My favorite tv show ever was only on Fox for one season, and I believe reruns can be seen on the Scifi network. It's called "Firefly" and it is the only show I have ever seen that I could watch over and over. There are only fifteen episodes, and I've seen each one probably close to 40 times a piece.

I love this set of fantasy books by David Eddings, too...it's been years since I have read them, they had names like "The Belgariad", "The Mallorean", etc.
