I think Superman probably has a very good sense of humor.

George

I never heard him say anything really funny.

Jerry

But it's common sense. He's got super strength, super speed. I'm sure he's got super humor.

George

You would think that, but either you're born with a sense of humor, or you're not. It's not going to change even if you go from the red sun of Krypton all the way to the yellow sun of the Earth.

Jerry

Why? Why would that one area of his mind not be affected by the yellow sun of Earth?
