Quote from Kramer in The Couch
Kramer: All right, put a little sauce on here. Some cheese. Poppie: Not too much! Kramer: And cucumbers! Poppie: Wait a second. What is that? Kramer: It's cucumbers. Poppie: No, no. You can't put cucumbers on a pizza. Kramer: Well, why not? I like cucumbers. Poppie: That's not a pizza. It'll taste terrible. Kramer: But that's the idea, you make your own pie. Poppie: Yes, but we cannot give the people the right to choose any topping they want! Now, on this issue, there can be no debate! Kramer: What gives you the right to tell me how I would make my pie? Poppie: Because it's a pizza! Kramer: It's not a pizza until it comes out of the oven! Poppie: It's a pizza the moment you put your fists in the dough! Kramer: No, it isn't! Poppie: Yes, it is!
