The actor is hanging up his sonic screwdriver after four years and will appear in just two more episodes: the keenly awaited 50th anniversary special in November, and the Christmas Day edition.
Smith, 30, said it had been ‘an honour’ to play the Doctor but added: ‘When you gotta go, you’ve gotta go.’
So what Smith is really saying here is that he's quit Doctor Who because he really needs to go and take a dump, and he's just been holding it in for the last four years?
All the best to him for the future. He's been a great Doctor. Better than David Tennant by a considerable distance IMO.
