The Tommy Westphall Universe Hypothesis
Young Tommy Westphall was an ancillary character of the hit 1980s medical drama "St. Elsewhere." The show, which ran for six years, pulled a major twist in the 1988 series finale when it strongly suggested that the entire series along with all its characters, mishaps and other happenings, were the product of the autistic child's imagination. By this logic, conspiracy theorists have deduced that any other show featuring a "St. Elsewhere" character is also one of Tommy's internal creations, and any other series that said show crossed over to is affected as well. Since one of the doctor characters appeared on "Homicide: Life on the Street," the latter show is also part of Tommy's imaginations. So, this impacts like 10 or 20 shows? Wrong -- try 375 (at last count). That's right, folks. "St. Elsewhere" is clearly the Kevin Bacon of the television show industry.
Proponents of this theory have gone so far as to suggest that all of these shows exist in their own specific universe, or even a multiverse (I didn't know such a thing existed) chock-full of all our favorite characters with their intermingled storylines. If shows like "The Simpsons," "X-Files," "Law & Order," "The Facts of Life" and even "Friends" never truly existed in this universe, I'm going to figure out how to book passage to wherever the heck theirs is located [sources: McDuffie, The Tommy Westphall Universe]. "The Rachel" most definitely happened, in my mind, and no one can tell me otherwise!
