Montreal and Boston fans fight in the stands.

Via Larry Brown Sports:

Perhaps Montreal’s 1-0 loss to the Bruins on Monday night would help explain why a pretty big fan fight broke out in the middle of the game. The intriguing part about it is it almost looks like no Boston fans are involved based on attire, although said it was a Bruins-Habs thing. Check out this Canadiens fans fight video:

Really bizarre.
