The company musical Mike and Sulley in Monsters, Inc. claim to be rehearsing for when surprised in the middle of a heated discussion about baby Boo making her way into the Monster factory - "so help me - so help meeee... And cut!" A funny scene in itself, but even better are the scenes from the company musical shown at the end of the movie, after the credits and the fake outtakes. The musical pretty much sums up the whole movie as a parody in songs - with tons of clichés. Hilarious, and a splendid reason to stay in your seat until after the credits.
