Quote from Frasier in The Two Mrs. Cranes
Frasier: Oh, hello. You must be Clive. Clive: Yeah, and you are? Frasier: Dr. Frasier Crane. Clive: Oh, Niles's brother. Frasier: Yes. You met Niles? Clive: Just now. Though I used to know his wife quite well. Frasier: Really, you know his wife? Clive: She's one of a kind, that one. Frasier: Isn't she? [laughs] Clive: Certainly can light up a room. Frasier: Oh, yes, usually by leaving it.
