"Jeannie-Go-Round" marked the eighth appearance of Jeannie's brunette sister, this time posing as Jeannie to wreak havoc for Tony before Dr. Bellows and wife Amanda. Forced to attend a nightclub with the Bellows, Tony has to leave his disappointed genie at home, as planned by Jeannie II, who substitutes for the scheduled singer (Barbara Eden belts out the song "Power On"). The real Jeannie is unaware of her sister's deception, and must obey when her angry master orders her back into her bottle. This affords Jeannie II the opportunity to sashay around, driving Tony insane by appearing and disappearing at will. Even Roger thinks he's cracking up: "I'm not deserting you, I'm leaving!" Amanda Bellows continues to flirt with Tony in front of her husband, both Jeannies facing off for the chaotic climax. Veteran voice-over artist Dave Barry scores plenty of laughs as himself, the comedian in the night club.
