I Dream of Jeannie - Season 4 Episode 24
Jeannie-Go-Round

Locking Jeannie in her bottle, her wicked lookalike sister Jeannie II trails Tony to the Cocoa Beach Cabana. In her efforts to win Tonys affections, Jeannie II also replaces the nightclubs regular singer and renders a seductive ballad ("Electric Days, Electric Nights"). Alas, from this point forward everything goes wrong, with Tony being publicly embarrassed and Dr. Bellows virtually being hand-delivered enough evidence to wash Tony out of the space program!
