[[caption-width-right:350:Yep, the song's now [[{{Earworm}} stuck in your head]]. You're welcome.]]

Officially, it's the "Infernal Galop" from from Act II, Scene 2 of Jacques Offenbach's 1858 operetta ''Orpheus in the Underworld.''

To the rest of the world, it's simply "the cancan song." And it's usually (although not always) a cue for high-kicking ChorusGirls to hit the stage. To that end, it's a quintessential part of the PublicDomainSoundtrack and StandardSnippet tropes.

(And if the song's already running through your head as you read this? Yeah, it's a major {{Earworm}} as well...)

Because of its high-energy, feel-good nature, its use as a trope falls under one of the following conditions:

* '''Type A:''' Accompanying a performance of the cancan dance itself.
* '''Type B:''' To underscore a comedic/slapstick action sequence.

Remember: not all performances of the cancan (dance) are set to the Cancan Song, and not all appearances of the song signal a performance of the dance.

[[folder:Advertising]]
* The Shop Rite supermarket chain's long-running annual (and more recently, ''semi-''annual) [[http://www.youtube.com/watch?v=VLjtiDWHKuI Can Can sale of canned goods]]. Type A, but with custom lyrics ''("Now, Shop Rite does the cancan/Selling lots of brands of/Everything in/Cans cans!")''
* Also Type A: Scottish brewer Irn-Bru set a world record in 2009 by getting 10,000 people to kick up their heels as part of their [[http://www.youtube.com/watch?v=3j67PLblVts "Can Clan" campaign]]. Real cancan dancers were recruited to help out.
[[/folder]]

[[folder:Anime]]
* ''Manga/FairyTail'': Type B. The song typically plays whenever there's a BarBrawl.
* In ''Anime/KillLaKill'', this is one of the {{standard snippet}}s played by MusicalAssassin Nonon in her fight against Ryuko.
** It also plays in episode 16 while Senketsu narrates the world's shortest RecapEpisode in under a minute and a half.
[[/folder]]

[[folder:Film]]
* Film/FrenchCancan: Type A, and rightly so.
* Averted in both the 1952 and [[Film/MoulinRouge 2001]] ''Moulin Rouge'' films, although Music/FatboySlim's thumping version from the latter has become an alternate soundtrack for many dance troupes, and the pitch scene is performed to the same music.
* Also averted in the Music/FrankSinatra[=/=]Creator/ShirleyMacLaine film of Music/ColePorter's ''Can-Can.''
* Film/{{Stardust}} has a Type B usage of the song: the (literally) closeted Captain Shakespeare minces about in his wardrobe while a sword battle rages outside his cabin.
* Film/LooneyTunesBackInAction: Averted in the live-action saloon scenes, but played straight as a Type A when Elmer Fudd is chasing Bugs and Daffy through the Louvre and they wind up in one of Toulouse-Lautrec's paintings.
* Film/MidnightInParis: Type A.
* ''PetersFriends'' begins with six college friends performing the Can-Can based "The Underground Song" at a school function before graduation. At the end of the movie, [[{{Bookends}} they sing the song together at a reunion]], cementing their TrueCompanions status.
[[/folder]]

[[folder:Live Action TV]]
* Series/TheBennyHillShow had at least two Type A occurences -- but in these cases, they were "normal" women (e.g. policewomen, hospital nurses) inspired to kick it up when the song commenced. (Ironically, the one time the show included REAL cancan dancers, they performed to Khachaturian's "Sabre Dance.")

[[folder:Music]]
* Long-running English band Bad Manners feature a ska-flavored take on Music/TheCancanSong as a part of their set. That's the good news. The ''bad'' news is that their (male, bald) singer will often ''perform'' the cancan. In drag.
* KrautRock[=/=]SpaceRock band Music/{{Can}} snuck a version onto their eponymous 1979 album (as part of their "Ethnological Forgery" series). Doubles as a StealthPun on their name.
* This [[http://www.youtube.com/watch?v=HXcieUVLz-I chiptune version]] was built out of sounds and samples from VideoGame/SuperMarioBros1 And it is ''hilarious.''
* Acapella group Straight No Chaser's [[https://www.youtube.com/watch?v=7E-47VmFopE "Christmas Can-Can"]].
[[/folder]]

[[folder: Theme Parks]]
* Any Wild West-themed park with saloon girls will likely fall into Type A territory.
* Averted at [[Ride/DisneyThemeParks DisneyLand]]: their recent revival of the Golden Horseshoe Saloon show used Music/ColePorter's ''Can-Can'' song.
* The GreatDickensChristmasFair: Type A, to accompany performances by [[http://www.cancanbijou.com Le Cancan Bijou]].
[[/folder]]

[[folder: Video Games]]
* Too many occurences to mention. See the "Video Games" folder under PublicDomainSoundtrack.
[[/folder]]

[[folder:Web Animation]]

* Yu-Gi-Oh: The Abridged Series has a version sung by Tristan and Joey.
-> "We just kicked a little can can, tell me who's the man, man!"
[[/folder]]

[[folder:Western Animation]]
* Disney/TheLittleMermaid: Type B (the scene where the Royal Chef is chasing Sebastian the Crab, and [[HilarityEnsues comic mayhem ensues]]).
[[/folder]]

[[folder:Real Life]]
* The number of amateur and professional dance troupes worldwide who perform the cancan to the Infernal Galop is literally in the hundreds, if not thousands.
