In this fabulous episode, Demitris Deech puts together his DIY flatpack of facts as he explores the history of the humble screw. Faye Hatcher, meanwhile, is very fed up of "To Do" lists especially the ones her husband insists on reading to her over breakfast. But Dave Harries knows the meaning of life is 42 because he is a huge fan of the Hitchhikers Guide to the Galaxy creator, Douglas Adams and is telling us all about him and his influence on science fiction humour.
