Samantha insists that Endora zap away the new pony for Tabitha before Darrin gets home. Endora tells her not to worry, the pony IS Darrin. Once changed back, Darrin orders Endora out of the house. At the office, Endora sends a ""live"" framed photo of her that Darrin cannot escape her ever changing expression. A client named Mr. Gregson wants to meet Darrin's mother-in-law, who must be a special woman for Darrin to keep her photo on his desk. The dinner goes well, particularly since Endora has become the queen of charm. After witnessing a tiff between the Tates over Larry's mother-in-law, Gregson suggests that Darrin should open his own ad firm. Larry doesn't like this one bit and refuses to speak to Darrin. It's up to Samantha to set things right between Larry and Darrin.
