What is your favorite TV show ever?

Mine is Smallville...I love the storyline... I am addicted to that show... I actually didnt start watching till about 3 years ago...A friend of mine had season 1 on dvd...I was complaining to him that there weren't any good shows on tv anymore...He said that I needed to check out smallville...I was like nahhhhhh...I dont think so...He said that I reeeeeeeeally needed to check it out...So he informs me of his season 1 dvd set and I borrowed it...OMG from then on I was hooked...I had to actually go out and buy the next 4 seasons on dvd because they were currently airing season 6 LOL...Anyway...What is YOUR favorite TV show ever!?!?!?!?
