Quote from Niles in The Unnatural
Frederick: So, when are we going to the game? Frasier: Uh, in a bit. First we have to have a little conversation, the two of us. Uncle Niles, do you think you could give us a moment alone? Niles: Oh, of course. I'll freshen up for the game. [to Freddie] You can fool them, but you can't fool me. I'm on to you, little man.
