The Solomons are relieved when Vicki's baby turns out to be human, but horrified when she announces her plans to sell her story to the papers. When a reporter comes sniffing around, Sally gives Dick the title of Security Officer and orders him to kill him; however he can't, so she makes him High Commander and herself Security Officer so that she can kill the reporter herself.

When a drunk Mary tells Dick she once had a fling with his archenemy Vincent Strudwick, he is outraged and decides to get even with the pair of them by convincing Strudwick's wife to sleep with him.

When Mary and Nina talk about how good looking Harrison Ford is, Dick decides that he himself is hideous and visits a plastic surgeon to discuss having his face surgically altered.

Harry, meanwhile, is chuffed when the surgeon tells him that his face is perfect.

Dick is confused when Nina won't let him accompany her to her Black Student Union meeting, believing it to be a Weight Watchers type club; so, in an attempt to understand the concept, he mistakenly takes the Solomons to a racist white power rally. Dick realizes that the rally was a bad idea, and tries to make it up to Nina by firing her, to release her from what he calls her 'servile role' (as he and Mary's assistant), but she informs him that she is happy in her job. Meanwhile, Sally, Harry and Tommy are preparing to take part in a poetry competition and decide to use racism as their subject.

Mary is horrified when she learns that Dick has been pocketing all the tip money she has left at restaurants, but Dick is baffled by the concept of tipping, and attempts to re-invent it by placing a stack of one dollar bills on the table and informing the waitress that when she pleases him, the pile will grow, and when not, it will shrink.

Mary is tired of spending all of her time with Dick's family and so suggests that the pair befriend another couple - her tennis partner Gwen and her husband Larry.

Meanwhile, Sally, Harry and Tommy are forced to use the laundromat when their washing machine breaks down, and immediately fall in love with the place, even setting up a laundromat court, in which Sally, imitating several of the phrases and mannerisms of Judge Judy, settles squabbles over people's washing.

Jealousy arises, however, when Tommy discovers that Sally saw Alissa naked in the changing room, and then Sally discovers that Alissa accidentally walked in on Don changing in the Solomons' toilet. After Dick (and Nina) win the dance competition, the episode closes with a wordless pas de deux, complete with orchestral accompaniment of George Gershwin's "He Loves and She Loves", in a tribute to the final scene of the 1957 film Funny Face starring Fred Astaire and Audrey Hepburn. A portion of the film's choreography is re-created by Dick and Mary.

As his overlord becomes increasingly more clingy, Dick begins to wonder what the reason behind it is. Meanwhile, Sally gets the wrong idea when she hears Alissa giving Tommy advice about his Valedictorian speech, and saying that it is a time to move on, and so, thinking that Tommy is about to get dumped, she finds Alissa and breaks up with her on his behalf.

Harry and Tommy try to raise their own funds by setting up a lemonade stand.

An invitation arrives in the mail from an 'Aunt Florence', inviting 'Richard Solomon' to attend a Solomon family reunion in Indiana. This is obviously a mistake, so Dick phones Florence to set the record straight. Upon discovering that Richard is so estranged that his family wouldn't recognize him anyway, he decides that the aliens could do with some roots and accepts the invitation. Upon arriving, however, it becomes clear that the only reason the real Richard is estranged is because of an old family fallout - and it hasn't burned out yet.

When Harry's boss Doug starts deducting income tax from Harry's paycheck, the Solomons realize that they have never filed a tax return and that they owe $9500 to the government. To combat this, they invent the 'brilliant' notion of lying on their tax return and Dick reworks the sums so that the government owes them several hundred thousand dollars.

Meanwhile, Tommy deliberately lands himself in detention with his dream girl Alissa, so that he has a chance ask her out.

When a meeting is rescheduled without her having been notified, Mary begins to have doubts about the longevity of her position as Dean, and Dick leads her to become paranoid that there is a conspiracy to have her removed from her job. The pair decide to investigate, and end up breaking into Judith's office by night for evidence, only to be caught by the police. Vicki Dubcek decides that the best thing Sally needs to help her get over her break up with Don is a weekend of riverboat gambling on the Cincinnati Queen, a floating casino - where Harry manages to win big, while Sally gets her lips on a Neil Diamond impersonator.

Dick begins to feel that the unit is falling apart when Sally announces her plans to move out, and he tries in vain to clip her wings.

Meanwhile, Tommy sees babysitting with Alissa as an opportunity to prove to a dubious Harry that she really is his girlfriend.

Sally, however, is less than happy. Mary suggests that she and Dick go on a couples retreat so that they can work on their communication skills. Despite her good intentions, everybody, including Harry and Vicki, embraces Dick's openness and criticizes her for pointing the finger.

Charlotte first claims to be auditing his class, then later claims to be a reporter, then an intellectual groupie. She and her son wangle her way into his birthday plans, cancel his party and lock the guests that do arrive in the basement.

Meanwhile, Tommy decides to waste no more time in his life - and asks Alissa to marry him.

The Big Giant Head sends a message that he intends to visit Earth, so Dick quickly orders Sally to move back in and Harry to stop attempting to make a baby with Vicki. He then attempts to prepare Mary for his visit by telling her that an 'old college chum' is visiting and that she would be well advised to discuss how much he has learned in bed. Harry tries his best to avoid Vicki, but eventually resorts to telling her that he can't father a child with her right now.

Harry, Sally and Tommy return to Earth, but are forced to bring along the Big Giant Head's niece, who is assigned to act as Dick's wife in order to keep his focus on the mission and off Mary.
