It's the first time Norm is shown entering the bar without saying hi to everyone and everyone yelling "Norm!" This was due to the fact that Norm was deep in conversation with Cliff as they entered.
Lilith: I suggest that your behavior indicates an unacceptable level of sexual frustration. You strike me as a man who needs professional help. Or a girlfriend.
Frasier: And you strike me as a woman who could use a good cuffing.
Frasier: Believe it or not, Sam. It's actually possible to have hostile feelings towards someone without being in love with them.
Sam: You mean I can actually hate Diane without having it mean anything more than I hate her.
Frasier: Feel free.
Frasier: Dr. Foster had to cancel. Dr. Sternin is going to take his place.
Diane: Lilith Sternin?

Carla: Can't handle debating a woman, eh?
Frasier: A woman, yes. An ice cube in heels, no.
(Lilith enters the bar.)
Cliff: Uh, oh. Frost warning!
(Lilith lets her hair down.)
Frasier: You know what? I'm going to kiss you. I'm going to kiss you long and I'm going to kiss you hard. I'm going to kiss you 'til...
(Lilith grabs him and kisses him passionately!)
Frasier: Yes, like that...!

Lilith: I'd like to thank you, Diane, for your Pygmalion-like transformation.
Pygmalion (1912) is a play by George Bernard Shaw that also served as the basis for the musical My Fair Lady. In the story an English speech professor teaches a lower class Cockney flower girl to speak in a refined manner which allows her to pass as a member of the upper class.
