At the beginning of the 1964–65 season, "The Lucy Show" went through a significant staff change. Elliott Lewis left the series as executive producer and was replaced by Jack Donohue, who served as producer and director. With the absence of Carroll, Martin, Weiskopf, and Schiller, Ball hired veteran comedy writer Milt Josefsberg, who had written for Jack Benny, as script consultant. Under Josefsberg's supervision there were no permanent writers for the series and different writers were employed each week (among them, Garry Marshall). Ball persuaded Weiskopf and Schiller to return and write four installments.
