This video definitely isn't awesome or cool, but it's amazing in the sense that it's the craziest YT video I've ever seen and kind of messed up.
A boating - diver accident caught on cam, you may want to avoid watching if you're easily bothered by blood. This is pretty disturbing. It happens at around 3:30 if you're impatient.

Some sick final destination moment if I've ever seen one.
