Dick: All right, that's it. I may be a whale of a friend, but that doesn't entitle you to stick to me like a pathetic barnacle. I don't care about the problems you're having with your wife, your existential crises, or your inexplicable desire to befriend me. Zap me to oblivion if you want, but so help me, I will never sing another jazz standard with you!
Big Giant Head: Dick, stop!
Dick: No, you stop! Why are you following me? Why are you so fascinated by me? Why do you have to get so close?
Big Giant Head: How dare you talk to me like that?
Dick: Why, because you're the Big Giant Head?
Big Giant Head: No! Because I am... your father.
