Henry Winkler is amazed at the longevity of his acting career. "It is almost impossible to grasp that, me, not somebody else, me, I did this for 50 years," he told Salon. The icon, known for playing Arthur Fonzarelli (the Fonz, Fonzie) on "Happy Days" and most recently Gene Cousineau on "Barry," said that even after 50 years, he still gets scared with each new role. "You get it, then you're elated for about 10 minutes, and then you go, 'Why did I say yes? I don't know how to do this anymore."
