Dick receives an unpleasant order from the home planet on the hour-long third-season opener: he must marry the Big Giant Head's niece Janet. As Sally, Harry and Tommy escort Janet on the rocket to Earth, the bride-to-be sets out to prove that she's a true domestic goddess, brushing up on her skills by reading The Joy of Cooking, The Joy of Sex - and The Joy of Yiddish. But a defiant Dick is sticking by Mary; whether Mary will stick by Dick is another question. Meanwhile, Janet's arrival in Rutherford is anything but quiet: Officer Don suspects that aliens have landed.

But a defiant Dick is sticking by Mary; whether Mary will stick by Dick is another question. Meanwhile, Janet's arrival in Rutherford is anything but quiet: Officer Don suspects that aliens have landed.

Dick and Mary take out their frustrations about their broken engagement on each other and begin an elaborate game of practical-joke one-upmanship, while Sally eyes her disinterested yoga instructor and Tommy reluctantly joins a garage band, with Harry as his roadie

Dick inadvertently lets a huge skeleton out of Mary's parents' closet when he accompanies her on a trip to see her folks, while Sally adjusts to new closet space when she temporarily moves in with Nina.

Dick turns out to be a scaredy cat when faced with the prospect of a physical exam. Meanwhile, Sally and Tommy house-sit at Albright's house on Halloween night - that's bad news for neighborhood trick-or-treaters - and Harry stays home alone, except for some very weird noises coming from the basement.

Dick is forced to diet when he discovers he's put on an enormous amount of weight.

Dick longs for the chance to administer his "unique brand of jurisprudence" when he's called for jury duty; Sally falls for an "artist" [ to Officer Don's chagrin ]; and Tommy and Harry help Albright with a "preverbal" project [ they must remain mute for five days ].

Dick, friendless after his breakup with Albright, tries to shoehorn Officer Don into his life as best friend and constant companion... with mixed results. Sally shanghais the slickly popular dancer Peter Connelly ("King of the Jig") to Johnny Foam's Cafe as a sacrificial lamb for her moody artist boyfriend Seth, and is horrified to learn that rather than the dark and tortured soul the fell for, Seth is a poseur... and a jig fan. Harry tries to get a job so he can buy Tommy some roller blades, but lacking the required diploma, he must first weather the indignities of night school.

The Solomons reflect on their sinful ways in an episode that illustrates their misdeeds in clips from past episodes.

Tommy tells Dick he'd really like to meet a woman closer to his real age, say someone like Angie Dickinson. Sally says it's time for her to go out and look for a real job. Dick thinks Harry's watching far too much television and orders him to give it up for a week. Tommy goes to Mary's to return her magnifying glass that Dick has broken, and Mary observes how immature Dick is. They start talking and are immediately engrossed in a discussion about the Aztecs. Their mutual attraction is obvious. Sally is hired as an assistant by Webber, a man who's very impressed by her appearance and couldn't care less about her lack of typing skills. Dick is wild with curiosity when Mary has a lunch date with a mystery man named Tom. August tries to resume her relationship with Tommy, but he tells her he's seeing someone.

Dick thinks he's doing the right thing when he offers to personally rehabilitate a criminal, but winds up doing more harm than good; Sally tries to help Mary find a new home for Pepper; and Harry struggles to complete a book report on Little Women.

Dick hurts himself playing in a wheelchair, which puts him in one for real - and turns him into an angry advocate for handicapped rights. Meanwhile, Dubcek's daughter Vicki visits but decides to become celibate, much to Harry's chagrin.

Dick decides that it's time to date again, so he goes to Sally and Officer Don for advice; Harry and Tommy find a wallet with 0 in it, and return the money to the owner.

Venusians disguised as gorgeous babes plot to plunder Earth of its riches in an uproarious episode that climaxes at Super Bowl XXXII in San Diego. When hordes of beautiful women start showing up in sleepy Rutherford, Ohio - and seem enthusiastic about dating average Joes like Dick, Harry, Tommy, and Officer Don - Sally suspects that something's amiss. Before she can warn anyone that the women are really Venusians bent on dominating Earth, they discover her and force her to become one of them. The Solomon men embark on a country-wide search for Sally that ends at the Super Bowl, where the lethal lovelies have planned to unleash their most devastating weapon yet - the ultimate beer commercial, designed to enslave mankind into coughing up the rest of their pricey consumer goods. In the supervixens' lair, the Solomon men seem defeated, but with the help of Sally, who only pretended to turn against them, and Venusian Mascha [ Cindy Crawford ], who's been won over by Harry's simple charms,

Harry's pet follows him to Earth - in human form; Sally visits her first gynecologist and decides to pretend she is pregnant.

