Matt Groening joins Conan to reveal how the Simpsons writers room actually worked — including the guiding rule that Homer could be improbably stupid but never physically impossible, and how Conan himself was hired after leaving SNL on the strength of old sketches. Groening recalls pitching 'a bee bit my bottom, now my bottom's big' with full physical commitment to a room of TV's sharpest comedy writers, and it made the show. The conversation is a masterclass in how absurdist constraints — not total freedom — produce iconic comedy.
Key Moments
Matt Groening
“A bee bit my bottom and now my bottom's big.”
Groening recalling the Homer line he pitched — and physically acted out — to a room of elite comedy writers, which ended up making the final script.
“Homer would never know what Vassar is. If he did know, he wouldn't care. He's got no stake in this. But suddenly, this is where he draws the line.”
Conan explaining his favorite Simpsons comedic device — characters suddenly knowing or caring about something completely out of character for a single perfect joke.
“Homer is saying something akin to say something good say something good say something good and then Homer says I'm watching pornography and you cut to his brain saying that's it I'm out. Then you hear footsteps and a door slam.”
Conan describing one of his favorite Simpsons gags where Homer's own brain abandons him after he says the worst possible thing to a police officer.
Matt Groening is an Emmy Award-winning writer and animator best known as the creator of The Simpsons, the longest-running American animated series and one of the most influential TV shows in history. He also created Futurama, the sci-fi animated comedy currently airing its 14th season on Hulu. Groening's work fundamentally shaped animated comedy and the landscape of primetime television.
Takeaways
1
Improbable is fine; impossible breaks the spell Groening's foundational Simpsons rule was 'things can be improbable but not physically impossible.' Homer could fall down a gorge and emerge bloody and bandaged, but he couldn't magically reassemble like a cartoon coyote. This constraint — not total freedom — is what gave the show's absurdity its comedic weight.
2
Characters can briefly transcend themselves for one perfect joke Both Conan and Groening identified a Simpsons superpower: Homer or Barney could suddenly possess knowledge or passion they'd never logically have — like Homer slamming the table over Vassar, or Barney casually explaining he and Linda Ronstadt 'had been looking for a project together for a long time.' The joke lands precisely because it's inexplicable and never justified.
3
The dumbest pitch, fully committed, beats clever every time Groening's 'a bee bit my bottom, now my bottom's big' beat a room of elite writers not because it was smart but because he stood up and physically acted it out with total conviction. Commitment to an absurd idea — not the idea's intrinsic merit — is often what gets it into the script.
4
Escalating a character's flaw needs a hard floor The Simpsons writers kept making Homer dumber season after season to top themselves, until Groening drew one absolute line: Homer could never forget his own name. Without that constraint, escalation collapses the character entirely. Creative escalation requires pre-agreed limits.

Bootleg merchandise reveals your cultural reach better than sales data Groening collected illegal bootleg Simpsons merchandise from places like Mexico specifically because the crude, wrong versions — 'Bart Sanchez' in a sombrero, Russian coloring books drawn from memory — showed how far the show had penetrated cultures that had never properly licensed it. The distortion was the signal.
