I made a bet with my friend who is a Saints fan when we were drunk. I actually have the envelope with the "contract" written out on it in my office desk drawer with $40 sealed inside. It reads:
Week to week we are going to bet to determine whether our respective teams will win or lose against the spread on bodog.com. In the end whoever has the best record of correct predictions for their teams regular season wins a total of $40.00. The loser has to have a picture taken in a bathtub full of potatoes with the winner's team jersey on.
We were pretty drunk.
