What's Your Favorite TV Theme?

The guys at TV Squad are talking about the greatest TV themes of all time. According to an article on AOL, the world has narrowed it down to Happy Days and Gilligan's Island.

Of course, they aren't even talking about the about the original Happy Days theme. "Rock Around the Clock" I could actually get on board with. Welcome Back, Kotter (59 percent) versus Friends (41 percent) was quite the grudge match. However, I am completely disgusted that Good Times didn't even make it into the competition.
