Doctor Who: The One Doctor by Clayton Hickman, Gareth Roberts

A bit silly. Six and Mel find that the planet they are visiting has just been saved from doom by an impostor, pretending to be the Doctor. Real aliens then also turn up, and the Doctor and Mel, and their impersonators, have to take part in a TV quiz and assemble some shelves to save the world again; reminiscent of the sillier bits of The Celestial Toymaker.
