Your Leg is Not Built to do This (I might get sick)
Ellen DeGeneres is holding a $10,000 YouTube talent contest, and revealing the winner today. And this one might be tough to beat. Some girl posted a video where she spins her leg around 180 degrees, so it looks like it's on BACKWARDS. It's actually a montage of her showing the trick to a bunch of different people and freaking them out. She acquired the "talent" after she was diagnosed with bone cancer in 2010, and had to have part of her pelvis removed. Here's a guy saying, "What in the hell!" after the girl did the trick in front of him.
