Margaret: Is it absolutely necessary to make bad jokes while you're operating?
Trapper: Absolutely.

Trapper [to Margaret]: Oh shut up Major.

Frank [about Trapper]: Egotistical, smart-alec. And he didn't even study medicine in his own state.
Margaret: You have to admit he has a certain 'je ne sais quois' about him.

Margaret: I don't think it's asking too much for officers to be military at breakfast.
Trapper: I can't throw-up and salute at the same time.

Margaret: Oh, Frank! You're so above average!
