDays'') it's sampled from.
** Or the [[http://www.youtube.com/watch?v=7z6dxQVhE8o Jesus Jones hit]].
* For a certain generation in Britain, the lyrics to ''O Sole Mio'' will forever be "Just one Cornetto! Give it to meeeeee!"
** "[[ElvisPresley It's now or never, come hold me tight...]]"
* Many Americans are undoubtedly familiar with "Hail, Hail, the Gang's All Here." Considerably fewer might be aware of the fact that the tune is from a ''Pirates of Penzance'' ditty called "Come, Friends Who Plow the Sea."
* The "Polovetsian Dances" from Alexander Borodin's opera ''Prince Igor'' tend to be more commonly associated with ''Kismet'' and a certain Pine-Sol commercial these days.
* Zillions of certain musical lines, hooks, beats and intros have been sampled and covered so much that you would be surprised to know how old these songs are.
* The nursery tune "Pop! Goes The Weasel" was originally a piece of ''dance'' music that was popular in London dance-halls and American stage acts in the 1850s, and as a playground singing-game for kids dancing in circles. Nowadays, it's irrevocably associated with Jack-in-the-Boxes, to the point where such a toy playing any ''other'' tune feels like a SubvertedTrope.
* AlsoSprachZarathustra.
* "Always Look On The Bright Side Of Life" has become such a popular standard that some first time viewers of Film/MontyPythonsLifeOfBrian will laugh when the characters sing this song, because they assume the Pythons are simply covering a well known song. In reality it was completely written by Python member Eric Idle.
[[/folder]]

[[folder:Mythology]]
* Happens to NorseMythology. No, Loki is not Thor's brother (techniacly he is Thor's uncle) nor he is he the ultimate evil (his wickedness [[DependingOnTheWriter depends on where and by whom the myth was recorded]]) nor is he WoobieDestroyerOfWorlds. Loki is not a "god of fire", in fact the sources does not openly state what the Norse gods actually are gods of, while the patronage of certain gods like Thor is obvious, others are not. Thor is also not stated to be blonde, the closest thing to any sort of indicator of apperance is the kenning (nickname) "Red-Thor" which supposedly points to that Thor is a ginger (you are screwed SouthPark). The term "ice giants" or "frost giants" where never used by Norse pagans, they sometimes refered to certain giants as "Hrimthurses" (''Frost thurses'').
[[/folder]]

[[folder:Newspaper Comics]]
* ''ComicStrip/CalvinAndHobbes'': In the 10th Anniversary Collection, Bill Watterson admits that he's "not at all familiar with FilmNoir or detective novels", so the stories featuring Calvin's HardBoiledDetective alter ego Tracer Bullet are "just spoofs on the clichés of the genre."
[[/folder]]

[[folder:Professional Wrestling]]
* Or "The Final Countdown" without thinking of [[Wrestling/RingOfHonor Bryan Danielson]]--er, I mean [[Wrestling/{{WWE}} Daniel Bryan]]--or Wrestling/SaraDelRey.
* "Music/FlightOfTheValkyries"? Oh, you mean Daniel Bryan's current theme music, right?
* The tropes of HulkHogan are familiar to millions (perhaps even billions!) of people who have never watched a single wrestling match - particularly Hogan's ultra-macho manner of speaking and shirt-ripping.
* Many people are not aware that the catchphrase "It couldn't have happened to a nicer guy" was popularized by Buddy Rogers, the original "Nature Boy" before Wrestling/RicFlair [[BeamMeUpScotty (although Rogers never actually said it that way)]].
[[/folder]]

[[folder:Radio]]
* An example so classic, jokes about it pre-date the concept of this trope: a wit from the 1960s noted this definition of a "longhair" (a person of culture): "he can hear the William Tell Overture and not think of the Lone Ranger." The piece of music referred to is from the Rossini Opera ''William Tell''. The dramatic fanfare and thundering string section from the overture was used as the theme music for ''TheLoneRanger'' radio drama and then in movies and on television.
