Matt Groening and Justin Roiland probably didn't sit in a dark room a decade ago and plan out a grand, unified theory of animation. Honestly, it's more likely they just wanted to make each other laugh. But fans? We’re obsessive. We look for patterns where there are only ink blots. Yet, when you look at the crossover history between Rick and Morty and The Simpsons, the evidence isn't just a collection of Easter eggs. It's a structural bridge.
Television history changed in May 2015. That was the night the Smith family’s spaceship slammed into the iconic Simpson living room during a couch gag. It wasn't just a cute nod. Rick Sanchez literally murdered the most famous family in television history. By mistake, sure, but he did it. Then he sent Morty to a cloning facility to "fix" them. This wasn't some non-canonical fluff. In the world of Rick and Morty, where everything is part of an infinite multiverse, that moment happened. It's real.
The Couch Gag Heard 'Round the Multiverse
The "Mathlete's Feat" episode of The Simpsons gave us the most visceral connection between these two shows. Usually, guest animators do something whimsical or weird. Rick and Morty, however, brought their specific brand of nihilism to Springfield. Rick’s indifference to the Simpson family's gruesome death—melted into yellow puddles—told us everything we needed to know about the power dynamic.
You’ve got to think about the logistics here. Rick uses a portal gun to travel between dimensions. If he lands in 742 Evergreen Terrace, it means Springfield exists at a specific coordinate within the Central Finite Curve. Or maybe it’s outside of it? Given how stagnant and unchanging Springfield is—nobody ages, the status quo is god—it might actually be a "perfect" reality that Rick usually avoids because it’s too boring.
Morty’s reaction was classic. He was horrified. Rick was just annoyed by the paperwork. This interaction established that the Simpsons aren't just a cartoon within the Rick and Morty world; they are a biological reality within their shared multiverse. This isn't just a theory. The physical vials of "Simpsons DNA" seen in the episode are a hard link.
Bill Cipher and the Gravity Falls Connection
To understand how deep this goes, you have to look at the "connective tissue" provided by Gravity Falls. Stick with me. In Gravity Falls, a notebook and a coffee mug get sucked into a portal. In Rick and Morty, those exact same items—the mug with the question mark and the notebook—pop out of a portal in the background of a scene at the Citadel of Ricks.

Now, bring in The Simpsons. In the Treehouse of Horror XXVI, we see Bill Cipher from Gravity Falls appear in a background shot. Later, in Rick and Morty, Bill Cipher is visible on a monitor in a therapy office. This creates a "triangle" of connectivity. If Show A is linked to Show B, and Show B is linked to Show C, then Rick and Morty and The Simpsons are inevitably part of the same cosmic ecosystem.
It’s a bizarre form of corporate and creative synergy that feels organic because the creators are all friends. They’re playing in each other's sandboxes. This isn't like the Marvel Cinematic Universe where every "connection" is a calculated move to sell toys. This is more like a group of high-level animators tagging each other's work like graffiti artists.
Why the Humor Styles Actually Complement Each Other
People say The Simpsons is heart and Rick and Morty is cynicism. I think that's a bit of a surface-level take. Honestly, early Simpsons (Seasons 3 through 8) was incredibly cynical about American institutions. It mocked the nuclear family, the church, and the government with a bite that Rick and Morty inherited.
Rick Sanchez is, in many ways, the final evolution of the "disruptor" archetype that Homer Simpson pioneered. Homer was the bumbling idiot who broke things by accident. Rick is the genius who breaks things on purpose. When they met in the couch gag, it felt like a passing of the torch. Or a stealing of the torch. Rick basically looked at the Simpsons' legacy and said, "I can do this faster and with more trauma."
The pacing is the biggest difference. A modern Rick and Morty episode has more plot in twenty minutes than a whole season of The Simpsons did in 1992. But the DNA is there. You can’t have the meta-commentary of Rick without the "fourth wall" breaking of the classic Simpsons era.

