Greek-Australian newbie Anna Moran and her David Tennant lookalike husband Tom battle the Bandit. But who can guess the Whovian auction prices, and just what is a rattan ball?
\n\nIn our seventh slam-down, competitors must distinguish genuine sports from Doctor Who references, guess the going rate of memorabilia, and discover how much of Series 6 has stayed stuck in their synapses.
\n\nIf you have any suggestions, corrections or comments to send down the time vortex, you can tweet the show, @oldestquestion.
