After Samantha finds out that the flowers were delivered by Dan, she discovers the leak and the bug! Sam and Endora both give Dan a hard time.

Hey, who turned out the lights? Aunt Clara knocks out the entire Eastern Seaboard's electricity with her magic. Her only hope is her old boyfriend Ocky, who can keep the lights on by having his arms raised. Since they are the only house that mysteriously has power, The Tates and their new client Mr. MacElroy go over to Sam's house. Aunt Clara tries her best to keep Ocky hidden from view by hiding him in the closet. Darrin discovers him, but all he sees is a pair of walking shoes, a perfect campaign for his client!

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.

Aunt Clara tries to help Samantha fix a lamp, and conjures an electrician, none other than Benjamin Franklin. Darrin is amazed at Franklin's appearance and Larry thinks it is a great advertising campaign for his new client Franklin Electronics.

Out on bail, the Stephens return home, but now, Ben disappears! Clara has remembered the spell........ to be continued.

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.

Samantha and Endora take Tabitha to a taping of Ho Ho, the Clown, where Darrin's newest client, Solow Toys, is the sponsor. Because Tabitha is related to Darrin, she is prohibited from the contests. Endora does something about that and makes Ho Ho fall in love with Tabitha and gives her all the prizes. This jeopardizes both Darrin's job and causes the show to be cancelled if they don't do something soon. Samantha comes up with a terrific plan: Tabitha's appearance on the show was a publicity stint for a new Tabitha doll.

Samantha is doing a painting for an art gallery contest, and Endora doesn't think it is up to snuff. So she takes it upon herself to change the painting so Sam can win. And Sam does win, but she doesn't want the prize because of what her mother did.

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.

Poor Darrin. Due to Endora's spell, everyone hates him. When Darrin's job is on the line, Samantha wants Endora to remove the spell.

If it is not the Tates that the Stephens are protecting from Tabitha's secret, it's the elder Mr. and Mrs. Stephens. As usual, Phyllis and Endora do not get along, and she thinks that Sam and Darrin are having a lovers' quarrel.

Darrin has a hard time with an eccentric client named Madame Maruska, whom he thinks is Endora. Because of his faulty knowledge, he loses the account. When he learns that Endora did not mess with him, he apologizes to Madame Maruska and still doesn't get the account. It's up to Samantha to win her over using magic.

Phyllis sees Jack and is very confused about what is going on. Samantha finds out that Tabitha twitched herself into the storybook and goes in to get her back. She finds Tabitha shrinking the story's giant and messing up the entire story. Samantha tells Tabitha to put everything right back where she found it and brings her home.

A year after Aunt Clara passed on, Esmerelda carries on her memory by being a bumbling witch as well. Esmerelda sneezes up a whole lot of trouble when Darrin has a prospective client over to look at ad layouts. Then, when she gets nervous, she fades out. Darrin uses Esmerelda's magical snafus to good use when he presents a unicorn as a design for the client's car company. Samantha tells Darrin that Esmerelda will only visit when she is called.

In the very first day of their Salem vacation, Darrin and Samantha gets into serious trouble. While taking a tour of the House of the Seven Gables, a magic bedwarmer follows Samantha. The bedwarmer even follows them to their hotel room and the tour guide calls the police because she thinks that the Stephens stole the bedwarmer. Darrin gets taken to jail, leaving Samantha to get him out and to get to the bottom of this bed warmer mess.....

The Stephens come home, only to have Esmerelda blink Samantha back to Salem- circa 1600's! Darrin has to go back in time and bring Samantha, who has no memory of who he is, back home. He has to place a coin on Samantha's head and have her say an incantation so she can remember again. He tries to get her attention and ends up getting accused of witchery! Samantha puts two and two together and goes along with the incantation.

Darrin's friends, Keith and Dorothy Wilson who happen to be black, invite their daughter Lisa to stay with Tabitha on Christmas Eve while they go away. Lisa and Tabitha want to be sisters because they get along so well with each other, but are discouraged when someone tells them that they can't be because Lisa is black and Tabitha is white. Of course, this gets out of hand when Darrin's newest client, Mr. Brockaway, visits his home. Lisa is asked to answer the door, and Brockaway gets a shock when he sees her, thinking that she is the Stephens' child! He turns Darrin down because of his bigotry. Tabitha lets Lisa in on her witchcraft and uses wishcraft to blink polka dots on both her and Lisa. Samantha then tells them that they don't have to look the same to be sisters because they are sisters at heart. Then, after a well-deserved lesson from Samantha, Mr. Brockaway admits that he is a racist and wants Darrin to handle his account as his apology.

Samantha goes away for a 10,000-zap checkup and Serena takes over for her at home. All trouble ensues when she weasels her way into Darrin's life when he is trying to impress another seroius client. Samantha comes home to witness Serena acting up and straightens things out. All is well, until one of Tabitha's toys, a troll, comes to life and starts embarrassing Darrin in front of his prospective client!

Endora says that Darrin is pig-headed and proves that by blinking a pig's head on his body! This is a catastophe for Darrin, but turns out to be a great ad campaign for his new client.

Darrin learns that Serena is not to be messed with when she turns him into an ape.