** On the subject of the Lone Ranger and William Tell, [[http://www.youtube.com/watch?v=SE-NdrzfFOo this commercial]], which references not only The Lone Ranger but another TV ad of the day for Lark Cigarettes.
** To those who were too young for ''The Lone Ranger'' but old enough to watch a [[UnratedEdition certain incarnation]] of ''The Creator/TexAvery Show'', and are sadly unfamiliar with the origin of the piece, the tune could bring to mind a montage of zany animation.
** And are too old for ''The Creator/TexAvery Show'' but too young for ''TheLoneRanger'' will be thinking of [[YouCantDoThatOnTelevision a different montage of zany animation entirely.]]
* "Radio/TheShadow knows". Yeah, great, what does ''that'' mean, exactly? The full line goes "Who knows what evil lurks in the hearts of men? The Shadow knows!". The Shadow is a psychic and fights crime by implanting the suggestion in a person's head that he's invisible, so he can eavesdrop a lot.
[[/folder]]

[[folder:Theater]]
* Various bits from the works of Creator/WilliamShakespeare have been quoted, parodied, imitated and plagiarized too many times to count. Particularly notable are cases in which Hamlet's "[[DrivenToSuicide To be or not to be]]" soliloquy is confused with the "Alas, poor Yorick" one, leading to an actor reciting the former while holding the prop skull that belongs in the latter. There's a fair amount of BeamMeUpScotty at work, too: "Alas poor Yorick, I knew him" often has a "well" added to the end in pop culture.
** Orsino's opening line of "If music be the food of love, play on," from Theatre/TwelfthNight is often assumed to be quite romantic and/or demonstrative of a love of art. Very few include the rest of the quote: "Give me excess of it; that surfeiting,/The appetite may sicken, and so die."
** A particularly egregious example is the way in which Juliet's speech "Oh Romeo, Romeo, wherefore art thou Romeo?" usually has a spurious comma added after the "thou", completely changing the meaning. "Wherefore" actually stands in the same relationship to "therefore" as "where" does to "there"; it doesn't mean "where", it means "why". Juliet is not wondering where Romeo is as commonly supposed, but is speaking to him and asking the reason for his name. (Sounds weird the first time you hear it, but it becomes cleat what she means: "Why did the man I fell in love with have to be Romeo Montague, probably my father's last choice on earth of son-in-law?")
*** Also, the name of the play being used to mean an ideal romance other than the ludicrously over-emotional and too-fast mess that the play portrays it as.
** ''Romeo And Juliet'' itself is not a Shakespeare original, but based on an even older Italian novella. Few of Shakespeare's plays (possibly none) had original plots.
*** This makes it even funnier to watch the bits in ShakespeareInLove where Will is trying to work out how the story will end.
** 'Now is the winter of our discontent' is often said as a negative rather than the happy occasion it is 'made glorious summer by this sun of York"
*** As Richard is the one who says the line, it is rather bitter/sarcastic
* Gilbert And Sullivan's "I am the very model of a modern major general" has been spoofed in so many cartoons, movies, and what have you, that everyone recognizes it, several people don't realize this until it's referenced in ''VideoGame/MassEffect2''.
* How many people quote lines from Creator/JohannWolfgangVonGoethe's play ''Theatre/{{Faust}}'' and especially the following ''Theatre/FaustII'' (''Faust, der Tragödie Zweiter Teil'') without knowing where it's originally from?
* Similarly, many people have heard this line from Creator/ChristopherMarlowe's ''Theatre/TheTragicalHistoryOfDoctorFaustus'': "Was this the face that launch'd a thousand ships." However, many people today only know it from the ''Series/{{Star Trek|The Original Series}}'' episode "The Squire of Gothos", some snarky comments about metaphors in ''Literature/{{Discworld}}'' novels, and/or ''Film/ShakespeareInLove''.
* Actor Gustaf Gründgens' famous performances as Mephisto, with sinister stark white make-up, black eye shadow and sharply upturned eyebrows, have definitely influenced later despictions of the devil in visual media.
