Quote from Niles in Cheerful Goodbyes
Frasier: Listen, I'm sorry that I ruined your evening. Niles: Oh, actually, I ended up rather enjoying myself. Frasier: Really? I can't tell you how happy I am to hear that. I knew that once you met these people you'd learn to love them as I do. Niles: Actually, I've rethought a lot of things. I'm going to give you a much deserved introduction at that conference tomorrow. Frasier: Are you certain? Niles: Oh, you won't be able to stop me.
