Praiswater: Yeah, I'll buy that. Now we go search the boat.
Lucky: Suppose I resented that?
Praiswater: Fine. So you resent and I search. And you pray I don't find him and I pray I do.
Lucky: Mr. Praiswater, you don't have enough brains to grease a griddle.
Praiswater: No, I can't figure you. You knew he was on the boat. You did stick your neck out.
Lucky: Oh, I just couldn't see turning a man over to his executioner.
Praiswater: Why, you an intellectual?
