I got a weird sensation in my groin after watching this video.  You know the kind you get when you're 2000 feet up...hanging off the side of a building.   Well, these guys are badasses...or just nuts, because that's just what they do in the video.  The 2nd tallest building in the world (which is still under contstruction).

Watch the video and see if you get the same "tingley" sensation, as if you are actually there.
