Jonathan Roy, son of legendary goalie Patrick Roy, plays his father's position for the Quebec Remparts of the something-or-other league in Canadia. The video above shows the Remparts' brawl against the Chicoutimi Sagueneens (ed. note: the where whats now?). And as you can see from Jonathan's actions at about the 1:25 mark, it takes a real man to sneak away from being restrained in order to beat the crap out of someone who has done nothing to you and won't lift a finger against you.
Bonus points to Roy's teammate for tackling the ref who tries to intercede. You can do that in hockey? Wow.
