Hockey Fight!

I am never a fan of hockey. Firstly, I can't skate. Usually, you are only interested in the game when you participated in it before. Secondly, I don't really understand the rules of the game.

However, what's really interest me is the fight you can get out from there. Lolx... The game can be going on smoothly and out of a sudden, you'll find 2 players fighting. In the end? A group fight! Wuahahahaha....

And what's more interesting is that the referees there don't even really dare to stop the fight, afraid that they will get beaten up for no reason. By the way, will the players get send off from the game if they fight during the game? If so, what happen when players from both teams get into a fight? Do both teams get send off too? Hmmm........

Oh one more thing, why don't they use their hockey stick? Or just bump their head into the other party's face? Won't that be easier?
