I just discovered this recently – it’s a very brief show on Adultswim, and it’s…well, it’s incredibly random humor. Sort of a Scrubs on mescaline.
An interview with Dr. Maestro gives you a good idea how odd the show is.
And here is (I kid you not) an entire episode. It’s a fast show. One of the funnier aspects, is that it always starts with “Previously, on Children’s Hospital”, and the clips from the last show never ever happened.
