Sitcom idea:

An escaped mental patient kills his doctor and wears his flesh, thinking that the hot woman he saw his doctor out to lunch with earlier is his wife. Turns out that hot woman is just a business contact - and a lipstick lesbian - and the doctor's wife is Kathy Bates or Melissa McCarthy or something, and super bossy and domineering. His son is an idiot who is constantly getting into trouble and the ballza doctor was heavily in debt to Chinese gangsters due to a secret gambling/Ma Jong problem.

So the flesh-wearing protagonist is in for a host of zany, dark surprises, as he attempts to navigate his new life and keep the fact that he is, in fact, an escaped lunatic wearing his psychiatrist's skin a secret.

In one episode, there is a heat wave and they all go to the beach, and the doc/lunatic-in-disguise is struggling to stay cool as he is basically wearing a head-to-toe leather jumpsuit and would be sweating like a bitch in there. So he gets all uncomfortable and tries to covertly keep cool underneath without giving away his true identity.

At the end of season one, the son finds out the truth but the pair soon bond as the son was not close to the real doctor (who would constantly pressure him about grades and medical school when the son's true passion was making stunt videos, like stapling things to his face and jumping off buildings and breaking his legs). The lunatic, it turns out, is much more supportive of the son's true inclinations and the pair soon bond, helping to keep each other's secrets and cover for each other in time of need.

Toward the end of season 2, it turns out the fat wife is actually a man wearing human flesh as well, complicating matters considerably, and the unusual family learn the true meaning of loyalty and build a life together until a heated and hilarious series climax involving a suspicious neighbour - who throughout the series has known something was not right with the family next door but couldn't quite put his finger on it; many episodes revolve around close calls with this neighbour - and a nosy FBI agent who won't quit. Things come to a head in a dramatic cat-and-mouse sequence as the family attempts to disguise themselves in the flesh of numerous people in an attempt to evade law enforcement. The final episode would feature numerous guest appearances and cameos, as various celebrities play the family members hiding in the flesh of new victims as they attempt to escape capture.

Get Charlie Brooker to write some episodes and maybe get Chris Morris to write/direct. Call it*Under My Skin* or Beneath It All or something.
