Matthew Perry did something to Chevy Chase that I imagine a bunch of people who work on Community have wanted to do. The Friend played a charity doubles match with Fletch about a decade ago. When Chandler Bing served the ball to the other team, he binged Chase in the racket and tennis balls with the optic yellow ball that was traveling at 115 mph. Well at first it looked like Clark Griswold took it well, but then he fell to the floor in pain. Four men had to pick him and he was later taken to the hospital to make sure he was OK.
Considering that his voice is still deep, I think he is OK.
