I dont think Doctor Who can really crossover with anything,
I wasn't asking for a crossover episode; I just want to see John Munch expand his links throughout the television cosmos. He's appeared on shows as varied as Homicide
, Sesame Street
, and Arrested Development
. Why not add Doctor Who
? The TARDIS could land in New York City, the doors open, Matt Smith pops his head out and sees John Munch, and then it takes off again. Really, not that different than "The Chase."
