Roz: Niles! Every time I give you my chair, you wipe it off first. It's just insulting.
Niles: For your information, I was reaching for my cell phone.
Roz: Oh. I'm sorry, Niles. I stepped out of line. See you later, Frasier. [Roz leaves]
Frasier: Bye bye, Roz.
Waiter: [answering the phone] Café Nervosa.
Niles: [on the phone] Yes, this is Dr. Crane at Table Seven. Could you send someone over to dust off my chair?
Frasier: Oh, for God's sake! I'll do it!

Frasier: A martini, then?
Caitlin: I cut out alcohol last year, along with processed sugar, dairy products and meat. Oh, I hope I'm not screwing up your menu. What are you serving?
Frasier: Well, so far, parsley and curvy orange slices.

Niles: You know what, I think I'm putting you on the spot here. Let's just leave it at congratulations on your new "relationship".
Frasier: What are you implying?
Niles: Oh, I think we both know what kind of "relationship" we're talking about.
Frasier: Would you stop saying the word "relationship" that way? "Relationship".
Niles: I'm not condemning you for your little "fling".
Frasier: Oh, for God's sake.
Niles: Just don't try to pass it off as something deeper than it is. The only thing you two have in common is the faint impression of the word "Sealy" on your backsides.
