You might have bad luck, but nobody's luck is worse than lacrosse player Zack Greer's.

Greer plays for the Saskatchewan Rush, and he somehow found a way to get knocked out out twice in the span of about a second. After he laid a dirty shot that floored an opponent, he got a double-dose of payback. First, a nearby opponent's fist took his helmet off and turned out the lights, then before he could even hit the ground a flying lacrosse ball nailed him square in the face. Ouch. Double ouch.

So next time you feel like life is handing you a bad deal, just be thankful you didn't get knocked out twice in a row. No matter how bad your day was, it went better than Zack Greer's.
