Frasier: [to waiter] Oh, excuse me, may I have non-fat cappuccino, please? [to Niles] Well, what am I to deduce, that you've recently gotten lucky?
Niles: Yes. And here's the kicker: she lives in your building. Five floors down, Allison Landis.
Frasier: Well, you little sneak. I don't even know the woman. How did you two meet?
Niles: Well, we were just chatting on the elevator. I walked her to her car, where it turned out she'd locked her keys inside. My resourcefulness saved the day.
Frasier: What did you do, fish them out with a coat hanger?
Niles: No, I called the auto club. Where would I find a coat hanger?
