Frasier: Roz, why is that light still on? Is that Beth who I was talking to?
Roz: No.
Frasier: Yes, it is.
Roz: No, it isn't.
Frasier: I'm sure it is.
Roz: It is not.
Frasier: Have you been talking to Beth?
Roz: Of course not. What do you think, I'm giving advice to your callers? Oh, Frasier, you are so paranoid. The world is full of enemies. Everybody's plotting against you. There's a man in a dark trench coat right behind you.
Frasier: Ho ho, very droll.
John Giroux: Dr. Crane? [Frasier jumps] I'm John Giroux.
