Man with Massive Balls Scales 900-Foot building Without Rope and Jumps Off

As soon as I started watching this video, my hands began to sweat.

Daredevils like this are a complete mystery to me.

Austrian Michael Kemeter, 23, recently climbed a 900-foot tower in China – without using any rope.

Then, just to remind everyone that he's completely crazy, he jumped back to the ground.
