Context: Monty was explaining to symphonic band how to swing 8th notes.

Monty: "If it's on a down-beat, you say DU. Everybody say DU.
Everybody: "DU"
Monty: "That's disgusting, why would you all say that. Now, if it's on the up-beat you say BA. Everybody say BA."
Everybody: "BA"
Monty: "You are all sheep."
