In this BizarroEpisode, Homer and Bart adopt a horse (again) and train it to be a badass on the racetrack, which irks a secret society of jockey elves. Meanwhile, Lisa files a complaint to President UsefulNotes/BillClinton over an unfair judgment at the county fair's Battle of the Bands.
* AsHimself: South African horse racing announcer Trevor Denman, who wasn't credited for his appearance, is the announcer for all of Duncan's/Furious D's races. He even uses his real-life CatchPhrase - "''AND AAAAAAAWAY THEY GO!''" - at the start of each race.
* AudienceSurrogate: The Comic Book Guy becomes one in this episode, pointing out that it recycles old plots and character traits (such as the Simpsons having a horse and Marge's gambling).
* BaitAndSwitch: "That horse better win, or we're taking a trip to the glue factory... and he won't get to come!"
* CheatersNeverProsper: Double Subverted. The Ogdenville band cheats by using visual aids, then is stripped of their win by the President.
** Subverted by Furious D; he bumps his fellow horses out of the way like he's in a NASCAR race, and is never disqualified.
-->'''Nelson:''' Oh, man, that horse don't take no guff from nobody.
-->'''Nelson:''' I mean sh— (''Jimbo and Keaney pummel him.'')
** When the Simpsons are mulling over taking Duncan in or not:
--->'''Marge:''' Hmmm. Should the Simpsons get a horse?
--->'''Comic Book Guy:''' Excuse me, I believe [[Recap/TheSimpsonsS3E8LisasPony this family already had a horse]], and the expense forced Homer to work at the Kwik-E-Mart, with [[HilarityEnsues hilarious consequences]].
--->'''Homer:''' (''pause'') Anybody care what this guy thinks?
--->'''Marge:''' Okay, Lisa, I've got Furious D across the board, boxed with the three and the eight and wheeled up and down.
--->'''Lisa:''' Mom, I think you might be [[Recap/TheSimpsonsS5E10Springfield developing a gambling problem]].
--->'''Comic Book Guy:''' ''(while wearing a "Worst Episode Ever" t-shirt)'' Hey, I'm watching you.
* EveryoneChasingYou: Jockey-sized trolls chase after Homer after Homer breaks his promise to throw the horse race so they can win.
* HeartBeatsOutOfChest: Parodied and deconstructed. Moe meets a beautiful woman at a horse racing track, and his heart starts beating out of his chest like in the older, wackier [[UsefulNotes/TheGoldenAgeOfAnimation Golden Age of Animation]] cartoons (particularly the ''WesternAnimation/LooneyTunes'' and [[WesternAnimation/TexAveryMGMCartoons MGM]] cartoons directed by Creator/TexAvery). When he notices this, he identifies this as the symptom of a serious medical problem, and says he has to leave for the hospital.
* JerkassHasAPoint: Lisa is right that the Ogdenville band cheated, though few appear to care.
* SoreLoser: Lisa.
* SpoofAesop: UsefulNotes/BillClinton says that if you don't win something, complain until you get it. Marge even points out that that's a lousy lesson...
* TakeThat: ...which Clinton counters by stating he's a lousy president.
* TakeThatAudience: "Anybody care what this guy thinks?"
* ThatWasNotADream: After the scene in Jockey Town, Homer is sent back to the surface.
-->'''Homer:''' Did that really happen, or was it all just a wonderful dream?\\
'''Jockey:''' ''[popping up]'' No dream. Lose the race, fat boy.
* WorstWhateverEver: Comic Book Guy criticizes the episode, which recycles old plots and character traits ("Excuse me, I believe this family already had a horse", Marge's gambling). As the episode proceeds, he wears a "Worst Episode Ever" shirt. When the credits end at the Gracie Films production logo, he says, "Worst. Episode. Ever."
