Tarzan

Tarzan was a fictional character about a man who lives in the jungle amongst the apes, Ace gave Nimrod (a man who strongly resembled an ape) the nickname Tarzan (DW: Ghost Light)

When Hilary Pink asked the Doctor if he had ever read Tarzan of the Apes, the Doctor replied that he had met him, too. (EDA: Eater of Wasps)

This would seem to imply that Tarzan exists as a real person in the Doctor Who Universe.
