Children's Hospital Children's Hospital

Send in the clown doctors. Late-night programmer Adult Swim has renewed Childrens Hospital for a fourth season, Cartoon Network announced Tuesday.

The satirical medical series is written by and stars Rob Corddry as a doctor who wears clown makeup and "blood"-splattered scrubs so he can practice what he calls the "healing power of laughter" at a hospital where the staff is more interested in tending to their overactive libidos than treating patients.

"I'm very pleased and honored by this announcement," says Corddry.  "I'm also very surprised, given that I write this show when I'm very, very drunk. Season four promises to be a cry for help."

Also returning for Season 4 are Malin Akerman, Lake Bell, Erinn Hayes, Rob Huebel, Ken Marino, Megan Mullally and Henry Winkler.
