The Ropers make their final appearance and Chrissy Snow is mentioned by name for the last time.
Norman Fell had it written into his contract that if The Ropers (1979) didn't last a full season, that they could come back to Three's Company (1976). The Ropers lasted a season and a half. They were later allowed to come back one more time.
Norman Fell and Audra Lindley had returned one last time to the series (Night of the Ropers) a year after their own spin off The Ropers (1979) was canceled. This was also the first episode that Suzanne Somers did not appear in after she was fired.
