Recap / The Simpsons S 12 E 9 HOMR
After losing the family's life savings in the stock market, Homer gets a job as a test subject for scientific experiments, one of which reveals the true reason behind his stupidity: a crayon that got stuck in his brain when he was a child. When Homer gets the crayon surgically removed, he becomes a more intelligent man — and soon learns that being smart doesn't equal being happy.

This episode contains examples of:

  • Affectionate Parody: Of Flowers for Algernon.
  • Artistic License: Homer's so-called proof that God doesn't exist dips into Artistic License Physics and Artistic License Religion. Ignoring the possible Unfortunate Implications/Author Tract behind it, God is not a number or a quantifiable figure (since Homer was talking to Ned Flanders we can assume Homer's referring to God as understood by Christians), so equations cannot be evidence against Him.
  • Back-Alley Doctor: Moe, though he operates in his bar rather than a back alley. He even has cards of his shady business.
  • Belief Makes You Stupid/Take That!: Savagely invoked Homer uses his new found high I.Q. (which is actually 105, only slightly above average), among other things, to scientifically prove why God couldn't possibly exist. Flanders is, of course, angry, but after reading Homer's text through he quickly concludes he's absolutely correct. Instead of just accepting the other viewpoint Flanders then decides that he must prevent the others from ever seeing the document, though Homer is already putting it underneath every car's windshield wiper.
  • Biting-the-Hand Humor: When Homer checks his stock numbers for Animotion, he shouts, "Yahoo!" which translates to "Yahoo!" (the website), and then says, "Huh? What is this crap?" which translates to FOX Broadcasting. Cue Homer smiling when he finds out their stocks are down by 8 points.
  • Call Back:
    • Ozmodiar, the space alien from The Simpsons Spin Off Showcase briefly appears twice during this episode, once after Bart says cartoons do not have to make sense, and once more after all the employees are laid off from the plant.
    • A more subtle example can be seen in the Classic Cartoon Commercials booth, which is adorned by the artwork of Flatulent Fox, Brown-Nose Bear, Dinner Dog, Rich Uncle Skeleton, and Disgruntled Goat as seen in the episode "The Day the Violence Died".
  • Crapsack World: Homer seems like a super-genius with the crayon removed from his brain. However, he later states his new IQ is 105, which is only slightly above average. The people of Springfield are just that stupid (including the ones said to be smart, like Lisa, Martin Prince [whose I.Q. is 216], and the members of MENSA on "They Saved Lisa's Brain" who's IQ's range from 150 - 190 before Lisa joins note ).
  • Crossover Punchline: Philip J. Fry appears briefly during the Couch Gag.
  • Failed a Spot Check: When Homer asks why the crayon in his brain wasn't detected earlier, Dr. Hibbert appears to explain that it was always hidden by his finger whenever he held up the X-ray.
  • "Flowers for Algernon" Syndrome: Homer experiences this.
  • Intelligence Equals Isolation: According to Lisa, as intelligence goes up, happiness often goes down. She even made a graph of it.
  • Is This Thing Still On?: After Homer demonstrates new animation techniques while wearing a Motion Capture suit, he goes into the men's room to relieve himself, while the audience can still hear and see everything he does. They cheer him on when he announces that the urinal cake has eroded away.
  • Mix-and-Match Critter: The octoparrot, which Homer holds up as proof that the scientists are Playing God.
    Octoparrot: Awk! Polly shouldn't be!
  • Nose Shove: How the crayon ended up in Homer's brain.
  • Take Our Word for It: Homer's proof that there is no God. It even convinces Ned Flanders.
  • Take That! and Arson, Murder, and Jaywalking:
    • When Smart Homer walks the streets looking for a place for smart people, he passes by places catering to idiots and morons, like Lunkheadz, The Dum-Dum Club, and The Disney Store.
    • Also a harsh one against religious people as Homer with an IQ of 105, which is a slightly above average IQ, claims he's proved God doesn't exist.
    • Marge's line about how animated shows seem to be everywhere (or were last year) is yet another burn on the animated Dueling Shows that tried to be better than The Simpsons, specifically Futurama and Family Guy, both of which suffered through Executive Meddling and were initially canceled because of low ratings and shifting timeslots on FOX.
