Beginning its six season run in 1982, St. Elsewhere garnered little critical acclaim and virtually no viewer response as a sleepy medical drama set in a dilapidated teaching hospital in Boston. In all respects, it would have been an easily forgettable hour-drama if not for the series finale, which has become the stuff of nerdy legend. In the final episode, a main character's autistic son, Tommy Westphall, is shown staring at a snow globe with a tiny version of the teaching hospital inside. Given that the final moments of the show are completely at odds with the rest of the show's 100+ episode run, it is generally assumed that all events depicted in the show were a figment of Tommy's imagination.
In our crazy modern times, such a gimmick seems interesting, but not too outlandish. I mean, just watch more than three consecutive episodes of LOST to get what I'm talking about. But the story gets better. Some bright spark assumed that if St. Elsewhere was just the figment of a character's mind, then every crossover episode it ever had must have also occurred inside little Tommy's head. The main lynchpin of this theory rests with Homicide: Life On The Street, a crime drama produced by Tom Fontana (St. Elsewhere's creator). In more than one instance, doctors from Elsewhere appear on the show, presumably making the entire Homicide run similarly a product of Tommy's psyche. One of Homicide's main characters was a cop by the name of John Munch. Yeah. This guy:
For those not in the know, John Munch later appeared as a main character in Law & Order: Special Victims Unit. Since L&O:SVU belongs to the same universe as all of the Law & Order universes, Tommy is also responsible for one of television's longest running franchises. It doesn't stop there, either. Munch appeared in an X-Files episode, an episode of The Wire, and in an episode of The Beat (also the series finale of Arrested Development. Shit yeah). Also, let us not forget his brief stint on Sesame Street.
If your mind isn't fully and thoroughly blown yet, let me just cut to the chase. Through an extremely tenuous and unlikely series of connections, over two hundred and eighty television shows currently compose what has come to be known as the Tommyverse. Or I might have just made that name up right now. Either way, think of it. A lot of minor shows, but a vast majority of stuff you've probably seen. Stuff like Cheers; Alf; M*A*S*H; Las Vegas; Heroes; I Love Lucy; The Office (both versions); Crossing Jordan; Buffy The Vampire Slayer (therefore Angel) and Firefly; Doctor Who (all incarnations); Friends; Seinfeld; The Brady Bunch; Home Improvement; Matlock; The Fresh Prince Of Bel-Air; Boy Meets World; Gilligan's Island; King Of Queens; Malcolm In The Middle; Alias; Knight Rider; Touched By An Angel; the entire Star Trek universe; the entire Crime Scene Investigation universe; and Moesha. In the unlikely event that you still care, just check out the full map below (click to enlarge), courtesy of this site. Tommy bless you, good sir.
If you want a key to the whole thing, you'll find it here. There's something else that gets me though. As a Buffy fan, I was instantly reminded of the season six episode "Normal Again", in which it is suggested that the entire Buffy universe may be the hallucination of a troubled teenage girl (who can't really kill vampires and prevent multiple apocalypses). What could this possibly mean? Are insane Buffy and little Tommy Westphall the only "real" characters on TV? I'd say: "Sure, why not."
