This week, Sara Pascoe, Alan Davies, Darren Harriott and sidekick John Kearns invite everyone's favourite Frenchman Fred Sirieix into the Comedy Central attic, alongside comedians Rhys James, Jo Brand and Dani Dyer to play another medley of madcap games that will test their guessing and bluffing skills. But all that really matters is whether they can figure out the identity of the famous face hiding in John's Mystery Box.

Highlights include Fred's bizarre descriptive skills in 'Try-Act-Along', what Darren really thinks of his nosy neighbour Sue in 'Listicuffs' and the teams trying to determine what has the biggest circumference out of a traffic cone, a footballer's thigh and John's head in 'Guestimation Unknown'.
