Talked about is the famous leather jacket worn by Fonzie. Apparently, the network did not want him to wear a leather jacket because it symbolized gangs. So they compromised and said Fonzie could wear it only when he was on his motorcycle...which the writers creatively used in almost every scene (in the house, diner, even the men's room). By the second season, he was wearing the jacket full-time. It is now on display at the Smithsonian.
