Jo Jo Jo
Nancy McKeon’s character, Jo, was introduced in the second season. The writers based this character on another popular character from a different sitcom that aired around the same time.
As Nancy stated in an interview back in 1982, “Jo originally was a lot like the Fonz; then they wanted her to be less dominant, which I didn’t want to do… So we talked about it and came up with the way she is now. She has aspects of both characters – she’s not solely one or the other.”
