In this first episode of I Dream of Jeannie's third season, soft-hearted Jeannie (Barbara Eden) feels sorry for the chimpanzee who is slated to go on a NASA moon shot. To save the simian from this fate, Jeannie transforms him into a human being (hilariously portrayed by Larry Storch). Unfortunately, the spell backfires on Tony (Larry Hagman), who is turned into a chimp and slated to take the moon trip in the real monkey's stead. (Reportedly, the decision to name the chimp "Sam" was a deliberate slam against I Dream of Jeannie's rival "magical" sitcom Bewitched, which of course starred a beautiful witch named Samantha).
