Poor Kyle Hay. The guy just wanted to celebrate his birthday at the Bruins/Leafs playoff game and support his team.

Too bad for him that he is a Toronto Maple Leafs fan because that got him a nice sucker punch right after the Leafs won game 2 at the garden. Now, before you go "speculate" that he had it coming, his friend says he wasn't chirping or talking to anyone after the game was over, just walking, and the sucker punch came from one Bruins fan who just decided to act out and knock him unconscious as you can see here in the video.

Maybe the guy was just imitating what he sees on the ice from the "Big Bad Bruins". File this one under "Not shocking".
