“I USED TO RUN A BAR, I KNOW HOW THESE THINGS WORK.”

There is a theory that all TV takes place within the mind of Tommy Westphall.
The idea is that characters (as opposed to simply actors) cross-over from different shows, reappearing and disappearing as thoughts in Tommy’s head.
There is a map of this universe, available here.
For my own small part, here’s a video showing the Homicide: Life on the Street character John Munch at the opening of his bar in season three of the show, followed by Munch in season five, episode seven of The Wire, talking about how he once owned a bar.
