This is a little rough to watch if you're a dude. Hell, it's probably difficult to watch if you're chick, too.

During a tennis match, one of the players served the tennis ball with all of his might and accidentally hit one of the ball boys... in the balls.

Isn't that just one of the worst things ever? This kid took it like a champ though, despite the speed of the tennis ball being around 120 MPH or so. Two thumbs up to him for managing to do his job before tending to his testicles.

This has to be one of the most painful things ever. It's definitely painful to watch.
