Four more series of the popular panel show, in which celebrity guests donate an exhibit of their choice to an infinite imaginary museum.

Join eminent Professor of Ignorance John Lloyd and distinguished curators Lee Mack, Bridget Christie, Alice Levine and Holly Walsh, as they source more strange and wondrous objects to fill Galleries 13 to 16 of the ever-expanding comedy edifice.

Adding to the display cases and plumping up the plinths are a host of illustrious guests, among them Lucy Beaumont, Shaun Keaveny, Graeme Le Saux, Nina Conti, Celia Imrie, Philippa Perry, Danny Wallace, Helen Fielding, Eddie Izzard, Dr Eugenia Cheng and Ade Adepitan. All come bearing donations, including the cheapest item on a wedding list, a 1980s Sony Walkman, Test Match Cricket, a cabbage, a land grant to a place that doesn't exist, a half-burned candle, Agatha Christie's favourite mug, the equals sign, the Starship Enterprise and a wildflower meadow.

Also included is a special bonus episode, 'Annual Stocktake', in which John Lloyd invites former curators Sally Phillips, Lee Mack, Jo Brand and Jimmy Carr to review the Museum's exhibits and attempts to squeeze a new donation out of each of them. In the process, he finds out what smell is worth $100,000 Australian dollars more than that of some dirty socks, which chart places Cameron Diaz one place higher than Jimmy Carr, why there is nothing particularly special about Ordnance Survey square SE830220 and what's so good about things that are not so good.
