Quote from Frasier in Travels with Martin
Martin: You know Frasier, I just can't help it. When we're alone together I just don't know what the hell to say. I'm sure you figured out that's why I asked Daphne to come along. Frasier: Well, I had my suspicions but I hoped that wasn't the case. Martin: Oh, knock it off. That's why you asked Niles to come along, too. Frasier: Well, that's why I asked him, but that's not why he came.
