Head Cases is an American primetime comedy-drama television program, best known as the first show cancelled for the 2005–2006 season. It was broadcast by FOX and premiered on September 14, 2005. It was cancelled after two episodes on September 22 after disastrous ratings and critical drubbing.

Attorney Jason Payne (Chris O'Donnell) had a superstar career at a prestigious Los Angeles law firm -- that is, until his wife, Laurie, kicked him out of the house and he had a nervous breakdown. After three months at a "wellness center," Jason finds himself with no job, no place to live and no support system. Enter Russell Shultz (Adam Goldberg), an unkempt, unpredictable sufferer of explosive disorder, assigned to be outpatient "buddies" with Jason by their mutual therapist, Dr. Robinson. Payne and Shultz ultimately decide to open a law firm of their own.
