Sam Hilliard, a truant officer, visits the Addams family because neither of the children has ever set foot in school. He convinces Morticia and Gomez to meet with the principal, Miss Comstock. Miss Comstock, who doesn't think much of Mr. Hilliard, persuades the Addams to put Wednesday and Pugsley in school, but also asks Hilliard to revisit the Addams home. The Addams children are disturbed by the Grimms' fairy tales that are read at school; they think that dragons are really being killed. Hilliard is frightened by the Addams, especially Lurch and the loud gong that ...
The Addamses go into crisis alert: Much to their horror and shame, Pugsy shows a sudden keen interest in joining the Boy Scouts, going so far as to also start raising a puppy. There's nothing for it but to call in a child psychologist to save the lad and family honor from these bizarre new fascinations. Dr. Black recommends indulging the boy's new directions for a while - strange as they might seem - but when he's called in for an emergency visit and notes the decor of the Addams house (not the camping equipment piled high on the living room floor), he gets the wrong ...
Fester's been sly and secretive lately, more than usual, and has also taken to intercepting the daily newspaper deliveries. He's been scanning the lonely hearts columns looking for a bride. Fester finally fesses up and writes a letter, with Gomez happy to snap the picture to adjoin it. Days pass without a response. When Miss Carver appears at the door, she's mistaken for Fester's correspondent - a desperate wanna-be housewife with suitcase in hand ready to move in. She's actually a door-to-door cosmetics saleswoman, and her smooth and mildly seductive sales pitch, ...
Election day is nearing, and Gomez is getting very excited. He puts up all his old campaign posters; notably, all of Gomez's favorite candidates were losers. Sam Hilliard is running for city council, and Gomez throws his support behind the man. Hilliard is eager to get his hands on Gomez's campaign contributions. However, Gomez declares that he'd like to see the money spent in certain ways. After hearing some of the Addams' suggestions, Hilliard wishes they would stay away from his campaign altogether.
Pugsley and Wednesday attend a birthday party for neighbor Harold Pomeroy. Though Morticia instructs her children to be modest about their advantages, it's not an attitude reflected by the Pomeroys, who call them kooks and proclaim them inferior. Incensed, Gomez hires Mr. Pomeroy's genealogist, Professor Simms, to examine the Addams' family tree for ancestors to flaunt at them. In the interim, Mr. Pomeroy completely changes his manner due to oil he thinks he's found on land owned by Gomez. Before the two meet up to discuss business, Simms spills the beans on several ...

Meanwhile, Morticia aspires to join a social club for women, The Ladies' League. When the ladies visit Morticia at home, will Gorgo's style of service impress the guests?
It's Halloween at the Addams' house when a pair of hold-up men come in for refuge after their getaway car runs out of gas. As police intensely comb the area, criminals Claude and Marty, accepted as party-goers, put up with the creepy household's holiday festivities as best they can, till Gomez' desk full of ready cash catches their eye.

When Moticia's childhood friend, Lionel Barker, visits, Gomez views him as an old beau and current rival. Fearing he and Morticia might run off together, Gomez hires Mildred, an awkwardly man-crazy maid, to pull Lionel from Morticia, which doesn't work. When Morticia catches Gomez giving Mildred love lessons, she thinks her marriage is on the rocks. What neither realize is that Lionel's a white-collar con-man out to bilk Gomez.
Newlyweds Hubert and Amanda Peterson move into their delightful new home, but when they find themselves right next door to the Addams estate, they straightaway want out of their one-year lease (especially after Uncle Fester's surprise "Welcome to the Neighborhood" visit through their living room floor). Unfortunately for them, the owner is none other than Gomez Addams, whom they must grin and bear for as long as it takes to be released (if ever).
Wednesday decides to run away from home but goes only as far as Pugsley's bedroom so she can watch the outcome. Not knowing this, Morticia phones the police to report her missing but afterwards discovers the ploy. She and Gomez decide to apply psychology to teach the little deceiver a lesson, but it only prompts their little girl to run away for real, soon winding up at police headquarters. Having responded to the initial call of the missing girl who wasn't, and now being delivered the missing girl who isn't, the already overworked and overwrought Sgt. Haley of ...
