College football fans are probably the most passionate fans out there. And rivalries run deep. So deep, in fact, that fans will often jump at the chance to prove their undying faith in their teams by promising to do some crazy things if they lose. Of course if they win, the tables turn. That's a gentlemanly wager, and it becomes an unbreakable social contract between fans with a simple shake of hands. It's not crazy, it's sports.
