Okay, we're not saying there's an upside to cancer, but this is pretty cool.

A few years ago, Canadian Jen O'Shea underwent a lifesaving operation after having been diagnosed with bone cancer. 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.

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

Hopefully we don't have to say this: don't try this at home!
