What we've got here is an all-out brawl interrupted by a hockey game. At a Feb. 20 SPHL game, a fistfight erupted between two rival players. Four players skated over to break it up -- then THEY promptly all got into a fight.
After that, it sort of spiraled downward (or upward) into a sort of bench-clearing brawl along the general lines of "the more the merrier." (Video)
