Not too long ago, Canadian teen Jen O’Shea was diagnosed with bone cancer. After treatment failed to control the disease, her doctors told her that to survive she needed to undergo surgery. Well, that was a success, and what came out of the situation was not only a clean bill of health but also a new talent: she could twist her leg 180 degrees, making the sole of her foot face the ceiling.

Jen recently attempted to win a contest on 'Ellen' by filming the reactions of her family, friends and classmates. She didn't win, but that hasn’t stopped her YouTube video from going viral.

So, take a look, and take one bit of advice: Don't try this at home!
