If you like Children’s Hospital, the weird fake show that was in some commercials that they did in between parts of the episode at one point took on a life of its own and became NTSF:SD:SUV::, also on Adult Swim. Paul Scheer, his wife that doesn’t share a name with him at all (June Diane Rafael, I think), and various others, including Captain Janeway in a roll I don’t hate for a change.
If we’re recommending weird ass AS shows that we like, though:
Moral Orel - Three seasons, finished, except there will be specials in the future. It started out as one thing and then turned into something very different that kind of made me want to be dead a little bit, but in a good way? It’s a good program, but it just stops being funny at a point and starts being a show about a closeted man’s abusive relationship with his family. If you watch Community, this is Starburns’s first show.
Mary Shelly’s Frankenhole - This is Starburns’s second show. Not as consistently good as the first, but still a perfectly serviceable stop motion production. Ongoing.
Aqua Teen Hunger Force/Aqua Unit Patrol Squad 1 - So, this show changed its name and series ID last year for no good reason. You might call it postmodernist comedy. Many episodes are not the greatest, but when the show is the greatest (to name a few episodes, Love Mummy, Hand Banana, Ezekiel, Shake Like Me, and The Intervention), it is totally the greatest.
Lucy, Daughter of the Devil - Before Loren Bouchard got his big break making what seems to be the next bubble show on Fox (Bob’s Burgers), he did shows like this for AS. There is no dimension in which this isn’t really a superior show to Bob’s Burgers, except for the one where Bob’s Burgers is actually still on the air, whereas this one fell down with an audible splat after a single season. Still worth watching.
Harvey Birdman, Attorney at Law - I’d watch it for Colbert alone. Three seasons, pretty much done since Colbert got his own show.
Robot Chicken - Probably a show that most of this board’s participants should be watching anyway, since it’s basically the crystallization of your childhood in humor form. Basically, Seth Green plays with toys for fifteen minutes in a stop motion fashion. Apparently every single human has done a voice for him at some point. Note that this is the thing that finally convinced me that maybe Tila Tequila is actually kind of awesome because she gets it, though the whole ICP incident that immediately followed her appearance leaves that suspicion unconfirmed.