Hidden Cameos You Probably Missed
Beyond the big crossover, there are tiny flickers of Springfield in the background of the Smith family's adventures. In the episode "The Whirly Dirly Conspiracy," there are alien species in the background that bear a striking resemblance to some of the background characters in The Simpsons' "Treehouse of Horror" segments.
- The Beer: Duff Beer has appeared as a background prop in various dimensions Rick visits.
- The Voice: Dan Castellaneta (Homer) and Justin Roiland have both spoken about the mutual respect between the booths.
- The Backgrounds: There’s a scene in the Rick and Morty comics—which are generally considered "soft canon"—where a character looks suspiciously like a blue-haired Marge Simpson in a futuristic setting.
Is it a coincidence? No. The artists at Starburns Industries and later Titmouse, Inc. grew up on the yellow family. They can’t help but put them in. It's like a visual reflex.
The Existential Crisis of the "Yellow" Dimension
Think about the horror of being a Simpson through Rick's eyes. Rick hates the idea of being trapped in a loop. He hates the "Citadel" because it’s a bureaucracy of his own making. Springfield is the ultimate prison. It’s a town where time has stood still for over thirty-five years. Maggie is still a baby.
If Rick spent more than ten minutes in Springfield, he’d lose his mind. He’d probably try to "liberate" them by destroying the timeline, which explains why he was so quick to just clone them and leave in the crossover. He didn't want to get stuck in their slow-moving, episodic reality. To Rick, the Simpsons represent the one thing he fears most: a life where nothing ever changes.
What This Means for Future Crossovers
We haven't seen a full-length crossover episode yet. We’ve had the couch gag and various cameos, but never a "The Simpsons Guy" style event. Why? Probably because the tones are so vastly different that a 22-minute story might feel disjointed. The Simpsons has become a legacy brand, a bit softer around the edges. Rick and Morty still wants to be the edgiest kid in the room.

But the demand is there. Every time a new "Treehouse of Horror" is announced, fans look for a portal. Every time Rick jumps to a new reality, we scan the background for a Kwik-E-Mart. It’s the ultimate "Where’s Waldo" for animation nerds.
How to Find Every Connection Yourself
If you want to track the overlapping lore of Rick and Morty and The Simpsons, you need to stop watching the main plot and start looking at the edges of the frame.
Start with The Simpsons Season 26, Episode 22. Watch the couch gag frame-by-frame. You’ll see Slorm (from Futurama) and references to other Roiland-adjacent projects. Then, pivot to Rick and Morty Season 2, Episode 4, "Total Rickall." Look at the various "wacky" characters that appear—many of them are stylistic nods to the "ugly-cute" character design philosophy that Matt Groening popularized in the late 80s.
The most effective way to see the influence is to watch The Simpsons episode "Homer's Enemy" (the Frank Grimes one) and then watch any "Rick-heavy" episode. You’ll see the exact moment where the "jerkass" protagonist evolved into the "sociopathic" protagonist. It’s a direct line of descent.
- Watch the Couch Gag (2015): This is the "ground zero" of the crossover. It establishes that Rick can travel to the Simpson dimension.
- Check the Comics: The Rick and Morty comic books from Oni Press often feature much more explicit nods to Springfield because the legal hurdles for "parody" in print are slightly different than on network TV.
- Analyze the Backgrounds: Pay attention to the "multidimensional" scenes. Animators often hide "Blinky," the three-eyed fish, in alien tanks.
- Listen for Meta-Commentary: Both shows frequently make fun of the "other" show's network (FOX vs. Adult Swim/Warner Bros).
This isn't just about two shows sharing a joke. It's about the fact that modern animation is a small circle. The people who write for Rick have pictures of Homer on their desks. The people who draw the Simpsons are watching Rick and Morty on their lunch breaks. They are part of the same creative DNA, regardless of which studio owns the rights.
The next time you see a green portal, don't be surprised if it opens up right in front of a pink sedan in a driveway in Springfield. It’s already happened once. In an infinite multiverse, it’s happening right now, over and over again.
