During this clip from my full interview with Steve-O on my new podcast "The Check Up with Doctor Mike", the legendary Stephen Glover from Jackass shares the details of his most painful injury from his decades-long career, the third degree burns he got from a stunt doing "snow angels" in jet fuel. He also hits on his biggest regret, which is the years he went not flossing, and how it's harmed his gums later in life.
