Dancing on a Bus/Playing With

Basic Trope: A Crowd Song that takes place on a bus or train, usually in a Bollywood film.

Played Straight: Everyone on the bus starts singing and someone gets up to dance.
Exaggerated: All the others start dancing and playing musical instruments, too.
Inverted: The Crowd Song in question takes place at the bus stop, not actually on the bus.
Justified:
Subverted: The number begins at the bus stop.
Double Subverted: But continues on the bus.
Deconstructed:
Reconstructed:
Parodied:
- The song in question is "The Wheels on the Bus," "99 Bottles of Beer," or some other such car song.
- The number takes place on a school bus, sung by elementary school or Junior High aged kids. (Bonus Points if the song is a really sappy Bollywood-like song one wouldn't expect to hear from kids.)
- On the subway, someone takes a swing around one of the support poles.
- Even the bus driver gets into it...but who's driving the bus?
- In a deconstructive parody of the above, the bus driver's involvement causes the bus to crash.
Lampshaded: "No Bollywood musical numbers on the bus!"
Averted: Everyone sits quietly on the bus.
Enforced: We need a musical number in here...
Invoked: Someone starts singing in a typical show tune fashion.
Defied: The crowd believes that singing is OK, but dancing would be unsafe, so they all stay in their seats.
Discussed:
Conversed: "Even the bus driver is part of this number...how have they not crashed yet?"
