Numberjacks has been my favourite childhood TV show since I was 4 years old. The show is about little multi-coloured anthropomorphic numbers that solve a variety of mathematical problems in the real world. The problems can either be caused one of the Meanies or one of the younger Numberjacks (0, 1 or 2). The Numberjacks live in a sofa owned by a unknown family in London and often use Brain Gain to solve the problems that occur.
