Quote from Niles in Fool Me Once, Shame on You. Fool Me Twice...
Niles: Do you believe that woman? That's the second time that's happened to me this week. I have half a mind to say something. Frasier: Well, then why don't you? Niles: Oh, you know. Something happens to me when I talk to a beautiful woman. From the moment they begin staring into my eyes, my knees turn to jelly. Frasier: Still, Niles, we both know the only way to break people off their bad habits is by confronting them. [The woman walks up to the counter and stands next to Niles] Niles: Oh, that's true. Frasier: So? [gestures toward the woman] Waiter: Who's next here? Woman: I am! I'll have a cafe. Niles: Oh, oh, oh, oh! No, you're not! You weren't next here, I am! I suppose people like you who glide through life wrapped in a cozy little cocoon of narcissism never notice such things. But you'd do well to learn this lesson, sister! There's still such a thing as good manners in this world, and that's why I would like to insist that you let me buy you your coffee and also please try the poppy seed muffins. Woman: Thank you. Niles: You're welcome. [Niles places money on the counter and staggers away] Frasier: You were kind of brutal, weren't you? Niles: All I remember is I was next, and then the sound of blood thundering through my ears.
