Nash: Well, Martin Hansen. It is Martin, isn't it? Hansen: Why yes, John, it is. Nash: I assume you've gotten quite used to miscalculation. I read your pre-prints. Both of 'em. One on Nazi scientists and the other one on, uh... non-linear equations, and I'm extremely confident that there's not one seminal or innovative idea in either one of them... Enjoy your punch.
