My must-watch shows at the moment are Desperate Housewives and Heroes, and 24 *would* be a must-watch if it weren't opposite Heroes frown I am catching up on the old seasons of 24 in syndication, though.

My Name Is Earl and Law And Order:SVU are not a must-watch shows for me, but if I'm around when they're on, I'll watch them.

I usually have the tv on in the background with the entertainment shows (Extra, AH, ET, etc) and Leno and Conan. I just don't pay 100% attention to them.
