Daphne: It's a pretty lady holding some mail. Oh, you didn't pull that trick again, did you?
Frasier: I have no idea what you're talking about. Step aside! Don't want her to slip it under the door! [opening the door] Hello.
Caroline: Hi. Sorry to disturb you. Some of your mail got mixed in with mine.
Frasier: Oh, dear. How did that happen?
Caroline: I don't know. Some of it just seemed to be jammed in there.
Frasier: Uh, huh. Really, well, we must make allowances for our mailman. He's a veteran.
