A vacation that the Stephens were supposed to take is scrapped when Darrin has to work. Endora takes it upon herself to separate Darrin into two different personalities: his work side and his fun and spontaneous side. While the working Darrin is concentrating on his job, the fun Darrin is concentrating on partying until he drops. Of course, all of this takes a toll when the Working Darrin bores Larry and his new client and Samantha acts as mother instead of wife to Darrin, the party animal. Samantha wants Endora to put the Darrins back together again, but ends up doing it herself.

Just when you thought it was safe to use your magic, CHARLIE LEACH returns! He did keep his word in episode 65 and threatens to expose Samantha and Endora. This time, he kidnaps a cat which is, in reality, an attractive client named Toni Devlin whom Darrin is having a business lunch with. Leach makes a deal with her: the transformed cat for a million dollars. She tricks him by giving him a ""money tree"" that sprouts dollar bills, and turns him into a mouse! Charlie returns teh cat and Sam tries to find Endora to turn Toni back into a human.

Darrin is refused a new account in McMann and Tate, but the next day, Larry gives Darrin the account. Darrin thinks that Samantha used magic to sway Larry's decision and tries to do everything to back out of it. Even the client, Mr. Waterhouse, likes Darrin's attitude and ability. Darrin feels that Samantha is behind all that has happened to him. To teach Darrin a lesson, Samantha uses magic to turn their house into an expensive mansion with servants to boot. Darrin tells Sam that he wants to earn things his own way, which is exactly what he has been doing all along.

When Samantha gives away Darrin's favorite jacket to Goodwill, it ends up tearing the marriage apart. The Stephens get counseling from the Tates and Endora conjures the famous Sigmund Freud to help them all out.

A chair is smitten with Samantha and proves it by hurting Darrin every chance it gets. The new clients, the Cosgroves, are crazy about the chair, especially Adelaide who will not let McMann and Tate sign their contract. Of course, the chair ends up hating Adelaide for her behavior. Samantha gets to the bottom of this mess. The chair is actually an old boyfriend whom Samantha rejected a long time ago.

Samantha applies for a loan to tear down a gazebo and to construct a rumpus room. The nosy bank inspector comes down to check out the land and sees a live baby polka-dotted elephant mistakenly conjured by Aunt Clara. The baby elephant was from a toy that Tabitha had wanted in the park. Larry comes by to see what the fuss it all about, and Samantha tries to hide the big baby from him.

Darrin is mesmerized by the moon footage on TV and shows Samantha, but she is not interested because she has been there before. Endora wants Samantha to go shopping with her- in Tokyo! They go to a little place where they get warlock tea. Darrin finds the tea and thinks that Samantha really did go to the moon. He has it analyzed and the druggist brings his cousin from Nassau County (Darrin thinks it is NASA) to give him the results: It is really tea, not moon dust.

Darrin's old college rival, Charlie Harper, has a very successful life and wife Daphne loves to brag about it--their castle has a moat! During a weekend visit to the Harper's latest home, Samantha unintentionally upstages Daphne, creating tension between the two. Finally, Samantha plays Daphne's game, and zaps a loaded jewelry case and a mink coat (made of identical twin mink pelts.) Darrin's ego is hurt. How can he compete with Samantha's witchcraft? To make amends, Samantha gives the coat to Daphne after she insists that the Stephens sell it to her. Samantha reassures Darrin she could zap up mink coats all day long, but she could never zap up another Darrin Stephens.

Darrin is warned by Sam not to kiss a beautiful client named Terry Warbell. There is a good reason: she is a magic crone who steals the youth of poeple that she kisses. Of course, Darrin doesn't believe Samantha, but he sees for himself when Terry turns into the old hag.

Aunt Clara's morning paper says that Larry Tate breaks his leg while on a honeymoon with Louise. Samantha and Darrin rush to his honeymoon spot and try to protect Larry, who tells them to leave him and Louise alone. Then they find out that he broke his leg ten years ago and they are on their second honeymoon!

Darrin has a bad cold and Dr. Bombay treats him with some pills. Of course, these pills have a horrendous side effect- it makes his voice higher!

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.

Remember Sheila Sommers from the pilot? Well, she's back and Larry wants Darrin to go with her to get her father's account with McMann and Tate. At a dinner party, Sheila is up to her usual tricks, and Samantha unleashes a few of her own.

Samantha wants to know what life would be like if she and Darrin had never met. Endora shows Samantha that Darrin would have married Sheila and become a part of her millionaire father's family. Darrin likes her, but he doesn't love her. On cue, Darrin meets Samantha and the rest is history.

Tabitha brings out Prince Charming and Helen, Darrin's cousin, falls for him. Her fiance, Ralph, doesn't like this arrangement one bit, but Larry likes it and thinks that the prince will be perfect for TV commercials. To sway the prince away from Helen, Samantha pops in Sleeping Beauty.

A simple case of mistaken addresses is the issue for this episode. A flipped number in their home address creates confusion and artificial grass is delivered on their lawn. The real owner wants to know what happened to his artificial lawn and finds out that Darrin has it.
