Ren is lobbying to get her own telephone. Her parents say she can have it if she keeps from insulting Louis for a week. At school, sleazy salesman Mr. Wallace promotes the 7th grade chocolate sale, offering a state-of-the-art motor scooter as a prize for the most sales. Louis catches scooter fever and makes plans with Twitty to sell 400 boxes of chocolate. By mistake Louis and Twitty both order 400 boxes, and Mr. Wallace tells them they're financially responsible for all of them. Twitty and Louis fight about who's to blame and break up their partnership.

The next day Louis gets up early to start selling the chocolate, but his sales technique is lousy compared to Twitty, who even sold Mrs. Stevens six bars. Back at home Donny has used so much hot water in the shower that all the stored chocolate in the garage has melted and is sliding down the driveway. Mr. Stevens slips and falls in it, as does Wallace when he comes by demanding payment. Mr. Stevens tells him off and threatens to sue

Louis is managing Twitty's band. They've got a chance for a gig at a big party thrown by Jason Bagwell, so they are auditioning for a lead singer. Ren hates the band until she gets a look at Jason, then she decides she wants to be the singer in order to go to the party. Louis says no way, but the band likes her much better than the parade of freaks they've been auditioning. Fearing Ren will take over, Louis puts Ren's membership to a vote. The band all vote for Ren and against Louis. Frustrated, Louis gets Tom to program a few instuments and he forms a rival techno band featuring the bizarre poetry of Tawny. Both bands audition before Jason. He rejects them both, but proves himself to be such a jerk that no one wants to get the job anyway. The two groups form a ""super band"" and play their own big gig--at a kids' birthday party.

Louis is being threatened by Lloyd, a bully at his school. Tom tells Louis that he needs to stand up to Lloyd, but Louis dismisses Tom's advice, inferring that he's a wimp who doesn't know what he's talking about. But Louis isn't handling Lloyd very well, and in shop class Lloyd humiliates Louis by putting the smaller guy into a hutch (cabinet) that he's building. Tom decides he's seen enough. As calm as Clint Eastwood, he strolls up to Lloyd and tells him to stop. Then he surprises everyone by putting on a dazzling display of karate moves, breaking boards and other pieces of wood left and right! Lloyd immediately backs down.

In an instant, Tom changes in the eyes of Louis from a wimp to a hero. He tells Tom he wants to be his student and learn his ways. But before his first lesson, Louis impulsively calls up Lloyd and invites him to meet in an alley for a showdown. Tom then tells him it will take Louis nine years to learn his teachings! Louis learns all he can in one day, then goes to
