I referee youth and adult Hockey leagues for extra money in my spare time. I was ref'ing an over-enthusiastic bunch of young adults about 3 1/2 weeks ago. I was dropping the puck at a face-off and WHAM! One young-adult took a leaping swing at the puck and missed but connected dead center under my jaw. Split it clean in half plus broke both the joints where the bottom jaw meets the skull. I looked like the Predator from the Predator movie. I have to have a 4 hour surgery to repair my jaw. Had to have a plate put in to keep all the pieces in place. Not a fun thing to go through. I don't recommend it for even the sickest of sadists.
