At school, Roald Dahl looked forward most to those special days when the local chocolate company sent every pupil a large box of chocolate bars for testing. Years later he wrote a children's book inspired by the chocolate testing. It was one of the first of a string of incredibly funny, rude and amazing stories, which millions of children have read and enjoyed.
