Meet Cameron Pilley, professional squash player, who just last week hit a squash ball at 175 miles per hour, setting a new world record. Rather than showing you the record-breaking event, however, the Aussie athlete recreated his famous serve while aiming the ball at his (willing) brother’s bare back.

The resulting damage is NSFL enough that you might want to stop the video before the 1:16 mark if you get queasy easily.
