Quote from George in The Scofflaw
Jerry: So he's been lying to me for two months?! George: That's right. Jerry: What kind of person is this? There's only one other person who might be able to do something like this, and that's you. George: Well... Jerry: I don't even think you could do it. George: Oh, I could do it. Jerry: Yeah, I guess you could. George: [snorts] Come on.
