Back when this ramshackle quiz was a bonkers night out at the Edinburgh Festival, the site of deadpan comic Tim Key (nearly) falling off his track-rolling quizmaster chair routinely had us in stitches. Now, said quiz, which asks ludicrous questions then asks text-messaging service AQA to answer them, has made the jump to TV. Mark Watson is the host and tonight's baffled guests are Julia Bradbury and Red Dwarf's Robert Llewellyn.
