Jimmy Carr hosts a big fat night of pointless sports trivia, with panellists Roisin Conaty, Judi Love, Joel Dommett, Dane Baptiste, Kerry Godliman and Tom Allen pondering why Paula Radcliffe apologised to the nation, which sports have been played on the moon, and what trademarks belong to Muhammad Ali. Charles Dance heads up the celebrity question setters, alongside the kids of Mitchell Brook Primary School.
