Here's one that will make your stomach churn.
A man has uploaded a video of himself climbing to the top of the Red Gates Administrative Building in Moscow, Russia.
The man -- who does not appear to be wearing any safety equipment -- exits a hatch on the roof and makes his way to the top of the tower via a small ladder.
According to the School of Russian and Asian Studies, the 24-floor building is 133 meters, or 436 feet, tall and is one of Moscow's "Seven Sisters."
This video is among the latest in illegal urban climbing stunts uploaded to YouTube. Earlier this month, a video of teens climbing the Moskovskyi (Moscow) Bridge in Kiev, Ukraine went viral.
But not all climbers do so illicitly. In March, Alain Robert, a French skyscraper climber, had permission from the local authorities when he climbed to the top of the Burj Khalifa in Dubai. The 2,717 foot-tall building has 160 stories and is the tallest in the world.
