You know what the most exciting thing about Happy Days turning 45 is? It’s cool. And being cool is… well, cool. That life lesson was instilled on a generation of TV watchers by that 1950s-set show’s Henry Winkler as Arthur “Fonzarelli, aka “The Fonz” or “Fonzie.” Wearing his leather jacket and oftentimes on his motorcycle (even in his apartment), he helped turn the Ron Howard series into a pop culture sensation. He also made famous phrases like “Ayy” (accompanied by two thumbs up), “Correctamundo,” “Exactamundo,” “Perfectamundo,” and, in his own unique way, “Cool it!” People watching Henry on HBO’s Barry may find it hard to believe that that’s the same guy who played the Fonz, but it is.
While once being interviewed by radio station WXOU, Henry addressed the impact Fonzie had on him: “He gave me a worldwide recognition, gave me a job in the very arena that I dreamt about. He was fun to play. I loved the people that I acted with. He put a roof on my head. He put my children through school. He created good will. He gave me the key to the door — now, once I walked through that door, I had to create it — but he gave me the key to the door to my future.”
