I voted Rick & Morty, and would put Archer as a very close second. Family guy comes in third, because I just want to rail the daylights out of Lois. South Park is fourth, and after that, I don't really consider any of the rest adult. In fact, Family Guy isn't really all that adult, but it is risque, as is American Dad. I also love The Venture Brothers, and Metalocolyps, or however the hell you spell it.
