Quote from Carla in Rat Girl
Woody: That'll be $7.50, Dr. Crane. Frasier: Oh, yes, of course. Oh, gee, l- I've only got big bills. Well, perhaps Lilith has some change. Oh, dear God. Sam: What? What is it? Frasier: Lilith is carrying a dead rat in her purse. Carla: Oh. Frasier: Why would she be carrying a dead rat in her purse? Carla: Just a wild guess. A snack?
