A reprogrammed Urkelbot is sent to fight crime, and proves to be instrumental in foiling a serial convenience store robber. Meanwhile, the women find (to their horror) that a new shampoo has caused them to go bald.

Urkel and Carl are forced to share the same hospital room, when the nerd suffers from appendicitis and the cop wounded while trying to foil a robbery.

Urkel's trip to rouge dentist Dr. Smiley (to reassure a scared Richie) takes a back seat to a terrifying racial profiling incident involving Eddie. He comes home claiming that a traffic stop for a turn signal violation turned out to be much more when the officers accuse him of being "a black person in a white person's neighborhood." Carl is certain Eddie is trying to cover up for more late-night carousing, but when he gets the other side of the story from the officers involved, he learns the whole ugly incident exactly matches Eddie's side. Carl is very angry and, after telling the senior officer he will be reported, tells the younger officer to re-examine his attitudes. Carl then realizes he needs to apologize to Eddie.

Carl is assigned to guide Richie's class on a tour of the police station. The tour isn't going so well, until a robbery suspect gets free and holds one of the children hostage. Carl makes good on his opportunity to diffuse the situation, and impresses the youngsters. Meanwhile, Myra thinks Urkel and Laura are sneaking around together when they keep mum about their whereabouts ... only to learn they were planning a surprise party for her birthday.

Steve and Stefan arm themselves with roses and rings as they both decide to propose to Laura. Stefan is Carl's choice because he wants Steve to return to his perfect ex-girlfriend, Myra Monkhouse, and marry her instead. Laura struggles with her choice because no matter what happens, her decision will cost her one of the guys. Harriette tells her that no matter what decision she makes, they'll support her. Steve announces that he's not going to propose to her and decides to go live in Russia with his parents. Laura decides that it is him she wants to marry, not Stefan. Steve has been a gentleman to her ever since they met and she deserves that over having a glamorous and shallow life. Carl is not happy with her decision, but he also realizes that it was hers to make.
