Legs behind head

From Wikimacs

In 2002, Barry Huang was for some reason demonstrating his ability to put both his legs behind his head. During this spectacle, Thomas Chu then came over and took one of Barry's shoes, which he had removed, and proceeded to strike Barry between the legs with it. Though it was not a direct hit, Barry still howled in pain and surprise; perhaps the most comical aspect was that Barry's legs were stuck behind his head and he rolled around helplessly. To this day, Jeffrey Ian Chen cannot even begin to tell the story before cracking up and gasping for air. The event was later parodied in the Group E skit, Space Camp.
