Full House

After being insulted by a boy named Kenny, Michelle decides that she wants to be in the annual downhill soapbox derby championship, and she gets Becky to help her build a soapbox car. Michelle feels like dropping out of the race when she hears comments about how girls shouldn't be in the race. Becky talks Michelle into not quitting, and the elimination heats begin. In the final race, it's Michelle against Kenny, who has never lost a race -- and Kenny gets what he deserves when Michelle races past him and wins the championship. Meanwhile, Stephanie gives Joey ballet lessons as a way to help Joey improve his skills in ice hockey, and Joey ends up accidentally ripping the seat of his pants.
