Cameron Pilley is a native of Australia who is currently the 16th-ranked squash player in the world. Last week, he set a world record for hitting a squash ball, variously reported at 173 or 175 miles per hour, depending on whether you believe this or what Pilley had to say in the video (not that it makes much difference when it's rocketing right at you at close range). Pilley's brother, Morgan, volunteered to allow Pilley to hit him as hard as he could in the back. While there's no indication exactly how fast the ball traveled, what Morgan's back looked like afterward made it pretty obvious it had to hurt. [Hot Clicks]

UPDATE: Morgan Pilley has posted a photo of his wound to his Twitter page.
