Sam: Uh, Frasier? There's a theory going around the bar that you're ticked off with Dr. Sternin because you're in love with her. What do you think?
Frasier: Well, that sounds like someone who doesn't know shortcake from Shinola.
Sam: Hey, good guess, good guess. Diane.
Frasier: Oh, well, hmm. That's nothing but mere cocktail-party psychology. Believe it or not, Sam, it's actually possible to have hostile feelings toward 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.
