Myra visits Steve at school for lunch, and once again accuses Laura of trying to vie for his affections. The end result is a huge food fight, which gets them into trouble since they receive cafeteria duty for two weeks and Myra is punished by her parents for two weeks. Steve decides to continue dating Myra, but he will break up with her if Laura changes her mind. Meanwhile, Carl – feeling he has lost his romantic touch with Harriette – decides to invest in a toupee. He later feels better when he learns that Harriette has also been dealing with hair problems as well.

Laura oversleeps on the morning of a huge cheerleader competition in Cincinnati, Ohio, and asks Steve to drive her there in his BMW Isetta. She quickly becomes frustrated with the car's slow speed, and in trying to get Steve to drive faster, causes it to break down. At the rundown hotel they stay at while the car is being repaired and a thunderstorm rages outside, Laura's disgusted and dismissive treatment of Steve finally pushes him to get angry at her and say he won't accept her treating him that badly anymore, which in turns leads Laura to apologize and the two of them to get back to being friends. Meanwhile, Carl gets annoyed as Fletcher and Estelle continually express love for each other in public, which is something he never does with Harriette. He also makes an inept attempt to fix the kitchen window after Steve broke it by jumping through it, against Harriette's admonition to call a professional.

Carl is trying to repair a lamp and ignores Steve's warning about bare wire touching the base of the lamp. Carl electrocutes himself, and only Steve knows CPR. Steve ends up saving Carl's life. The Winslows find themselves indebted to Steve and shower him with gratitude. The incident also inspires Eddie and Laura to learn CPR.

In the series' 100th episode, Harriette's employer, the Chicago Chronicle, is experiencing budget cuts, and Harriette's boss, Mr. Rollins, asks her to cut her workforce.

Meanwhile, Myra transfers to Steve's school and asks Eddie and Laura for advice in winning Steve's heart.

Weasel and Waldo entice Eddie into their football betting venture. A thug named Bones (Bubba Smith) pays him a visit when he loses a bundle, threatening him with serious injury if the debt is not settled in a timely manner. Refusing to listen to Steve's advice, Eddie sells Carl's precious stamp to settle the debt: a decision he will regret and wish Bones beat him up before his father finds out (which Carl does via Steve and the owner of the Stamp Emporium). Meanwhile, Laura adds a night job to her hectic schedule to try to get more money for a car, resulting in her being tired throughout the day. Soon Harriette convinces her to focus on her day job and let them come up with the other half of the money.

Harriette tries (a little too hard) to fit in with Laura's social group to bond with her daughter. Laura is embarrassed until KC and Maxine reminds her that their mothers aren't exactly close to them. Meanwhile, Waldo (who has been fired from a series of jobs) appears to be a failure at his new job as cashier at the Mighty Weenie until Eddie remembers that Waldo is a talented cook and rehires him as a chef.

When Eddie dumps Steve as his partner in a prestigious 2-on-2 basketball tournament in favor of a star player (Darius McCrary's real-life brother, Donovan McCrary as Kenny "The Spider" Jackson), the nerd turns to Grandmama (NBA star Larry Johnson's alter ego) for retribution. Meanwhile, Carl and Harriette quarrel over Laura's curfew. Laura sees this and decides to take responsibility for herself in the matter.

After Laura gets fed up with Steve's clumsiness and nerdy behavior after accidentally spilling drinks on her, she tells him that he needs to change. So Steve devises the ultimate scheme to win her heart...a potion called "cool genes" that will make him cool. Steve drinks the potion and becomes Stefan Urquelle, an ultra-suave, good-looking ladies man, and quickly wins Laura's heart and becomes popular with other girls as well. However, when his arrogant, narcissistic traits begin to show, it isn't long before Laura gets fed up and asks to have the irksome nerd back. When Stefan questions why, she admits as annoying as Steve is, he is more caring towards others, and Stefan complies by eating a tablet (serving as the antidote). Afterwards, Laura is happy to have Steve back and swears she never want to see the shallow Stefan again. Steve tells her that his cool alter-ego just needs to be renovated.

Laura wants to buy a car, but finds the high-pressure salesman (Stuart Pankin) more than she can handle alone, given his sexist attitude. At Steve's suggestion, she dons a mustache and hat and poses as a man to buy a car. Steve is close to spoiling Eddie's love life, especially when Eddie's previous and current girlfriends meet.

