Quote from Daphne in Goodnight, Seattle
Daphne: I've been a bit nervous myself lately, ever since me brothers showed up. Niles: Really? Why? Daphne: Well, you know, the way they keep patting my stomach and saying, "He's a Moon all right!" Niles: Oh, my God, yes. Daphne: And every time they say that, all I can think is, what if he's not? What if he's like you and Frasier?
