Frasier Crane:
[about his dog, who Sam now owns] So, Sam, listen, fill me in. I'm hungry for news about little Pavlov.

Sam Malone:
[a slight pause] Pavlov? Oh, you must mean little Diane.

Frasier Crane:
I beg your pardon?

Sam Malone:
Yeah, I renamed the puppy "Diane". I figured you wouldn't mind. I mean it's my puppy now. Yeah, oh boy, I tell you, it's so wonderful. I come home, she gives me a little trouble, I swat her on the rear end, I say, "Shut up, Diane", and she does. It's heaven.

Frasier Crane:
Sam, I have to be honest with you. Changing the dog's name hurts me a little. Don't you think two "Diane"'s will be a little confusing?

Sam Malone:
Well, maybe you're right. I hadn't thought of that. Well, we'll just have to call your girlfriend "Pavlov".
