Dead Ringers

Dead Ringers was a British radio and television comedy impressions show airing from 2000 to 2007. The show parodied several versions of the Doctor during its tenure.

Jon Culshaw played multiple Doctors on Dead Ringers, most notably the Fourth and Tenth.

Phil Cornwell parodied the Ninth Doctor in a sketch entitled Christmas Day at Doctor Who's. In the spoof, Christopher Eccleston comes home to his family, die-hard Star Trek fans, and has to admit to them that he is going to play the next Doctor. And the end of the sketch, he agrees to only do one year to appease his bitter relatives.

In another sketch, the Tenth Doctor discusses the problems spending Christmas with your past incarnations. The Second, Fourth, Seventh and Ninth Doctors sit in front of the TV declaring several famous people such as Cat Deeley and the Queen as aliens. They give each other presents, mostly unwanted. The Tenth Doctor brings out a turkey covered in tin foil, which frightens the Second Doctor, as all his villains were mad from tin foil. The Fourth Doctor is in the kitchen spiking the punch. The Tenth wants to watch something good on TV, while the Ninth calls his predecessor poncy. After the party, the Tenth Doctor, drunk says his previous selves were not bad people and that they like him. He staggers away, with a sign on his back saying "exterminate me".
