[Diane is on the telephone talking to Sam, while Frasier is very noisily building a fire in the fireplace in the background]
Diane Chambers: Carla has a means of dealing with anger that's very effective. She vents it constantly in small doses to prevent build-up that might erupt in violence. It's a technique that many hot-tempered, uneducated people evolve instinctively, and though it's rather primitive, it is nearly as effective as more sophisticated techniques cultivated and employed by better educated people with gentler tempers...
[abruptly stops her telephone conversation]
Diane Chambers: [immediately shouts madly to Frasier] Stop it, damnit!
Diane Chambers: Sam, I'm sorry. What were we... What was I saying?
Sam Malone: You don't know either? We've got to have a rule around here, when you speak, at least one of us has got to be listening.
[Carla offers to close up the bar since Sam has a date]
Sam Malone: Oh, thank you Carla. I thank you and Debbie thanks you.
Carla Tortelli: I think you're going out with Janet tonight, bean brain.
Sam Malone: Oh, well then, Janet really thanks you.
Sam Malone: [about Drusilla Dimeglio, who is currently in the pool room] I can't believe that's the same woman whose head you were about to shave.
Carla Tortelli: Yeah, yeah, I almost went through with it too. I mean, I came that close, and I could have done it easy, Sammy. I mean, she's not as young as she used to be. But, uh, I stopped. God was testing me Sam, and I passed.
Drusilla Dimeglio: [walks out from the pool room and speaks to Sam] Oh, hello there.
Drusilla Dimeglio: Come on Carla, it's your turn.
Carla Tortelli: OK, I'll be right with you.
[Drusilla turns around and heads back to the pool room. We see that the whole left side of her head is in tact, but the whole right side is shaved of all her hair]
Carla Tortelli: I didn't say I got an 'A' Sammy, I just said I passed.
