There was a legitimate fight that broke out one time in Milwaukee at a Brewers game. They don't really have a mascot, just some guy who slides down a big slide every time a home run is hit (best job ever, right?) but they have these four sausages that race, and people actually bet money on them. So the one sausage trips the other one, and they went fucking at it. At first everyone thought it was staged, but it wasn't.
oh wait. I looked it up. It was a baseball player who hit one of the sausages with a bat which knocked the other ones over, and the sausages helped each other up. The MLB fined and suspended the guy, and the mascots finished the race. Mascots stick together.
