Apparently, playing dodgeball on the set of Glee can be hazardous to your health. In this behind the scenes video, Kevin Mchale reveals that Naya made his forehead bleed. He then apparently took out his aggression on Darren Criss, attacking him with his wheelchair so he needs an icepack. Dodgeball is a vicious game. "Today, we're hitting people in the face with balls." Fun!
