What are TV shows that you have watched regulary?

I don't watch much television but I can quote every single episode from any given season of Sabrina the Teenage Witch. (Not kidding). And I have seen every single episode of Law & Order: Special Victims Unit at least once except for the episode entitled "Runaway." (I have been searching EVERYWHERE for it). I also like the various Johnny Cash television shows, although they don't air anymore.
