Willie Fuffner wants to ask Laura out, but she wants no part of him. He's threatened to beat up anyone who gets in his way, including Urkel (especially Urkel) and another nice young boy named Greg who has a crush on Laura, but has no idea how to advance to first base.
Meanwhile, Willie and dim-witted sidekick Waldo break into Urkel's locker to trash it. Urkel confronts the two about violating his property and treating Laura disrespectfully. Urkel and Willie get into a big fight at school, and it isn't long before Coach Redding breaks it up.
Instead of taking the sensible route and making the two apologize, he makes an appointment for the two to meet in the boxing ring!
Carl spends part of the episode giving Urkel a few pointers, but the results are what you'd expect.
Come Saturday morning, Urkel and Willie meet in the ring. If Urkel wins, Willie must leave everyone alone, but if Willie wins, he gets the hand of Laura.
Of course, Willie quickly gains the upper hand, and it isn't long before he has the nerd seeing visions of multiple Lauras! Shortly thereafter, Laura declares she's seen enough and tells Willie what she thinks of him.
Eddie then stands up and offers to fight Willie after he gets finished with Urkel. Willie accepts the invitation, and takes Greg up on a subsequent offer after Eddie gets laid out. But then many boys offer to fight Willie, and after deciding he's finally overmatched, the bully's feet gives way to fear and runs out, Waldo scurrying close behind.
The winner and still champion: Urkel!
