You're trapped in a (temporarily) out of order elevator - who would you like to be trapped with?
God. I assume that he has the best chance of getting us untrapped. Talented man he is. But if it is like, super-trapped, then someone who makes good conversation, and someone very smart - probably an author - Ian McEwan, Ray Kurzweil, Murakami, Philip Pullman, Lisa Randall?
