Jon Fitch
Jon Fitch appeared on the November 5, 2008, episode of "MythBusters", "Coffin Punch". The MythBusters were attempting to determine if someone could punch their way out of a coffin. For his part, Jon Fitch laid on his back and punched up into a sensor, attached to a punching bag that was a few inches above Fitch, allowing his arm only three inches of travel before contact with the sensor. The sensor read that the power behind Fitch's punch was just under 1,500 pounds of force (6672 N).
