Invisible House for Sale

S4 E16: Tony keeps Jeannie away from the secret island. Roger feels that Tony would have more time for Jeannie if he didn't own his own house. While Tony meets with Mr. Winkler, a new administrator, Jeannie blinks up a "For Sale" sign. Merkle, a realtor, brings Mrs. Winkler but she feels the house is too small. Posing as Mrs. Uppington-Smythe, Jeannie blinks up magnificent additions. Mrs. Winkler calls her husband at Tony's office. Stunned that Winkler plans to buy his house, Tony detains him but he phones his wife to put down a deposit. At home, Tony finds a "Sold" sign. Jeannie pops him into as apartment and welcomes him to their new home. Tony expresses delight at the bikini clad girls at the pool. Jeannie pops them back to the old homestead.. Jeannie feels if she removes the luxuries, the Winklers won't buy the house. After Tony instructs her to return the deposit without letting Mr. Winkler see the house, Jeannie blinks it into invisibility. Merkle and Winkler stare as Roger crashes around the invisible house. Winkler reports the empty lot and Dr. Bellows recognizes Tony's address. Jeannie restores the house including the extras. Returning, Mrs. Winkler thinks her husband is hallucinating. Since Jeannie has blinked the house back to normal, Mrs. Winkler hysterically describes the "estate" and Mrs. Uppington Smythe. Bellows is thankful that someone also seems to be crazy for a change.
