Probably a LOT of vodka involved... and that guy didn't look good at all. I saw a "related" video of a guy sitting on one, but when it blew, it blew out sideways. Because these nut-jobs put it in tires, all the energy was blasted UP. I wouldn't be surprised if that guy had serious back problems.
Evidently, Russian humor.
