Yes, I just posted something from The Daily Wh.at, but I watched this immediately after and I about lost my poop inside my underpants.
From the dude who runs The Daily Wh.at:
Awesome People Being Awesome of the Day: Remember those shots of Tom Cruise jumping off the Burj Khalifa in Dubai for Mission Impossible 4? Well, prior to that, professional stuntmen Brett Smrz, Gregg Smrz, and David Schultz scaled the world’s tallest skyscraper as part of a scouting mission for the film, minus the emasculating safety of a climbing harness.
That is, unless you take into account the bracing effect of their massive brass balls.
The only issue I have with the above is that the guys admit to be harnessed in. They hid their harnesses for the effect of the video.
Other than that, my palms got sweaty and I was short of breath just watching this video.
