 School bully Willie Fuffner has his eye on Laura, who wants nothing to do with the guy that is intimidating others, including Greg, the guy Laura really wants - to the dating sidelines. Urkel tries to stick up for Laura, but Willie takes sadistic pleasure in beating back the nerd. The two get into a fight at school and the gym teacher decides that - instead of referring them to the principal - they should fight it out in the boxing ring! Carl gives Urkel a few pointers, but gets plenty of black eyes instead. On fight day, Urkel holds his own ... temporarily. Just when Fuffner is about to deliver the knockout punch, Greg challenges the bully to a fight. Fuffner accepts, but then other boys decide to fight back and eventually outnumber the bully, who decides to run.
