Moses Lanham, a 57-year-old man from Michigan, has become known as ‘Mr. Plastic’ for his unusual ability to turn his legs along with his knees 180 degrees and walk backward.
Mr Plastic discovered his superhuman ability when he was only 14-years-old. He was climbing a rope in gym class when he lost his grip and crashed to the floor, landing awkwardly. At first, he thought something was dislocated, but he soon realized that he could easily turn his lower legs 180 degrees and back again without experiencing any pain. Medical tests revealed that he was able to do this thanks to of double cartilage in his hips, knees and ankles. He has been using this gift to freak people out ever since.
