Quote from Jerry in The Couch
Kramer: Are you sure? Jerry: Well, what is it then?! My new sofa! Poppie peed on my new sofa! Kramer: I'm sure it'll come out. Jerry: I don't care if it comes out. I can't sit on that anymore! Kramer: Ah, you're making too much of it. Jerry: Yeah, you're right. It's just a natural human function. Happens to be on my sofa, instead of in the toilet, where it would normally be. Kramer: Right.
