We watched The Three Doctors at our Guardian meeting last weekend, to commemorate the show’s 54th anniversary. The Brigadier, referring to the Third Doctor being replaced by the Second Doctor, had the best line in the episode:
“As long as he gets the job done, he can wear any face he wants.”
What a wonderful world it would be if everyone followed his philosophy! Writing like that is one of the reasons I am such an avid fan of the show.
