Patrice Bergeron scores for Bruins, thanks to a ridiculously lucky bounce (Video)

What has to happen for two teams to combine for five goals in a period?

A little luck, for one thing. It helps when the bounces are incredibly conducive to goal-scoring, and we mean incredibly. Case in point: Patrice Bergeron's 4-3 goal, which was the direct result of one of the most fortuitous bounces we're bound to see in this Stanley Cup Final, as Zdeno Chara's wrist shot deflected high off the boards behind the goal, up onto the goal, and then down into the crease and right onto the stick of Bergeron.

Ever the opportunist, Bergeron didn't waste the freebie and finished the Rube Goldbergian play off by putting the puck into the goal. Thanks, hockey gods!

That was the wackiest moment in a truly wacky second period, where Game 4 between the Chicago Blackhawks and the Boston Bruins turned into an unexpected track meet

Really, it seemed less like the Stanley Cup Final we've been watching for the past week and more like a game between the Flyers and the Penguins.
