VIDEO: Fans Brawl at Blues-Bruins Games

There's an unspoken rule at any concert or sporting event.... no matter what, you DO NOT throw beer at someone. It's a total dick move... and also, why would you waste a beer that you just paid $13 for!? Well, a brawl broke out last night at the Bruins-Blues game after some idiot thought it would be funny to throw a beer.