Endora accuses Darrin for being too cheap when she notices Tabitha and Adam playing in a wading pool when they should have a real pool. She blinks one up, and Darrin takes an unnecessary swim! Darrin warns Samantha to keep Endora at bay. Than, he finds a bag full of money- $100,000 to be exact! Darrin thinks Endora whipped up the cash, but it really belongs to a thug who wants his loot back.

Samantha cleans up the house by her magic, and Darrin catches her! Feeling guilty about herself, she gets the hiccups and pops up many, many bicycles! They have to hide the magic evidence because Darrin's mom is coming. When Phyllis does come, Darrin pushes her upstairs so Sam can call Dr. Bombay to get rid of the bikes. But her hiccups come back when she and Phyllis are shopping. Instead of bikes popping up, an item in the store disappears! When Phyllis and Samantha are doomed to go to jail, Dr. Bombay comes back and gives her the right spell.

Phyllis is beside herself when Samantha makes her think that she has magic powers. It takes Frank to be turned into a mule and a mock seance to put some sense into Phyllis.

As the final season begins, Samantha and Darrin take another vacation- all around Europe. Their vacation begins in the Tower of London where they are taking a tour. As they are touring, Samantha gets a call from one of the paintings- a nobleman on horseback. It seems that an evil witch had placed a curse on the nobleman, trapping him into a painting for a thousand years. The witch and the noble were destined to be married during Henry VIII's reign, forgetting that he was already married, the reason why he was placed in the painting. Being a nice person, Samantha lets him out. The moment he is released, the evil witch Malvina the Terrible appears. As punishment for breaking the curse, Malvina sends Samantha back to Henry VIII's time period. Once there, Samantha forgets who she is or why she is there. She comes across a group of instrument players and joins them in entertaining the infamous king, who falls for her. Darrin gets Endora to help him find Sam and save her with a kiss so she c

The reporters go crazy about the Loch Ness Monster, and Bruce wants to be a monster again. So he changes Serena back and Serena returns the favor by sending him back to the way he used to be, but with a little understanding about how important he really is.

Samantha and Darrin are now in lovely Paree and Endora is home with Tabitha and Adam. Maurice comes by the house and finds out that the Stephens are vacationing in Europe. He is mad because they should have stopped by in London to see how he was doing. Endora flies to Paris to warn Samantha and then Maurice appears in a scary cloud of smoke. Out of rare kindness, Endora zaps up a fake Darrin who charms and pleases Maurice. Everything just seems all right until the real Darrin comes in. Maurice notices the trick and sends poor Darrin to the top of the Eiffel Tower. Unbeknownst to him, his very appearance there makes a perfect advertising campaign for one of his clients who runs a travel agency.

Tabitha speaks out about violence on TV. She pops on a TV show to reprimand two aggressive puppets. Of course, Darrin happens to be watching the show and tells Sam to get Tabitha off the TV. The sponsors say otherwise and Tabitha becomes a TV star. The Stephens are dead set against this and Sam makes sure that the sponsor, Mr. Silverton, brings his own daughter to the show for back-up.

Maurice helps Adam by giving him powers so that he will not be taken away. Adam is indeed normal, but he does have his own powers tucked away somewhere.

Esmerelda's magic seems to be all wrong and is a failure as a witch. Larry says that a client of his needs a babysitter for the evening and gets Esmerelda to do the job so he can sign the contracts to win the deal. Esmerelda shows the Norton's child, Ralph, some magic and No one believes him when he tells all about it. As a result, Esmerelda is fired and Larry loses the Norton account. So Samantha sets up a dinner party with Esmerelda as a magician. Once everything is cleared up, everyone gets what they wants: The Nortons are friends again and Larry wins the account.

Serena visits Samantha because she is stripped of her powers. She then falls for Darrin's newest client Harrison Wilcott and decides to go out with him.

"I know that Tabitha is ready for school, but is school ready for Tabitha?" warns Sam. Tabitha attends school for the first time, and has a pretty hard time because a boy is messing with her. When he refuses to give up, Tabitha turns him into a frog. The teacher Miss Peabody gets on her about the frog and tells her to put it back in the class terrarium. Tabitha grabs the wrong frog and Samantha pops into the school and changes the frogs. When the right frog is brought home, Tabitha changes it back before the boy's mother finds out.

Tabitha has to take a test to prove her intelligence and is very nervous. Endora helps her out by puuting a spell on her, making her a super genius! Miss Peabody, the teacher from episode 246, is amazed about Tabitha's knowledge and tells the principal about it. Samantha find out about this, and tells Endora to take the spell off Tabitha. Miss Peabody will not back off, and she catches Tabitha and Adam using their powers one day. Samantha catches Miss Peabody trying to be like Gladys Kravitz and gives her a lesson about snooping she will never forget.

Darrin needs help on an advertising campaign and Samantha offers her help using her own mind. Darrin thinks that she used witchcraft for the ideas she gave him and decides not to use her ideas. Darrin comes up with some ideas of his own and are rejected by the client Mr. Benson. He thinks witchcraft was used in the decision, too. Call it deja vu when Darrin shows Benson Sam's ideas ande Benson rejects them as well. Darrin feels like a total jackass and apologizes to Samantha, coming up with a stellar slogan for Benson.
