Niles: "Liar! Liar! Daphne never said that."

Frasier: Well, she said it with body language.
Niles: I happen to be fluent in that language and she said nothing of the kind!

Niles: How dare you try to steal my group.
Frasier: I don't need your group! I've got a group of my own, half a million strong.

Niles: Is he standing directly behind me?
Dr. Schachter: Yes, now trust your brother.
Niles: ... I'd feel better if he were wearing rubber soles.

Frasier: ... You should know he catches like a girl.

Niles: Well, you were closer!
Frasier: It was your turn!
Niles: "It was my turn"!

Frasier: Niles, you are not scaring me. And the thumb goes on the outside, Niles! On the outside!

Frasier: In the meantime, listeners, I've enjoyed our time today. Tune in again tomorrow when we'll be talking
with...
Bulldog: [into microphone] Blah, blah, Frasier Crane Show, happy health, goodbye!

Bulldog: Yo, Jill. You a football fan?
Jill: "Not really."
Bulldog: Then beat it!
