For your enjoyment, here is some great dialogue from the movie Airplane. Why am I providing this? Because it is funny and because I wanted to.

Roger Murdock: We have clearance, Clarence.
Capt. Clarence Oveur: Roger, Roger. What's our vector, Victor?
Tower: Tower Radio, clearance, over.
Oveur: That's 'Clarence Oveur', over.
Tower: Roger.
Roger Murdock: Huh?
Tower: Roger, over.
Roger Murdock: What?
Capt. Oveur: Huh?

Many thanks to Kaelin for providing this.
