Quote from Niles in To Kill a Talking Bird
Niles: Ah, I'm glad you made it. Frasier: You know, Niles, this precious little building of yours isn't as exclusive as you think. Your doorman waved me right through. Niles: Well, that's because he knows you. Frasier: Oh, fan of my show? Niles: No, he lives in your building.
