This video of a Shop At Home TV host hitting himself with a ninja sword is the train wreck you can't turn away from.
While demonstrating a "practice sword", this host decides to show off its features by whacking it against the countertop. But he gets surprised by the kickback on this sword as it bounces back and hits in the body. That sends him dropping to the floor like a rock.
But in true tv professionalism, he keeps talking, while uttering painful noises. Another guy steps in and tells the audience (and the studio crew) that an ambulance is needed.
Notice how no one actually comes over to check on him. We hope he's OK and learned his lesson. "No playing with knives in the house!"
