Sure, the footage of those Russian daredevils climbing the world's second tallest building was impressive. But it pales in comparison to this, rock climber Alex Honnold tackling a 2,500 foot cliff without a rope. The climb, which again, was done without a rope or safety harness, took more than three hours to complete.

Here's something you should never watch if you're afraid of heights: A group of Russian daredevils filmed themselves climbing (and hanging from) the world's second highest building, the still under-construction Shanghai Tower. It's absolutely terrifying.

Look at the Yeah Yeah Yeahs, just having a joyful time atop the Empire State Building! It's their music video for "Despair" and also the first music video to be filmed atop the skyscraper. The view is the view!

In Soviet Russia... you film your friends scaling narrow steel beams—which are conveniently located 900 feet in the air—without any safety equipment. And then, if you don't die while doing so, you upload it to YouTube. Watch inside.

Observe a pair of workmen climbing a 1768 ft. broadcasting tower to do repairs. Note that they do it all free-climbing style, without safety ropes or anything. Look alive, coal mining. You have a competitor in the Terrifying Jobs Contest.
