Martin: In my day, when two people broke up you were mad, you were angry, you hated each other. Whatever happened to the sanctity of divorce?
Frasier: Dad, you never liked Lilith.
Martin: She's weird.
Frasier: She is not weird.
Martin: Oh, she's weird.
Frasier: Well, maybe she's a little strange.
Martin: No, Maris is a little strange. Lilith is weird.
Niles: Gee whiz, Dad, I had no idea you preferred my wife to Frasier's.
