What's the best tv show theme song ever?

I remember, as a kid, thinking that the Dallas theme song was really cool. I wasn't allowed to watch the show, but my parents let me watch the opening credits. I also really like the theme song for Wonder Years, which was a cover of "Get By WIth a Little Help From My Friends". But I gotta go with the theme from Good Times. It's just such a soulful 70s sound that goes so well with the show, and a certain optimism in the face of trying times that I kind of like. The theme from Mr. Belvedere is my second favorite. Seriously. That is the JAM. "Streaks on the china...never mattered before...who cares?" What's your favorite?
