in which Patty and Richard contemplate getting married – which Duke said in hindsight "was not a good idea." The series was cancelled due to disagreements between ABC and United Artists Television (UATV) over filming the series in color. ABC wanted all of its shows for the upcoming 1966–67 season to be in color, while UATV claimed filming The Patty Duke Show in color would be too expensive.

On June 30, 1995, Nick at Nite showed one episode of the series during their 10th anniversary celebration.