For Gomez, things have gotten a bit same-old-same-old, but that ends when two cynical Russian dignitaries visit. Displeased with the preplanned tour devised by Mr. Harris, they decide to visit a typical American home at random, with random chance - much to Mr. Harris's grief - sending them to the Addams house. There, they take note of all the astonishing things they see. In the end, with their view of America radically altered, they decide it's much smarter to remain friendly with such an advanced nation than not.
Cousin Melancholia visits. Abandoned by her fiancé, she needs a man. Meanwhile, the firm of Ferguson-Riche & Fisher wants their Mr. Harvey to broker a deal with the Addamses since he's the only one among them who's dealt with them before (a fact which leaves Mr. Harvey repulsed at the thought and determined to resist further contact). When the Addamses learn he's a bachelor, they're not only eager to meet him but ready to set the wedding bells pealing and heartily welcome him into the family before he can say yes (or anything else).
Lurch receives his annual invitation to The Butlers' Ball, which he ignores as usual because he can't dance. Morticia is determined he accept this year's invitation to avoid the reclusive direction in which he's headed. To that end, a dance teacher is hired, but when that doesn't work (due to frequent fainting spells), the whole family rallies to Lurch's cause, to the endangerment of innocent furniture and healthy vertebrae everywhere.
When an outraged art critic recommends that Mama get a teacher to help her paint better, Gomez gladly hires none other than Picasso for Mama. Not Pablo Picasso, Sam Picasso, a penniless non-talent who's more than willing to be flown to affluent America to teach in exchange for free room and board. Despite outside opinions to the contrary, Gomez believes Sam is an undiscovered master. Consequently, Sam soon finds himself locked in the Addams' basement until such time as he "finds himself" and starts cranking out masterpieces.
The feds get interested in the Addams Family due to Pugsley's ham radio, powered by Uncle Fester, sending out mysterious "coded" messages world wide. Agent Hollister enlists the aid of a few private citizens to suss out the Addams domain without raising their suspicions, but it doesn't work. The Addamses become aware that something's not right and call in the feds.
Lurch's mother comes to visit the Addams family. Paralyzed by shame, Lurch is unable to admit to Gomez his mistake: Lurch has told his mother that he owns the big house. Gomez gamely suggests a role reversal: Lurch will act like the man of the house, and Gomez and Morticia will act as his servants. Once Lurch's mother arrives, Gomez senses his mistake. The old woman treats Gomez and Morticia poorly, and the husband and wife strongly wish they had never gone along with the act.
Lately, Uncle Fester's been a bit rundown, literally unable to maintain his wattage. Since Dr. Mbogo, the reliable family witch doctor, is too busy to leave Africa, the Addamses must take their chances by engaging the services of a local physician, who pays them a house call.
Parks Commissioner Fiske visits the Addams house seeking contributions for expansion of the city zoo. Gomez believes visiting Cousin Itt - all hairy and gibbering four feet tall of him - would be perfect as the zoo's new curator. He has the two meet, but Commissioner Fisk misunderstands the intent and mistakes Itt for a new exotic animal attraction whom he has hauled away in chains when the others aren't looking. When the family finds out what's happened, Uncle Fester is ready to administer retribution the Addams way - with a bullet from behind.
While Gomez and Morticia were away bat hunting, Mama resumed her old bad habit of fortune telling, which soon snags her an arrest on a municipal code violation. In her hour of need, the family rallies to her side as none other than Gomez "Loophole" Addams - who's never lost a case (nor won one either) - dusts off his law degree to defend her in court.
An accident with his new set of old Indian clubs gives Gomez amnesia and a complete shift in aesthetics. It, unfortunately, coincides with the new million dollar double indemnity insurance policy he's just drawn up to benefit Morticia, causing the amnesic Gomez - aghast at his macabre home and family - to think his life's in jeopardy. A second blow on the head might return him to normal. Unfortunately for Gomez there are plenty of clubs with just as many loving family members skulking about, keen to restore his sanity.
