Tour guide (Doctor Who? 112)
From Tardis Wiki, the free Doctor Who reference
A tour guide once conducted a guided tour of the BBC Television Centre. He showed the visitors the Blue Peter office where Simon, Janet and the Other One were recording an episode. He also showed them the room where the BBC kept ex-Doctor Who companions, telling his group that a tenure of anything over six months guaranteed them a place there. (NOTVALID: Doctor Who? 112)
