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?

[laughing band]

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.]
