Frasier: Dad, what have I told you about bivouacking in the entrance way?
Martin: I'm sorry.
Frasier: Well, how was your hunting trip?
Martin: Oh, came home empty-handed.
Frasier: Oh, dear. I guess that means for the next several weeks we'll hear you grouse about the grouse and carp about the carp.
Niles: You've been working on that, haven't you?
Frasier: Well, there was traffic.
