Witness 1

From Tardis Wiki, the free Doctor Who reference

A man was a witness of odd events on the London Underground at Christmas in 2006. He entered the train with his friends, Jizz, Gazza and Paul. When Paul started acting strangely, the Third Doctor fought with him, and Paul, who was an alien, vanished. The man later gave his eyewitness account to UNIT. (PROSE: Jigsaw)
