John Lloyd and Phill Jupitus are joined by space-obsessed comedian Helen Keen, entrepreneur and Wikipedia founder Jimmy Wales and museum curator and Ig Nobel laureate Kees Moeliker.

This week, the Professor of Ignorance John Lloyd and his new curator Phill Jupitus welcome the space-obsessed star of Radio 4's It Is Rocket Science Helen Keen; the internet entrepreneur and founder of Wikipedia Jimmy Wales; and the curator of the Natural History Museum of Rotterdam Kees Moeliker, who won an Ig Nobel Prize for his study of Homosexual Necrophilia in the Mallard Duck.

This week, the Museum's Steering Committee discusses a smuggling ring 27 kilometres in circumference ; why the largest reference work in the history of civilisation has room for a list of sexually-active popes; how a sparrow became Holland's most famous martyr to TV Light Entertainment; how invoking The Wand helped put Americans in space; and how Africa will be transformed by a £10 gadget.

The show was researched by James Harkin and Stevyn Colgan of QI.

The producers were Richard Turner and Dan Schreiber.
