Jeannie (Barbara Eden) creates a "miracle" spot remover to clean a stain on Tony's jacket. The result: the jacket proves to be indestructible, leading Gen. Peterson (Barton MacLane) to demand that Tony (Larry Hagman) give another demonstration of the remarkable remover--a demonstration so disastrous that it nearly gets one of the regular characters permanently transferred to Iceland.
