What TV show do you find yourself watching most often? (doesn't have to be new...can be reruns of an old one if you watch them all the time :) What is it that keeps you coming back ?

for me it's the non-stop laughs TBBT gives me. It doesn't matter how many times i've seen the episode. I still watch it and it still makes me laugh. Mainly Sheldon. He's me except about 20X more weird.
