Ok, so, this is my favorite, not because I love the shows, although I do like some of them, but because it’s fun to chain links and how long you can make it.

We start with the “Munchiverse”, most people know Detective John Munch from his long career in Law & Order SVU, and obviously all of the Law and order are in the same universe, but also they’ve had crossovers with Chicago Fire which is in the same universe as Chicago PD and others. They’ve also had crossovers with FBI and New York Undercover. But I said this is the Munchiverse, and I only mentioned Munch once, this is where it gets interesting, X-Files has an episode where detective John Munch shows up, he also shows up in Arrested Development and The Beat. And going one extra link X-Files is canonically set in the same universe as Twin peaks. Going back to Munch, he’s originally from another TV show called Homicide: Life on the street, and in that TV show they investigate a doctor from the TV show St. Elsewhere, in that TV show someone mentions working with a Dr from M.A.S.H. I’m sure more links could be made.
