Quote from George in The Wife
George: Could it be because you don't want him to know that you have a friend who pees in the shower, is that it?! Elaine: No, that's not it! George: Oh, I think it is! I think that's exactly what it is! Elaine: Why couldn't you just wait? George: I was there! I saw a drain! Elaine: Since when is a drain a toilet?! George: It's all pipes! What's the difference?! Elaine: Different pipes go to different places! You're gonna mix 'em up! George: I'll call a plumber right now!
