I like Aqua teen. It's an acquired taste. Metapocalypse is growing on me too.
I couldn't get into Metalocalypse - loved Sealab and really liking Frisky Dingo more and more. Robot Chicken and Tom Goes to the Mayor are great of course.
Man there are a lot of FReepers that would go ballistic over Moral Orel if they knew about it :-)
Mission Hill, ATHF, SeaLab and Harvey Birdman are some of my favorites.