* SpringAwakening is only thought by many people to be a musical set in 1890s Germany, unless they actually look into it at all and find the original Frank Wedekind play on which it is based.
* Look up any Website/YouTube video for "Seasons of Love", and you will see an overwhelming number of comments about how people sang it for choir/graduation/etc. and didn't know it was from {{Rent}}.

* You've heard the ''VideoGame/{{Tetris}}'' theme song, right? Well, turns out it's actually a Russian folk song called "Korobeiniki", and is only really associated with ''Tetris'' outside of Russia. The association is so strong, the otherwise public domain song has become a trademark of ''Tetris'' within the video game industry.
* ''VideoGame/WorldOfWarcraft'' is absolutely the king of this, being both {{Troperrific}} and jam-packed with {{shout out}}s to damn near everything under the sun. From music/bands, novels, films and TV shows, and other video games, from the popular to the extremely obscure, if you name a piece of media, chances are pretty good that ''[=WoW=]'' has referenced it. This naturally leads to a great deal of OlderThanTheyThink, particularly for the younger and more...[[FanDumb culturally]] [[FanBoy unaware]] in the fandom. This even applies to the ''[[WarcraftExpandedUniverse Warcraft franchise]] itself'', since the MMO contains many {{mythology gag}}s which are {{shout out}}s to the older RTS games, and other Blizzard games. Just look at [[http://www.wowwiki.com/In-jokes_and_references this list]] for examples. Beyond the references, gameplay elements themselves are victims to this, since [=WoW=] is the 800 lb gorilla of the MMO genre. {{Fandumb}} often accuses other games of "ripping off" ''[=WoW=]'' features, when those other games had them first.
** Similarly with ''VideoGame/{{Starcraft}}'' when ''VideoGame/DawnOfWar'' came out there were plenty of ''Starcraft'' fans accusing it of ripping off ''Starcraft''.
*** Interesting example in that Dawn of War's [[TabletopGame/{{Warhammer 40000}} source material]] is older than Starcraft, but its gameplay mechanic is not, making this FanDumb half of the time.
*** ...except that the mechanics they share are basic elements of the genre that were invented in ''VideoGame/DuneII'' by Westwood, and the two are as far apart in gameplay as two [=RTSs=] can be.
* ''VideoGame/TheLegendOfZeldaOcarinaOfTime'': Many people didn't know what an ocarina was before this game was released. They were fairly popular in Japan before the game was released, but in 1998, [[TheRedStapler ocarina makers were suddenly inundated with orders for sweet potato (aka transverse) ocarinas]]. No, the little four-hole wooden ones wouldn't do. They had to be the 10-hole ceramic kind. And they had to be blue. Many music stores were sold out and couldn't figure out why.
** Humorously, it's not the first Zelda game that uses a ocarina either. Both ''TheLegendOfZeldaALinkToThePast'' and ''TheLegendOfZeldaLinksAwakening'' featured the instrument, though it was not as central to the plot.
** And it's not even the first Nintendo game to use one. That would be ''VideoGame/{{Mother}}'', but [[NoExportForYou that one has an excuse.]]
* Many Western gamers assume that ''Guitar Freaks'' (or any long-running Japanese rhythm game) ripped off ''GuitarHero''. ''Guitar Freaks'' has been around since 1999; ''GuitarHero'' wasn't released until 2005.
* People unfamiliar with the ''VideoGame/{{Touhou}}'' series will automatically assume that "U.N. Owen was her?" is called "[=McRolled=]" all thanks to a viral video much to the annoyance of fans who hate that name.
** Even worse, someone posted a remix of "U.N. Owen Was Her?" as John Stump's "Death Waltz", causing much confusion between both songs[[note]]The remix is merely really complex, while the actual Death Waltz is impossible to play and entirely unrelated to "U. N. Owen"[[/note]].
