Ball Boy Takes A Serve To The Groin (Video)
If you're a male you understand the importance of protecting your jewels. Unfortunately for this dude, a tennis ball heading your way at over 100mph doesn't give you much time to react. The best part is how long it takes him to realize how much pain he is in. Everyone loves watching a shot to the groin. Watch the whole thing.
