Quote from Lilith in The Cranemakers
Frasier: Sam, if this story is meant to discourage us, it's going to fall on deaf ears. I've already burned our last bridge. I'm proud to announce that the Doctor has given up his practice. Norm: Oh, come on. Sam: You did what? Frasier: Yes. We put our house on the market, I helped Lilith compose her letter of resignation to Boston General, and I just canceled my paranoia workshop. So all we need to do now is buy a stout ax and a plot of land in the wilderness. Lilith: And I'll stand by your side and bear your young and cook your meals. Carla: Try not to get them mixed up. Sam: Ah wait, whoa, hold it. Listen, have either of you even lived outside of the city? Lilith: Well, I admit we are urbanites, but we've always enjoyed the country whenever we've flown over it.
