Out side of robot chicken and venture brothers adult swim Sufis now. Back in the day it was good with shows like see lab and space ghost coast to coast as well as the Brack show and aqua teenage hunger force. Now that was good TV.
Superjail, Aqua Teen Hunger Squad and Squidbillies are probably my favorite shows. The Eric Andre show deserves honorable mention. I can't really pin point why i love adult swim so much, its just so weird and different.
