"Operation: First Couple on the Moon" was the fifth appearance of Jeannie's sister, whose latest attempt to steal Tony involves posing as Dr. Rita Walters in a series of tests to become his companion for three months on the moon. Professor Henrietta Swanson (Katherine Reynolds), pretty enough to moonlight as a scantily clad cocktail waitress, is naturally targeted by Major Healey and his hormones. LAREDO's William Smith plays Professor Swanson's hulking fiancée Turk Parker, an all pro linebacker who puts the fear of God into Roger. Jeannie believes that being literally bottled up for months will be anathema for her genie sister, but she shows no signs of fear. Katherine Reynolds went on to play Chester Tate's secretary Claire on the popular 70s comedy SOAP.
