History Main / SpontaneousChoreography

* In the original ''Film/StepUp'' Tyler and Nora go to a party and Nora's entire class breaks into SpontaneousChoreography.

** And again in "[[Recap/TheSimpsonsS8E5BartAfterDark Bart After Dark]]" with those who are gathered to tear down the burlesque house and people sing 'We Put the Spring in Sprinfield' ... except Marge who was out renting the bulldozer. She asks if they can sing it again but Ned Flanders tells her it really was one of those spur-of-the-moment type things.

* A gradual build-up in the final scene of ''Sunshine on Leith'', a JukeboxMusical based on the works of Music/TheProclaimers. At first, it just looks like a crowd has gathered around Davy and Yvonne as they start singing "I'm Gonna Be (500 Miles)" on Princes Street. Then on the first chorus, two groups of dancers, one male and one female, pull the bewildered couple into a routine. And by the end, it looks as if ''everyone'' has joined in, even the living statue on the corner!

* The ''Series/BuffyTheVampireSlayer'' episode "Once More with Feeling". [[AWizardDidIt A Demon Did It.]]

* ''WesternAnimation/PhineasAndFerb'' do it at least OncePerEpisode. Taken UpToEleven in [[ExactlyWhatItSaysOnTheTin Rollercoaster: The Musical]], which features this in just about every other scene, and is naturally {{lampshade|Hanging}}d.

* In ''Manga/MairimashitaIrumaKun'' (which is otherwise ''not'' a musical), whenever [[GenkiGirl Clara]] is reunited with her siblings and mother, the Valac family breaks out into choreographed songs. They're the ''only'' characters who do this, and other demons [[LampshadeHanging point out how weird it is]]. But the Valacs are all {{Cloudcuckoolander}}s so it makes sense ''for them'' to behave in such a strange manner. They also use their [[ThePowerOfCreation power to create objects]] to make props for their song and dance routines.

* The above quote is from ''Film/NotAnotherTeenMovie'', which parodies HighSchool movies like ''Film/ShesAllThat'' where all the kids know how to dance really well at prom.

* In ''WebAnimation/{{RWBY}}'' episode "Dance Dance Infiltration", Jaune leads team JNPR into one of these. ''WebAnimation/RWBYChibi'' episode 23 jokes about that scene with the revelation that Red forced the team to drill for the number.

* ''WesternAnimation/FamilyGuy'' does this a lot, particularly the numbers "Shipoopi" (taken directly from ''Theatre/TheMusicMan'', and just as bizarre there), "A Bag of Weed" (a parody of "Me Old Bamboo" from ''Film/ChittyChittyBangBang''), and "Mr. Booze".

* [[http://rhapsodies.wpmorse.com/comic/just-one-musical-number/ One holds up traffic in downtown Homestead]] for at [[NoodleIncident least three hours]] in ''{{Rhapsodies}}''.

** Though as noted by TheNostalgiaChick, it comes off as more of a tacked-on HandWave than a legitimate explanation. The entire student body (or at least all those attending the prom) being taught a complicated dance for that one moment just raises even more questions than it answers.

* ''WesternAnimation/FamilyGuy'' does this a lot particularly the numbers "Shipoopi" (taken directly from ''Theatre/TheMusicMan'', and just as bizarre there), "A Bag of Weed" ("Me Old Bamboo" from ''Film/ChittyChittyBangBang''), and "Mr. Booze".

* A few songs in ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' feature this, like "At the Gala" from "The Best Night Ever" and "Smile, Smile, Smile" from "A Friend in Deed".
** Lampshaded by Rainbow, who finds musicals unrealistic. Then Rarity breaks into song, followed by the other four.

* ''Film/Grease'' pretty much runs on this

** Some fanworks have run with the idea that this is actually a documented natural phenomenon in Equestria, which makes at least as much sense as [[PaintingTheFrostOnWindows a manually operated day-night cycle and seasons that have to be changed by hand.]]
