Quote from Frasier in Cranes Unplugged
Frederick: Why don't you just talk about it with Uncle Niles? [exits] Frasier: Niles? Well, uh, yes, if that's what you'd like. We'll discuss it together. Niles: "If the engine whistles, let it whistle till it is hoarse for its pain!" Frasier: Oh, shut up, Niles.
