Are these people out of their probably-illegal-substances-driven minds? A snowmobile double backflip? How many people have been crushed doing this? No idea. But I just love to watch it.

The double jump was made by Levi LaValle at the Winter X Games on a 450-pound Polaris snowmobile. I'm more the giant Antarctic snowmobile type, the one that can carry planes and have a small apartment inside, but I can appreciate the absolutely nutterini risk this jump involves.
