Niles: Well, that's a bit harsh.
Frasier: Oh, please. This is a woman who believes the Spanish Inquisition was just tough love for heretics.

Frasier: I have someone here with me today, someone you haven't seen for quite a while. There's something she'd like to tell you, something she's wanted to tell you for a very, very long time. Mrs. Mulhern?
Mrs. Mulhern: You little whore!
Nora: Mother!
Mrs. Mulhern: So, you thought you could get away from me, did you? Thought you could leave me to rot in that dump without barely enough cash for a bottle of Mateus. You'll pay for that, missy!
Roz: I was wrong, Frasier! Your way is better!

Frasier: Ah, Dr. Nora.
Nora: Such a frosty tone. Is something the matter?
Frasier: I have just one question—
Roz: What kind of vicious, judgmental, name-calling, machete-mouthed bitch are you?
Frasier: I was going for the less feisty version.
