Diane: Sam, I have to ask you a question. And promise me you won't make a joke out of it. OK? Promise.
Sam: Yeah, I promise. What's up?
Diane: Do you think I'm crazy?
Sam: Yes.
Diane: Ha ha! Now we've gotten the joke out of the way, will you help me? I know this is a strange question, but it's important. Do you think I'm crazy?
Sam: Yes.
Diane: I should have known better. You're incapable of a rational conversation. Everything has to be some flip remark.
Sam: Well, wait a minute. Do you mean are you crazy, like seriously unbalanced, like losing your grasp on reality?
Diane: Yes.
Sam: Oh, well, then yes.
