Here in the U.S., Boston's mayor is up in arms because citizens are jumping out of windows into the snow. Well, don't let him visit Russia, where dudes are setting themselves on fire before jumping into the snow.

But that's almost tame compared to the below video of a Russian man feeding a wild bear through a home window. And we're not talking about dropping the meat from a second-story window. This guy is doing it face-to-face, his hand mere inches from the beast's mouth.

At one point he slaps paws with the massive bear, and tries to tap it on the nose, in keeping with the law of Russian YouTube videos, which demands that any recorded activity be made as dangerous as possible.
