The action in the episode directly follows that of the previous two-parter "Mary Loves Scoochie", which ended with Dick transforming Dr. Liam Neesam, a malevolent alien played by John Cleese, into a chimpanzee.
Harry meets a woman named Sam working at the store that was robbed, and makes a date with her later that evening.
Harry later sees Sam working at fancy restaurant, but she instructs him to call her Samantha due to the setting.
Sally reveals to Don that she's a security specialist, and puts him through a crash personality alteration course in an effort to improve his effectiveness as a police officer, and guide him back to the force, making their parting one of respect and camaraderie rather than one of lost love.
Tommy feigns ambivalence about the mission's end but when left alone in the kitchen he loses his normally cool demeanor and breaks down into uncontrollable sobbing over the team's pending departure.
In the ending moments of the series, the family sits in the Rambler and the same spot where they first appeared, and discuss all the things they're going to miss on Earth, which prompts Mary to panic and decide that she can't go with them.
Dick escorts her out of the Rambler and agrees to perform a memory-wiping technique on her, one that erases her memories of him but leaves the feelings associated with their love still in her mind.
But in the final scene, the emotions from the actors (especially John Lithgow, French Stewart) were genuine as they really were upset about the series coming to a close.
The Boston Herald's Monica Collins said it was "charming",[4] and Mike Duffy of the Detroit Free Press called it "sublimely ridiculous to the end, shamelessly silly and proud of it".
