Fonzie

Arthur "The Fonz" Fonzarelli (Henry Winkler[?]) was a character in the American sitcom Happy Days. He is a leather jacketed[?] biker and mechanic. Although he is a high school dropout, he seems to be almost superhuman in his skills, wisdom, sexual attractiveness and abilities that make him a much admired character in Milwaukee, Wisconsin. The leather jacket is now in the Smithsonian Institution.

Originally, according to ABC, Fonzie was supposed to wear sweaters, except when he was around his motorcycle in the interests of safety. So, the producers of Happy Days put Fonzie around his motorcycle all the time so that he could wear the leather jacket all the time.
