This got me in the right direction. Thanks. I found this list for "dark sitcoms" that helped.

It's Always Sunny in Philadelphia, South Park, Rick and Morty, Metalocalypse, Archer, The Boondocks, Reno 911!, Superjail!, Moral Orel, The IT Crowd, Squidbillies, Wonder Showzen, Snuff Box, Tim and Eric Awesome Show, Great Job!
Metalocalypse is good, but there is an over-arcing storyline that you might miss if you watch it out of order.
