Saturdays of Thunder

Season 3, Episode 44

Bart becomes deeply immersed in competitive soapbox racing while Homer begins to realize that he is not as good a father as he thought. After attending a lecture at the National Fatherhood Institute, Homer becomes a more attentive father, helping Bart build the ultimate soapbox racer. But Bart chooses not to use it in his big race against Nelson, instead opting to borrow Martin's scientifically engineered aerodynamic racer.
