One time in jazz band at 0:dark:30:
The band was rehearsing a song called “Makin’ Whoopie” when a trumpet player started making farting noises.
Katie: Are you makin’ whoopie?
Trumpet player: If your definition of makin’ whoopie involves farting, there is something wrong with you.
Katie: Well that is the sound a whoopie cushion makes. I thought this song was about farting.
[Insert more band laughter here]
Trumpet player: Well you see, when a mommy and a daddy love each other…
[More and more and more band laughter which included director too.]
