Sausage Beater

In one of the strangest stories I've ever read, Randall Simon of the Pirates was charged with misdemeanor battery for hitting a Milwaukee Brewers mascot dressed like a sausage with a bat! What the hell was this guy thinking? He probably thought he was doing something funny, but this has to go down as one of the most stupid acts ever by a professional athlete. What are some of your most memorable "stupid acts" by athletes?