* The main character in ''VideoGame/PokemonRedAndBlue'' is named Red. But he's often called Ash by people more familiar with the anime. Similarily, his rival Blue is referred to as "Gary".
** It's less incorrect if the person in question is referring to the main character of ''Yellow'', which [[RecursiveAdaptation incorporates many elements from the first season of the anime]].
* This is pretty common in ''VideoGame/SuperMarioWorld'' ROM hacks and Mario fan games in general since some of the more well known ones use resources from obscure Japanese [=RPGs=] people likely haven't heard of (''VideoGame/RomancingSaGa'', ''VideoGame/LiveALive'' and ''VideoGame/SeikenDensetsu3'' being some examples) and as a result some people tend to associate said resources with the fan game/hack rather than the original SNES one. Such as how many people don't know that things like the Mirage Palace and Dark Castle are from ''Seiken Densetsu 3'' and not ''VideoGame/BrutalMario'', or that the 7 Koopalings boss is a parody of the final boss in Romancing [=SaGa=] 2. This can lead to awkwardness if people assume any resources from these games are plagarised.

[[folder:Western Animation]]
* Many famous pieces of classical music have been hijacked by Disney, ''WesternAnimation/LooneyTunes'' and other (usually older) animated sequences, and are many people's only exposure to such works. Many people still have the urge to sing "Kill the Wa-bbit" along to Creator/RichardWagner's "Music/RideOfTheValkyries", thanks to Elmer Fudd's memorable version in the classic Characters/BugsBunny short ''What's Opera, Doc?'' And the use of a romanticized version of the ''Pilgrims' Chorus'' when Bugs enters on horseback, dressed as Brunnhilde, and fools Elmer/Thor (he used the same entrance, music and disguise with equal success against [[ThoseWackyNazis Hermann Goerring]] in a wartime cartoon).
** ''Series/ThirtyRock'' had an episode where it's revealed Liz's cell phone ringtone is "Ride of the Valkyries", resulting in this exchange:
--->'''Phoebe:''' Oh, you like Wagner.\\
'''Liz:''' No, I like Elmer Fudd.
** ''WesternAnimation/LooneyTunes'' also stole heavily from "The William Tell Overture" by Rossini, to the point where almost every major theme in the piece has been used in some cartoon. For a lot of those, it's via another reference—see below.
*** And Rossini suffers again in ''Rabbit of Seville'', this time with the overture for the Barber of Seville.
** How many people can listen to Franz Liszt's Hungarian Rhapsody no.2 and ''not'' be thinking of a cartoon at the same time?
*** ''Dance of the Reed Flutes'': Are you thinking of Cadbury's Fruit and Nut or ''VideoGame/{{Lemmings}}''?
*** Similar to the above with ''Dance of The Sugar-Plum Fairy'' for ''Tetris'' - although "Korobeiniki" (see further down this page) is even more strongly associated with it.
*** Before ''Disney/{{Fantasia 2000}}'', most people would (and still do) associate "Rhapsody in Blue" as the theme song of United Airlines.
*** The Theme from Peter Gunn was composed for the TV series ''PeterGunn'', in 1958.
*** FelixMendelssohn's "Spring Song" has probably been heard and remembered more from old cartoons than from the concert hall or recordings.
** Likewise, if you've heard of the turn-of-the-century song "Hello, Ma Baby", it was probably from ''One Froggy Evening''.
*** Or perhaps even ''Film/{{Spaceballs}}'', which seems to have used it in reference to ''One Froggy Evening''. It's even the same recording of the song!
** Raymond Scott's [[http://www.youtube.com/watch?v=YfDqR4fqIWE "Powerhouse"]] is inextricably linked to assembly-line montages thanks to ''Looney Tunes''.
*** Or the Creator/CartoonNetwork bumpers from the '90s.
*** It's also widely known as the middle section of ''[[{{Rush}} La Villa Strangiato]]'' and the accordion solo of "[[TheyMightBeGiants Rhythm Section Want Ad]]."
