I remember one summer, when I was 10 or 11, I spent a day at home watching sumo wrestling on ESPN2. I came away from the experience thinking that sumo wrestling was boring and dumb. I would not have been so dismissive if some shit like this had gone down.
What you just saw was three-time World Sumo Champion Byambajav Ulambayar body slamming opponent Kelly Gneiting—who outweighs Byambajav by nearly 80 lbs.—into oblivion at the 2013 U.S. Sumo Open. I assume that a headstone has since been erected at the site of the match, so as to memorialize Gneiting's destruction.
