Unbelievable… Is that really him? Clint Howard played the role of Leon, the most adorable sandwich eating cowboy on the Andy Griffith Show. You may recognize him as the brother of Ron Howard from their signature hairstyle, but their appearances aren’t very much alike. Adulthood gave Clint a peculiar look that scored a number of uncanny movie roles. He mainly takes on crazy characters that make you cringe when they’re on screen.
