Quote from Frasier in Don Juan in Hell (Part 2)
Frasier: Oh, dear God. Not her! Diane: That person's not wearing shoes. Lilith: That's Nanette. His first wife. Diane: She's going to get hookworm. Lilith: He's obviously dredging up past relationships in order to identify a pattern. Diane: Why, Frasier Crane, you were a hippie. Frasier: I was 20. That was during my impulsive, rebellious phase.
