Nascar driver Cale Yarborough was 100% insane. He once wrestled a bear, simply because he was dared to. He caught water snakes with his bare hands and was once bitten by a rattlesnake. He jumped from an airplane and his parachute didn't deploy until he was 200 feet from the ground. He walked away unscathed. In Nascar's first televised race, he started a fist fight.
