Opinion on Ricky Gervais's new series Derek may be divided, but the critical acclaim for US sitcom Louie is pretty much universal. And tomorrow night, 24 hours before the second episode of Derek airs on C4, Fox premieres the episode of Louie in which Gervais plays the world's worst doctor.
Louie is the creation of stand-up comedian and friend of Ricky Gervais, Louis CK. He plays a downbeat version of himself who, in this episode, visits his doctor because he fears he has a serious illness.

See the teaser video below. Warning: contains swearing and some offensive material (although we've seen the whole scene and a lot of the rest of it is much more offensive than this...)
If you were glad that clip ended when it did, definitely don't watch this one:
