So here’s the deal: Somewhere between earnest medical drama and surreal existentialism, the creators of St. Elsewhere accidentally spawned one of the weirdest and most enduring pop culture theories of all time. It’s called the Tommy Westphall Universe Theory, and it suggests that a staggering number of TV shows—like Breaking Bad, The Office, Firefly, and Supernatural—all exist in the imagination of an autistic boy named Tommy, who spent six seasons barely being a character on St. Elsewhere.
This theory isn’t new. It’s been dissected, debunked, and memed to death. But it refuses to die, partly because it’s ridiculous, and partly because it forces you to confront the uncomfortable reality that everything you love about TV might not just be fake—but fake within fake.
Let’s break it down, starting with the snow globe.
The Ending That Blew Everyone’s Mind
In the final scene of St. Elsewhere, a show about a gritty Boston hospital that aired in the 1980s, the camera pans away from the hospital’s main characters to reveal Tommy Westphall, the autistic son of Dr. Donald Westphall, staring into a snow globe. Inside the globe? A model of St. Eligius Hospital, where the entire show took place.
Then, things get weirder. Dr. Westphall isn’t a doctor anymore—he’s a construction worker. Another main character, Dr. Auschlander, is suddenly Tommy’s grandfather. As the adults talk in the background, wondering what Tommy’s thinking about all day, you realize: The whole series—every patient, every surgery, every melodramatic subplot—was just something Tommy imagined while playing with his snow globe.
When this aired in 1988, people either thought it was profound or infuriating. But nobody thought it would redefine how nerds on the internet would interpret television 30 years later.
The Birth of the Tommy Westphall Universe
Here’s where the theory takes a left turn into absolute madness. If St. Elsewhere is just in Tommy’s head, then what about the shows it crossed over with? For example, there’s an episode where characters from St. Elsewhere visit the bar from Cheers.
Simple logic (or insane logic, depending on your perspective) dictates that if St. Elsewhere is imaginary, then Cheers must also be imaginary. And if Cheers is imaginary, so is Frasier, its spin-off. And if Frasier is imaginary, then so is The John Larroquette Show, where a character from Frasier makes a cameo.
See where this is going? It’s a chain reaction of interconnected TV shows, all dragged into the snow globe by association. It’s like Six Degrees of Kevin Bacon, but instead of Kevin Bacon, the central figure is a kid with a snow globe and a massive imagination.
How It Works: Connecting Everything to Everything Else
The Tommy Westphall Universe starts small. Direct crossovers like the St. Elsewhere-to-Cheers pipeline are easy to follow. But the web quickly gets ridiculous. Here’s a taste:
- St. Elsewhere → Cheers → Frasier → The John Larroquette Show → references to Wolfram & Hart from Angel.
- Angel mentions Weyland-Yutani, the corporation from Aliens, which also appears in Firefly.
- Firefly links to Doctor Who through props and brand references.
Now you’ve connected a Boston hospital to a sci-fi space western and a time-traveling alien in a blue police box.
Or take The Office:
- St. Elsewhere → Homicide: Life on the Street → Detective John Munch crosses over into The X-Files → The X-Files mentions numbers from Lost → Lost connects to The Office through a character who worked at Dunder Mifflin’s paper supplier in the UK.
It’s like watching a conspiracy theorist connect random dots on a corkboard, but instead of UFOs, they’re proving that Jim Halpert and Mal Reynolds are figments of Tommy Westphall’s imagination.
Does This Even Make Sense?
Here’s the thing: The Tommy Westphall Universe only works if you fully buy into the idea that every crossover or shared reference means the two shows are part of the same reality. But there’s no rule saying a crossover makes two shows cosmically inseparable. Maybe Cheers just exists as a TV show in Tommy’s world. Maybe he caught an episode of it while playing with his snow globe.
Even if you suspend disbelief and accept the premise, what about real people who appear in these shows? Alex Trebek showed up on Cheers. Does that mean Alex Trebek is a figment of Tommy’s imagination? If so, does Tommy also imagine Jeopardy!? And what about us, the audience? Are we part of Tommy’s dream, too?
The Real Point of the Theory
Honestly, the Tommy Westphall Universe isn’t about Tommy at all. It’s about TV. It’s about how interconnected pop culture has become and how those connections reflect the ways we think about fiction. The theory says less about St. Elsewhere and more about us—the fans who spend hours tracing the invisible threads between characters, worlds, and timelines.
It’s also a giant middle finger to the idea that fiction needs to stay in its lane. Why can’t the same fictional cigarettes appear in The X-Files and Breaking Bad? Why can’t a fictional university pop up in both Law & Order and Murder, She Wrote? Fiction doesn’t exist in a vacuum, and neither do we.
Final Thoughts: Tommy’s Snow Globe Is All of Us
The Tommy Westphall Universe is ridiculous, self-referential, and completely unnecessary—and that’s why it’s great. It’s not about whether it’s true. It’s about how fun it is to imagine that every TV show you’ve ever loved is just one thread in a massive cultural tapestry, all tied together by a single, absurd idea.
And maybe that’s what Tommy Westphall represents. Not a kid dreaming up fake hospitals and sci-fi epics, but the way we, as viewers, dream up connections between the stories we love.
So the next time you’re watching The Office or Breaking Bad or Firefly, remember this: Somewhere out there, Tommy Westphall is staring into his snow globe. And he’s imagining you, imagining him, imagining all of it.