** Can anyone today even hear the English '''title''' of Verdi's ''Coro di zingari'' -- a.k.a. the "Anvil Chorus" -- and ''not'' think of LooneyTunes characters dropping anvils on one another? The actual ''song'' is about gypsies arising at dawn for their day's work, and looking forward to wine and women later on.
** You know the theme song to the old Road Runner cartoons? That's actually the Dance of the Comedians from Smetana's "Bartered Bride". [[http://www.youtube.com/watch?v=Y7uEV7FAua8 See for yourself.]]
** WesternAnimation/{{Wile E Coyote|and the Roadrunner}} comes from NativeAmericanMythology.
** How about ''The Merry Go Round Broke Down'' for the WesternAnimation/LooneyTunes theme song?
** The character Foghorn Leghorn was based on the character Beauregard Claghorn, from Fred Allen's ''Allen's Alley'' radio program.
* "Sing, Sing, Sing", originally by Louis Prima, played most famously by Benny Goodman, is known to a whole generation of eighteen-to-twenty-somethings as "the Chips Ahoy song".
** "Sing, Sing, Sing" seems to be ''the'' stock music used to evoke '30s swing jazz.
*** [[CrowningMusicOfAwesome With damn good reason.]]
** "Poet and Peasant Overture'' is another piece of background music used a lot in Looney Tunes. It was also used in the WesternAnimation/{{Animaniacs}} cartoon "PottyEmergency".
* WoodyWoodpecker's laugh is so universally recognized, that some people even forget where the AnnoyingLaugh to rule them all came from in the first place.
* Some young adults are reminded of ''WesternAnimation/HeyArnold'' when they hear music from ''Carmen'', ''Pagliacci'', or "Ride of the Valkyries" thanks to the episode "What's Opera Arnold"?
** The name of episode itself is a shout out to the well known Bugs Bunny episode "What's Opera Doc?", and it also contains a parody of Elmer's infamous "spear and magic helmet" line.
* The animated Saturday morning show ''TheSmurfs'' used nothing but clips of classical music for mood and theme setting.
* ''WesternAnimation/{{Futurama}}'' has an example in the boy from the pair of Victorian dressed StreetUrchin children who are recurring characters. They are clearly meant to evoke Creator/CharlesDickens, as his crutch is identical to that famously used by ''Literature/AChristmasCarol'''s Tiny Tim, although what the writers seem to have missed was that Tiny Tim was ''not'' one of Dickens' urchin characters. Then again, it's ''WesternAnimation/{{Futurama}}''; it was probably on purpose.
** Lampshaded again in ''WesternAnimation/{{Futurama}}'', as the Fungineers who designed the Moon Landing 'historical' recreation with singing whale hunters as astronauts have certainly gotten their historical facts through popcultural osmosis.
*** Fungineering as a whole seems to be based on a massive foundation of MemeticMutation.
** Not many [[PeripheryDemographic fans outside America (or at least some outside Nixon's generation)]] remember that Spiro Agnew ''was an actual person'', let alone one of [[RichardNixon Nixon's]] Vice Presidents.
** Another one from ''WesternAnimation/{{Futurama}}'' is simply the ''theme song''. Most people associate it with the series, but it's actually just a slightly tweaked version of part of the Maurice Béjart ballet ''Mass for our time''. The original was written back in 1967 by experimental composer Pierre Henry and [[http://www.youtube.com/watch?v=X7bnNkofnd0 is entitled "Psyche Rock"]].
* Speaking of ''Disney/{{Fantasia}}'', there's likely not a soul on Earth who doesn't associate "L'apprenti sorcier" by Paul Dukas with MickeyMouse.
** Or take "Dance of the Hours" from Ponchielli's ballet ''La Gioconda.'' When you hear it, you'll either think of the dancing hippos from ''Fantasia'', or you'll start singing, ''"Hello Muddah, hello Fadduh, here I am at Camp Granada..."'' (Creator/AllanSherman's well-known funny song). Or both.
