At this point, we've all seen the insane Russian dudes who dangle off of tall things. But that looks like child's play when you see these Ukrainian guys scale the second tallest building in the world. Like, they literally go to the very top.

The building in question is the spirally Shanghai Tower, and it will soon be 121 stories tall. That's over 2,000 feet of steel and glass. But, frankly, it just looks like these guys are climbing through the clouds, looking down onto some Jetsons-inspired future. Thank God they lived to blog about it. And Instagram it.
