A Russian gal stripped down to her underwear and did a cannonball for a polar bear plunge. But it HAD to be a prank. I'd assume the guy filming it didn't tell her that the lake was frozen over. Either that or they're both morons. I feel like I would have stuck my toe in the water to feel how cold it was, or that you'd notice waves in the water. The more I talk myself through this, the more I'm leaning towards them just being morons lol.

Reportedly, the gal broke her ankle. Check out the video below...