Dick has casual sex with a woman he meets in line at the movies, then doesn't understand why Dr. Albright gets upset when he keeps talking about the encounter. Dick learns that the woman is the mother of one of his students, Bug, whose father and brothers pay a visit to Dick in an effort to teach him to show a little more respect. Sally decides she needs her own car, and she, Harry, and Tommy learn about the joys of shopping at a used car lot, where they learn that the salesman is decidedly not a "friend who's there to help".

Tommy, tired of having to handle all of the "kid" duties [when in reality he's the oldest member of the mission], decides to retire. After he spends some time at a retirement home, he changes his mind, realizing that a big part of what makes you old is acting - and being treated - like your old. Dick, thinking that Mary is anguished because she never got a chance to fulfill her fantasy of becoming a torch singer, tries to help her to realize that dream. He learns that sometimes the choices we make between two career paths can be right on the money. In a moment of weakness, Officer Don steals a pair of Sally's panties, and makes a series of vain attempts to return them without being caught in the act.

Dick wants to get back together with Mary, so he's in luck when they find themselves locked in the school library overnight. Meanwhile, Sally, Harry and Tommy search for Dick. Their first (and only) stop: Mary's house.

Albright's father walks out on his wife and into Sally's life, while Harry walks into Rutherford College's vacant radio studio and begins his career as a shock jock.

Dick demands that Sally and Harry go to work, so she signs on as Albright's research assistant and he gets a job tending bar. Then Dick decides on a career change for himself (he wants to be a cop) after a disastrous Career Day at Tommy's school.

John Cleese puts his zaniness to good use in a two-part guest shot as a new professor who's even nuttier than Dick. And smarter. He's hotshot Dr. Liam Neesam, and he's a little too good at everything he does. He makes his first appearance in Part 1, as Albright (Curtin) is getting fed up with the fact that Dick - and the rest of the Solomons, for that matter - are "weird". "It's like being around the Addams Family", she moans. So Dick sets out to make his brood "average", and succeeds so completely that Albright finds him boring. Enter the off-kilter Dr. Neesam, who she thinks is kind of charming.

Dick has a rival for the title of Pendelton's nuttiest professor - and a rival for Albright's affections - with the arrival of the mysterious Dr. Liam Neesam. Meanwhile, Sally feels that she's losing her touch with men after Don seems to lose interest in her.

Sally turns to romance novels for inspiration when it's time for her first kiss with Officer Don. Unfortunately, whether they try it on a windy, moonlit bluff or in the Solomons' kitchen, the kiss just isn't special enough. Sally becomes resigned to breaking up with Don, but when she goes to the police stable to tell him, the magical combination of horses, thunder, lightning, and Don's newfound forcefulness combine to make Sally realize Don's the guy for her after all. Dick is perturbed because Lucy the cafeteria lady charges him - and only him - for crackers. Realizing he has no control over her inexplicable dislike for him allows him to free himself from being bothered by her unjust treatment. Harry graduates from night school, and he and fellow classmates Mrs. DeGuzman and Larry reminisce about all the great times they had together during their ten-week enrollment.

Dick takes the family camping as a mission bonding activity. At the campsite, the family and Mary all become angry with Dick - the family because he lies about bringing Mary along after he tells them it's "family only", and Mary because he tells her the family doesn't mind she's coming along. After they all cast him out, Dick goes off by himself and attempts to form a new society with a troop of Beaver Scouts he encounters. The Solomons assume Dick is lost and set out to find him. They (especially Sally, who resents her command being usurped) initially reject Mary's offers of help in finding Dick... until they realize she knows a lot more about the outdoors than they do.

Mary is asked to appear in a new Pendelton University promotional video. Dick whines until he is also allowed to participate. Unfortunately, neither of them shares the director's vision of what their "performances" should be like, and they are unceremoniously replaced by other "actors" (including Tommy). Harry volunteers to drive Nina to the dentist. A romance develops, but fizzles when the money Harry leaves under Nina's pillow as a Tooth Fairy reward is misinterpreted, and Nina, highly offended, throws him out. Officer Don gives Sally a key to his apartment, but his glee soon turns to gloom when she starts seeing the place as less of a love nest and more of a one-woman party zone that she can trash whenever she wants to. When Don calls her attention to her inconsiderate behavior, she apologizes - but he still takes back his key.

The Solomons wind up their third season - and perhaps their mission on Earth - with a romantic dinner party that turns predictably raucous. The chef is Tommy, who has just "come out" as a gourmet. The guests: Dick and Mary, Don and Sally and Harry and Mrs. Dubcek's amorous daughter Vicki, who is back in his life. The trouble is, Vicki's jealous ex-boyfriend is hot on her trail. He's also hot to "put a hurt" on the competition and kidnaps Harry just before he transmits a message from the Big Giant Head. The other Solomons miss the communique, which promises devastating consequences for the family.
