"3-2-1, 1-2-3, what the heck is bothering me?" That's the advice Carl decides to heed as he tries to deal with stress-related high blood pressure. But will the tip work when Urkel - who shows off his new BMW Isetta to the Winslows - asks the cop to help him learn to drive?
Rumors fly around school that Laura and Ted had sex on their date. Urkel confronts Ted and his buddies, but gets shoved into his locker, then Laura refuses to believe the nerd when he warns her about the rumors. When Maxine's story about the rumors match Urkel's, Laura decides she needs to salvage her new "easy" reputation and get the truth out in the open.
Eddie is told to take Richie trick-or-treating, but it interferes with a hot date. Richie decides to go alone and gets lost. When Eddie finds out, he goes on a frantic search to find the little tyke before everyone else finds out.
Waldo's fragile self-esteem takes a huge hit when a misunderstanding he caused results in Eddie's girlfriend leaving him. Waldo decides the only way he can cope is to join the Army Reserves. Urkel finds out and insists that Eddie go look for him and apologize before Waldo makes a big mistake. Of course, Urkel, Eddie and Waldo wind up causing a whole lot of hijinks and get on the wrong side of a tough drill sergeant before they can talk things out. Meanwhile, Carl and Harriette deal with a shady repairman.
Just as Richie is trying to deal with pushy 5-year-old vixen Gwendolyn, a determined Urkel pulls his biggest stunt yet in trying to get Laura to go out with him - by sitting on the roof of the Winslows' house and not coming down until she says yes.
Eddie becomes fed up with Carl's strict house rules, and he's not going to take it anymore. Urkel becomes frustrated when his parents make him cease with the scientific experiments (which always cause trouble), and he's not going to take it anymore. The solution? Pool their funds and become roommates in a run-down South Side apartment.
The two types of bonding take center stage. In the literal sense, Laura is trying to get back together with class hunk Ted Curran, but when Urkel tries out his new super glue (to repair Laura's broken earring), he accidentally gets his hand stuck on Laura's shoulder ... just as Ted shows up! In the relationship sense, Carl buys a used police car at auction, hoping a restoration project will be the key to bonding with Eddie. But Eddie wants his project partner to be Waldo instead, causing Harriette to set her son straight.
A slick-talking college recruiter tries to woo Eddie to his college for his basketball skills (and certainly not his meager academic credentials). Harriette is skeptical about the college's academic program and gets a former college basketball player - who eventually flunked out of school where Eddie wants to go after he got injured - to help set an impressionable Eddie straight. Meanwhile, a sleep-famished Laura is determined to study for her SATs and get into Harvard Law School, so she gets Urkel to stand in for her while she sneaks off to the library. Laura ...
When Ted and Laura become tired of Urkel interfering in their relationship, they decide to set him up with a girlfriend of his own - the beautiful Myra Monkhouse. The foursome head off to a Dave Koz concert, where Urkel enlists the jazz saxophonist to help him redouble his resolve to win Laura's heart. Meanwhile, usher Waldo tries to sort out in his mind what various female celebrities new names would be if they were to remarry!
Eddie, Waldo and Weasel plot to sneak into the hotel room of rhythm-and-blues singer Tracie Spencer to procure tickets for her sold-out concert. Meanwhile, Carl recruits Urkel to read Harriette's diary after he becomes suspicious that she has feelings for another man.
After Eddie causes a classroom prank that could get him thrown off the basketball team, he gives a sob story to his teacher, claiming he has a bad home life. The teacher pours her sorrows out on Urkel and suggests that she pay this family a visit, unaware it is the Winslows. What she sees is a highly chaotic household, particularly since Harriette (in the subplot) had gone on strike! However, Eddie has a lot of explaining to do when the truth comes out.
Eddie becomes despondent when he learns that Oneshia is two-timing him. At a high-rise party, he goes onto the fire escape to sort his emotions out ... and considers suicide. Urkel and Waldo, concerned for their friend, try to talk Eddie down, but all three of their lives are soon endangered when the fire escape begins to give way. Meanwhile, Fletcher Thomas proposes to Estelle, and her answer upsets Carl.
Carl and Fletcher quarrel over the wedding arrangements. Carl wants a big bash for his mother and future step-father, but he and Estelle wants a quiet wedding with just their closest friends and family. He may unwittingly get his wish, particularly after Waldo screws up on the invitations to Eddie's house party (on a separate weekend when the folks were to be out of town). He even goes as far as grounding Eddie for his plans to have a party.
Laura is desperately looking to shed her "nice girl" image, so she and Maxine obtain fake IDs and go to a male strip club for a wild evening on the town. Problem is, Harriette, Rachel and Estelle are there too (having their own "evening out") ... and Urkel, who gets wind of Laura's plans and in trying to stop her, accidentally performs onstage.
Myra's looking for some "Hot Stuff" - namely, Urkel - and asks Laura for advice on breaking the ice with the reluctant nerd. Meanwhile, Waldo sells Eddie a discounted car stereo that literally may be "hot stuff."
Urkel surprises his fellow prom-goers when he walks in with beautiful Myra. Meanwhile, Laura's prom date turns out to be a possessive creep who demands that she dump Urkel as a friend, and threatens her if she doesn't comply.
When Urkel decides to at least try to have a relationship with Myra, she sees Laura as competition and tells her to bug off. Meanwhile, Eddie is promoted to manager at the Mighty Weenie, and one of the employees under his watch is Carl.
