Probably "Only Fools and Horses" and "Blackadder". It's hard to find them online anymore. I'll probably buy copies the next time i'm in the UK. For US TV shows, favorites are the X-Files, the early seasons of Supernatural, SouthPark, Seinfeld and early Family Guy. Maybe it's just changing tastes but i haven't found any good TV shows to dig into recently other than documentaries. 101 East, Planet Earth, Trust Me I'm A Doctor, Wild New Zealand are all pretty good if you're a documentary fan.