* The "Me Love You Long Time" from the hooker in ''FullMetalJacket'' have been incorrectly credited to both ''WesternAnimation/FamilyGuy'' and ''WesternAnimation/SouthPark''.
** People of a certain age will probably first think of the [[Music/TwoLiveCrew 2 Live Crew]] song "Me So Horny".
*** Or Music/SirMixALot's "Baby Got Back", which similarly references the line.
* ''WesternAnimation/RenAndStimpy's'' music for that show was made up almost entirely of classical and jazz music.
** Ren & Stimpy closely associate Raymond Scott's "The Toy Trumpet" with the army. The tune has been heard just everywhere, but no one can even place it: [[http://www.youtube.com/watch?v=XOAkl1Id_EE]]
* Many kids today will hear old Hawaiian standards only to think they first came from ''WesternAnimation/SpongebobSquarepants'' or ''WesternAnimation/LiloAndStitch''.
* In the Henry and June segments on ''KaBlam'', kids might think that the ska background music originated from the show, but they're really just instrumental versions of songs by The Toasters.
** Also, the H&J shorts as well as ''ActionLeagueNow'' used various stock/classical pieces often used in ''Spongebob'' or ''WesternAnimation/TheMightyB''.
* As the page image shows, ''Franchise/TeenageMutantNinjaTurtles'' will make sure every teacher talking about the Renaissance will have a joke regarding LeonardoDaVinci, [[NamedAfterSomebodyFamous Michelangelo Buonarotti]], [[http://a1.s6img.com/cdn/0014/p/4577675_13944572_lz.jpg Donato di Niccolò di Betto Bardi,]] [[http://blogs.artinfo.com/artintheair/files/2013/07/teenage-mutant-ninja-painters.jpg and Raphael Sanzio]].;
** ''WesternAnimation/{{Animaniacs}}'' tackles this head-on during [[http://www.youtube.com/watch?v=hKJRywDsthU a segment about Michelangelo]].
--> '''Narrator''' (after [[CaptainErsatz four masked turtles]] hop out of a sewer pipe): I'm afraid popular culture as successfully eradicated the actual identities of the true poets of art. In my opinion, it stinks!...And now for a brief reality check. Michelangelo was a brilliant artist. Not a turtle.
** Speaking of ''Animaniacs'', ''Humoreske'' was a romantic piano piece composed in 1839, but most 90s kids call it the "Slappy Squirrel Theme".
* Due to the penchant most voice actors had for impersonations, many young viewers were able to recognize the voices of famous actors and celebrities long before they had any idea of who they were.
** ''RenAndStimpy'' were modeled after Peter Lorre and [[Film/TheThreeStooges Larry Fine]], respectively.
** You would have a shorter list of characters who WEREN'T some example of this trope on ''WesternAnimation/{{Animaniacs}}'' then the ones who were. To name a few: [[Music/RingoStarr Wakko]], [[RainMan Runt]], [[GoodFellas Goodpigeons]] and [[Film/TheGodfather The Godpigeon]], [[OrsonWelles The Brain]], [[JerryLewis Mr. Director]], ...
* The slow motion walk in ''[[WesternAnimation/MonstersInc Monsters, Inc.]]'' is often misattributed to ''Film/{{Armageddon}}'', instead of ''Film/TheRightStuff''.
* In one episode of ''SouthPark'', Mr. Garrison is brought before a disciplinary committee for his actions from a previous episode. When they review just what he's done for the 3rd grade education, one of them notes he hasn't even taught the kids about Samuel Adams, leading a confused Garrison to ask "Well who cares about a guy who makes beer?!", [[LampshadeHanging referencing the fact]] that most people are probably more familiar with the alcohol brand over the one of the founding fathers of the country.
* What people used to think of when they heard the phrase: "The Snow Queen": "Oh, [[Literature/TheSnowQueen that fairy-tale]] by Creator/HansChristianAndersen." What many (especially the younger generation who never heard of the original) are starting to think of now: ''[[Disney/{{Frozen}} "Let it go, let it go..."]]''
