 "Legs" was successful as a one time special when it aired in May 1978; therefore, NBC provided a berth for the series on its 1978 fall schedule.However, the network talked with Marshall about adding more of a family appeal to the sex-farce sitcom, which he eventually agreed to.Marshall added two young kids to the cast, and hired another one of his "Happy Days" actors away, Scott Baio, who had also joined the cast of that series in the fall of 1977, along with Lynda Goodfriend.
