Apparently the members of the NYPD and the FDNY hockey teams take their rivalry extremely seriously.

Dennis loves showing off highlights of great hockey plays or fights and this is one for the ages. Check out the video above of a huge brawl that broke out on the ice between the NYPD and FDNY during their matchup yesterday (4/6). The only 2 players that didn't get involved in the brawl were the 2 participating goaltenders.

Thank goodness it was a charity game. We'd hate to see what it'd be like if it was a real game that counted!
