There's an anime series called "Death Note" which was surprisingly good.
If you haven't tried Lost, go for it.
First season of Desperate Housewives was pretty funny, somehow lost interest after the first season though.
The Comedy Central Roasts are good fun (Charlie Sheen, Bob Saget, inter alia).
First Season of The Walking Dead (the AMC show).
Weeds.
Jericho.
Battlestar Galactica.
