Sealab 2021, Space Ghost: Coast to Coast, The Brak Show, and Harvey Birdman: Attorney at Law were my favorite of the Adult Swim originals. I really can't pin down parts of it that were "ironic", "meta", "self-commentary", or any other thinky big words like those; I just thought they were just doing what they thought was funny. Aside from The Venture Brothers and Superjail, lots of [as] originals don't have that something extra that extends beyond the one-joke premise. I'm going to sound old for this, but I think Aqua Teen is still being made because its so cheap instead of doing anything clever, Metalocalypse gets repetitive with a massacre every episode, Robot Chicken tried too hard last season, and Morel Orel is just crap.
