The Dukes of Hazzard star Johnny Knoxville has laughed off his hardman image, insisting in reality he is a big softie who hates fighting. The Hollywood actor rose to fame for performing crazy stunts on MTV show Jackass - but refuses to get rough when the cameras are off. Knoxville tells Spin magazine, "People think by challenging me they're going to show they're tough. But I'm not tough. "Decent drinker. Not such a bad kisser. But not a great fighter."
