In a hospital hallway, 16-year-old Hunter Keith challenged a physician's assistant to a floss dance-off. After his appendix burst, Hunter had to stay at the Children's Healthcare of Atlanta for nearly two weeks following surgery. "Hunter started showing us videos of him dancing," explained physician's assistant Kami Gudger. "Somehow we decided before he was going to leave he was going to have a dance-off."
