Mould and Arrowsmith have been creeping further onto the comedy radar in recent years, and this show contains everything that we have come to expect from this fantastic duo: an abundance of self-proclaimed geeky jokes, numerous science fiction references, fantastic use of technology in boosting their gags, and providing the basis of many sketches, and (again, self-proclaimed) few actual jokes. But do not let the latter deter you in any way; this pair are not interested in garnering cheap belly laughs. Instead they go for a through-rein of continual warm humour that builds throughout the show before finishing in a dazzling climax and it works with a refreshing brilliance.Their show builds on the success of last year's Inventions, continuing their regular themes of technological wizardry and clever word play. Last year I loved their show; this year their work is even sharper and clearer, moving through topics with ease and throwing in brilliant one-liners that cut straight to the chase. The material includes a long-running discussion about the use and relevance of the iPad, conversations with God through the medium of Twitter, a host of television shows and a clever parody involving stationary. Functioning as half-conversation between each other, and half-sketches, the show moves quickly through these topics yet still manages to retain a cohesive structure where nothing is forgotten and several things referred to again across the sketches. This year's production pushes their regular use of Powerpoint even further to include the use of actual 3D - and yes, it does actually work properly and to great effect! Initially its use is kept to a minimum but cleverly used within their sketches, but the last section of the show unfolds in the manner of a thrilling Doctor Who adventure. It is a huge technological challenge but brilliantly executed. The success of Mould and Arrowsmith arises from their natural and lovely chemistry with each other. Although purposeful competitiveness is used within their content, the two have such an affinity and connection with each other that just makes everything work. Their intelligence and wit permeates everything and ultimately is responsible for making this show unmissable. Theirs is a show of originality and warmth, and despite their declaration at the beginning, I still found myself laughing out loud a lot. Definitely one to watch!