Laura, Steve and Waldo each have dates at the drive-in movie theater. Laura's boyfriend wants to have sex, but doesn't seem to understand the meaning of the word "no". Myra wants to have sex with Steve, but when he too refuses, she decides perhaps it is a good idea to wait. Waldo, of course, is Waldo, what with his bringing lawn chairs to enjoy the show, much to an embarrassed Maxine's chagrin. Meanwhile, Harriette starts charging Carl for services after they fight over a credit card reward. Soon Carl realizes his behavior is wrong, apologizes to Harriette and buys her a new refrigerator.

Carl and all of the car's passengers are ill-tempered, wanting to get home to celebrate the holidays with their families, leaving it up to Steve to remind them that Christmas can be celebrated anywhere with anyone.

Myra demands commitment from Steve or else. When he refuses and asks her to leave him alone by giving him space to decide, Myra leaves in a crying fit believing Steve wants her to go away. He must now turn to Laura for help in calming Myra down. Steve explains to Myra that while he had no intentions in breaking up with her, he also makes it clear that if they continue dating, she can't force him to commit to her right away and asks that she respects his decision when he asks her to give him space. Waldo constantly worries that other boys have their eyes on Maxine, causing him to go into a jealous fit. Meanwhile, Eddie learns that the store model he has a crush only dates guys her own age, like above 21 years old.

Meanwhile, Steve becomes depressed when no one seems to remember his birthday, unaware that Laura and Estelle are planning a surprise birthday party for him.

Wisecracker Jerry (Mark Adair-Rios) blabs about his latest conquest until Steve lets slip that Eddie has never had sex with anyone, leading to plenty of locker room teasing. He's embarrassed, until Laura reminds him that Jerry isn't popular with the girls and is the butt of their jokes. Eddie and his friends soon realize that still having your virginity as a teenager is just fine. Meanwhile, Steve seeks advice from Estelle when he needs her help in avoiding Myra, who wants Steve to commit to her.

Carl has warned Eddie about his late-night carousing before. So when Eddie is pulled over for a traffic violation, he says he was the victim of racial profiling by a pair of overzealous police. Carl refuses to accept his son's story of how he was "a black guy in a white neighborhood" until he sorts things out. What he finds out is the ugly truth (all as Eddie had explained) when the senior of the two officers reveals himself to be a severe bigot. An angry Carl threatens to report the senior officer for his racial profiling, while also urging his rookie partner to re-examine his own attitude. Meanwhile, Steve gets more than he bargained for when he takes a worried Richie to the dentist.

Accident-prone Steve is accused of blowing up the school's chemistry lab following an accident. With his academic future on the line, Laura defends Steve against his rival, Dexter Thornhill (Robert DeCrevel), who seems a little too eager to have him expelled. Catching on to his motivation early, Laura proves Steve's innocence by revealing who was really at fault with a blacklight. Exposed, Thornhill reveals he framed Steve for the crime, because he wanted to win last year's science fair and has hated him for always doing better than him academically. Steve's reputation is restored and Thornhill faces expulsion for his crimes.

To get him out of his hair for the evening, Carl sends Steve on a bowling date with Laura, then watches a movie. Estelle warns him that they may fall in love, but he ignores her and dozes off. Carl quickly has a nightmare about how Steve and Laura fell in love, got married and gave birth to a brood of Urkel-kids in the year 2009.

The next morning, Steve learns that Myra is going to a convent, causing the nerd to assume that she plans to join. He quickly enlists Eddie and Waldo to dress as nuns to find Myra and get her to reconsider her joining the nunnery. Of course, she had gone there to visit her aunt, but none of this comes out in the open until the guys are nearly arrested. Meanwhile, Carl becomes annoyed of Harriette's habit of leaving her wedding ring on the soapdish (located very close to the bathroom sink) when she puts on makeup.

Steve, still pining for Laura's heart, renovates his Stefan Urquelle alter ego by inventing a transformation chamber and a chemical to improve his boss sauce to allow him to maintain Steve's sensitivity towards others. He's a much friendlier person this time, but the formula soon wears off just as Laura professes her love for Stefan. Steve is resolved to one day make Stefan permanent.

Harriette asks Carl to go see an eye doctor after he complains about having problems seeing. However, he balks at the idea and takes Eddie's advice by asking Steve for some help. Steve, meanwhile, has been perfecting his machine to enable him to be Stefan all the time. Carl asks Stefan to let him step into the transformation chamber to fix his eyesight problems. However, a jealous Myra tampers with the machine by switching the dial thinking Stefan will use it to change back into Steve and ensnares him. Unbeknownst to her, Carl is really inside and once she learns the truth, she tells Stefan to stop the chamber. Sure enough, the chamber is broken and Myra realizes what she has done when Carl Urkel (instead of Carl Winslow) steps out!

