Diane: Oh, my.
Sam: What's wrong?
Diane: Oh, don't you see? Frasier's in love.
Sam: He's what?
Diane: Oh, come on, Sam. You're forgetting I was once romantically involved with Frasier. I know when he's enamored of someone. Didn't you see his nostrils flare? And everyone knows that hate is not the opposite of love. Indifference is.
Sam: Well, whatever you say. I really don't care.
Diane: Touche, Sam. Let's be honest. Quite often you've expressed feelings of antagonism toward me, and we both know how much you love me.
Sam: I- I do not love you, Diane, and I have the nostrils to prove it.
