My Favorite Martian
TV Series: Season 02; Episode #27: "Uncle Baby" (04/04/65)
Ray Walston in "My Favorite Martian" had an AR episode where a rejuvenation ray turns the adult Martian (Uncle Martin) into an infant of approximately nine months in age. The rejuvenated infant "Uncle Martin" is taken to the hospital by Detective Brannigan (the suspicious
erstwhile enemy of "Uncle Martin") as an abandoned baby.
While trying to rescue his friend, the protagonist and reporter (who is the roommate and friend of Uncle Martin) restores the wrong infant to full adulthood with an AB scene of an adult in diapers nursing an entire tray of baby bottles.
There was one very good AR scene at the beginning of the episode when the baby "Uncle Martin" must crouch [he is unable to stand do to the weakness of the legs of his regressed body] on the carpet on his hands and knees while wearing nothing more than pinned cloth diaper.
The regressed Uncle Martin proceeds to paternally instruct his adopted Earth "nephew" from his infantile position on the carpet how to use the Martian rejuvenation ray to restore him to his rightful
age.
