Top two right now would be South Park and Futurama... love that CN is doing marathons of South Park to celebrate their new season.
Oh man.. Archer, Futurama, South Park, Aqua Teen Hunger Force, Bob's Burgers, The Boondocks.. probably more. Animated shows are virtually all I watch with a few exceptions Fun Topic!
Futurama remains to be one of my favs. South Park wears off in the end to the point it becomes lame and I really doubt the sense of humour of people who have Family Guy as a favourite (as I have always done)
Archer is my current fav thing to watch but I gotta lot of for kid shows like Adventure Time and nicks Avatar stuff.
