After failing a magazine test on being a good father, Homer decides to help Bart out with his Soapbox Derby race car -- and soon is left out when Martin gives Bart his race car (after crashing into a wall and getting sent to the hospital) so he can win against Nelson Muntz. Meanwhile, Patty and Selma get their hair styled like MaryTylerMoore.

!!This episode has the following tropes:
* GracefulLoser: Nelson once Bart beats him in the finals of the Soapbox Derby races.
* LikeFatherLikeSon: Dave and Dave, Jr. at the National Fatherhood Institute. Also, when Bart ridicules Nelson for losing the race, Homer gladly joins in.
* ManOnFire: The Honor Roller's crash leaves Martin on fire. Firefighters focus on the crash site, while Martin runs around screaming.
* OhCrap: Dave's reaction when Homer calls the National Fatherhood Institute and says he got a zero on their test.
* {{Retirony}}: Parodied in the [=McBain=] clip.
* ReversePsychology: Homer's brain uses it to convince him to use it to convince Bart to let him help with the Soapbox Derby race car.
* SkywardScream: Arguably the show's most famous example:
** "Martin. I'll curse that boy til the day I die!"
* SoProudOfYou: Homer responds to Bart's mockery of Nelson with "That's my boy!"
* StylisticSuck: Little Lightning.
* TakeThat: Creator/BillCosby is treated kindly by the episode, though one piece of a dialogue was written as a knock on his criticism of the show.
-->'''Homer:''' God bless you, Bill Cosby! You've ''saved'' the Simpsons!
* ThreateningShark: While Homer's at the National Fatherhood Institute, a shark somehow gets into a tank and attacks a father and son in the middle of an underwater activity.
-->'''Dave:''' [[OhNoNotAgain Oh, dear God, not again!]]
* WhatCouldHaveBeen: Homer was originally gonna say "I'm not the bad father, you're the bad father. Leave me alone."
* WhatTheHellHero: Marge calls Homer a bad father when he refuses to go to the big race.
