Outnumbered star Hugh Dennis takes on a wallpapering challenge, the Man Lab orchestra prepares for its debut concert at famous London church St Martin-in-the-Fields, and the experts build their own cinema, complete with popcorn and a Wurlitzer organ. The team also constructs a sky rocket, two men settle a 25-year-old quarrel by duelling with sabres, and James uses modern technology to help a man on a first date. Last in the series.
