S2, E20: Dr. Bellows' wife insists on having Jeannie's bottle for her living room. When Tony refuses to part with it, Mrs. Bellows decides to have a duplicate made and promises to return the original. Jeannie is furious when Mrs. Bellows leaves with her bottle. Tony soothes her by going to the workshop to get it back. Jeannie gets there first and pops into the bottle to wait for Tony. Salvatori instructs his son Gino to wrap up the two bottles. When Gino gets them mixed up, Tony leaves with the copy while the original, with Jeannie inside, is delivered to Mrs. Bellows. Tony discovers the wrong bottle. He phones Bellows who tells him he and his wife are going out. Worried that Mrs. Bellows will find Jeannie, Tony and Roger decide to rescue her. They are searching the house when the Bellows return. Accepting Roger's explanation that Tony is sleepwalking, Bellows concludes that he has a compulsion about the bottle. Tony pretends to awaken and switches the bottles. Unfortunately, Bellows does too. At home, Tony tells Roger that the Bellows still have Jeannie, but as she appears, Roger reveals he did a little switching himself.