Once again, Fester's canon has wrecked the plumbing. The Arthur J. Henson Insurance Agency, subsidiary of Excelso Fidelity Insurance, is outraged by yet another in a series of payouts on the Addams policy, but a clause in the small print enables them to finally cancel it. Fester's allowance is subsequently suspended, so he gets a job - as an insurance salesman for Henson Insurance. It's not hard to guess to whom he sells his first policy, which has the head of the company in an uproar and storming his way to the Addams house to wheedle out of it.
Morticia and Fester overhear Gomez on the phone with his broker. Hearing the words "broke, penniless and wiped out," they believe Gomez is financially ruined, not realizing he's merely discussing the misfortunes of others before launching into a secret plan to buy his own railroad as a surprise to Morticia. Morticia rallies the rest of the family to figure out ways to earn money and help Gomez. Grandmama prepares to be a beauty stylist, Fester forms an escort service with Lurch, the children sell drinks at a sidewalk stand (henbane) while Morticia offers fencing and ...
Pugsley's late night missile launches cause no less than fourteen sighting calls to the Bureau of Mysterious Space Objects (M.S.O.). The Addamses are about to leave for a combined midnight picnic and snail hunt when they hear an announcement of unknown flying objects in their area. Thinking there might be Martians about, they happily decide to tarry and see while investigators from the M.S.O. converge upon the Addams estate with the same idea. The two parties meet, each deciding that the others are from another world.
Uncle Fester thinks his conjuring mishap has turned Pugsley into a chimpanzee. Now the family awaits him to turn Pugsley back into a boy, unaware that Fester's explosion merely knocked Pugsley into a secret room, where he's trapped, and that the chimp is just a chimp (escaped from an organ grinder) whom Pugsley befriended outside anyone's notice and dressed in a duplicate set of his clothes.
The city is planning to put a freeway through the Addams' neighborhood. In fact, the Addams' house is slated for demolition. Gomez and Morticia must find a solution, or else the house will be destroyed. Arthur J. Henson, city commissioner, visits to underscore the point: the Addams must move out. Unwilling to leave their precious home, Gomez and Morticia arrive at an idea: have the house moved to another location. Gomez buys the vacant lot next to Arthur Henson's home, and he pays to have their house moved there.
Uncle Fester confesses that he's exaggerated himself to his Illinois pen pal, Madelyn, especially about having a full head of hair - a mane to equal his bristling athleticism. For Madelyn's forthcoming visit, Morticia and Gomez have Uncle Fester outfitted with a hairpiece, but when Morticia learns that Madelyn has had five husbands, all now dead, she begins to worry for Uncle Fester's future happiness.
Morticia thinks marriage counseling would be the perfect career choice for Cousin Itt. To prove it to him, she and Gomez pretend to be a couple in trouble, but the pretense goes awry when she starts believing in parts of Gomez's fanciful play-acting. Now Morticia and Gomez really are a couple in trouble, and Itt won't do as a marriage councilor at all. Finally, a professional vocation advisor is called in to evaluate Itt, with an astonishing result.
Low grunts and grumbles while at the harpsichord constitute Lurch's manner of singing. Gomez has a record company record him and soon the Addams house is surrounded by excited teenyboppers, fawning and fainting over Lurch when he becomes the newest hit sensation. All that blind adoration goes to Lurch's head, and the Addames quickly find they have a self-centered butler who won't "buttle" any longer. Could it be they've created a monster?
A magazine article by eminent psychologist Dr. Francois Chalon has Uncle Fester believing that the happiness of Morticia and Gomez' marriage masks seething emotions buried deep, so Fester makes it his duty, for family peace and harmony, to get them fighting so they can let off emotional steam and become a truly happy couple. He recruits others in the family to this end but winds up with little to show for it. Finally, Fester calls in Dr. Chalon himself, but the eminent doctor proves to be a modern day Casanova, bringing different problems into the Addams home by ...
