The bad news is that this video is about actual water sports, not the sexy kind you're familiar with. The good news is that a whole bunch of people get hurt.
After watching this, I've decided that the greatest water sports wipeouts begin on water, but end on land. And I'm a connoisseur of thrill-seekers wrecking their bodies for the greater good of Internet humor. It's one of my passions, like hating the Spurs or disappointing my parents.