Carl spends the next few days walking a mile in Steve's shoes, while Myra explains herself to Stefan. Eventually, Stefan (who has kept Steve's scientific genius, though at a slower rate) repairs the machine, and has him changed back before he can wreak any more havoc on the Winslow household. Carl and Stephen had a better understanding how these two put up with each other. Carl eventually realizes he could have spared everyone so much grief by following his wife's advice and getting glasses. Stefan realize this isn't the real him, it would be a boring world if everybody is the same and he rather be Steve Urkel.

However, he never turns his assignment in, thanks to a hungry Eddie and Steve, who quickly attempts to cover up the situation by baking the same cake for his mid-term (which is a lot harder than they expected since neither Eddie nor Steve have no experience in baking). Eventually, Waldo finds out and reprimands them for their greed. Meanwhile, Carl and Harriette invite Capt. Savage over to their house, but Savage's date Lois (Mariann Aalda) makes Carl suspicious about where he's seen her before and realizes she used to work at a local strip club when he was out on patrol interviewing a potential informant.

She points out that Eddie deserved to have the favor returned to him for his behavior. When Eddie tries to defend himself, she recalls two previous incidents that proves her point. The first time was when Eddie promised to go bowling with Carl, just to stand him up so the former can go out on his date with a girl from a college bookstore. She also recalls another incident with the car show in which he stood Carl up and never called him to cancel because he was out on a date (which she had found out about from Waldo).

Soon, Harriette tells her to drop the diet pills because she thinks the cheerleaders are just jealous of how great she looks.

Little does Eddie know is that he'll regret those words when he tries to have some alone time with Greta. When Carl gets the idea, he apologizes and Eddie decides to compromise in letting him come when he's not with Greta.

Carl fumes about not accepting a promotion five years ago that would have transferred him to Washington, D.C. While boarding a train to travel to the nation's capital for a seminar, luggage boy Steve accidentally stows away. The usual antics result, but the nerd helps Carl realize that "the road not taken" was perhaps the right decision after all. Meanwhile, Laura becomes suspicious about Maxine's new boyfriend D'Andre (Kristoff St. John), especially after he asks her to deliver a package for him and Eddie helps her prove it.

Myrtle, making her last push for Eddie, enlists Laura and Maxine to make her over head to toe. But Eddie, firmly in love with Greta, still is not impressed, so Myrtle decides to pursue someone else, which makes Eddie realize he'll somewhat miss her annoying attempts to win him, and asks her what is he supposed to do now that she's leaving for good. Myrtle replies with a famous movie quote from Gone with the Wind – "Frankly my dear, I don't give a damn". Meanwhile, Carl doesn't want Harriette to worry about his beautiful new masseuse, so he fibs about her appearance, claiming the masseuse is a "big, beefy sistea".

Carl tells a fellow police officer about the saga that led to Laura's engagement. Both Steve and Stefan propose to Laura. Her past adventures with both the nerd and the one-time "man of her dreams" are replayed through flashbacks (Steve in "Marriage 101," and Stefan in "We're Going to Disney World"). Laura is conflicted between the two, and when Steve feels Stefan is better, he plans to move to Russia to be with his parents, but Laura stops Steve when she realizes she couldn't live without him, and tearfully accepts his marriage proposal, saying that she is sure that he is the one for her, a promise which the two seal with a kiss.

After NASA buys the patent to one of Steve's inventions, he's sent into space with a pair of astronauts to test it out. However, Steve's invention unintentionally causes a nearby satellite to crash into the space shuttle, and before long he sends himself hurtling through outer space. Meanwhile, Harriette (worried for the well-being of rookie officer Eddie) demands to have him assigned to giving out tickets for parking meter violations. Myra attempts to use the media to pose as Steve's fiancée, but is caught by Stefan who finally forces her to relinquish her love for him.

In the series finale, NASA struggles to recover its astronauts and save Steve's life. However, all ends well, and Steve returns to Earth a national hero. Meanwhile, while on meter duty, Eddie finds himself in the middle of a shootout. Eddie survives thanks to the lucky bullet-proof vest that Carl gave him. During that time, Carl and Eddie help Harriette realize that the job is dangerous and she needs to support them no matter what. Steve sees Laura at the end of the episode and says "You get more beautiful every time I see you." Laura then says she will kiss him only on one condition, Steve will have to promise to "never go into outer space again." Steve replies with "Only when we kiss, Laura Lee, only when we kiss" and they do, much to the delight of the audience, who joyfully cheer in approval.
