Actually, if Clay was not the mole, doing something so erratic and controversial would be a good idea, since then the chance that you would be the only one to do it would be very great, and it might also be a quiz question, giving you a freebie. Like, maybe he figured no one else would be so dumb to join him, and so therefor, if there was a question on the quiz concerning whether or not people participated, he would get a freebie. I would always try to be the odd one out on this show (when it suited me), just to get freebies.
