Difficulty: Tricky
Dennis and Richard went on a tour of a chocolate factory. At the end of the tour, they went to the reject room, where the tour guide gave Dennis a strange block of chocolate.
Richard asked Dennis to give him half. Dennis thought for a long while, and then with a knife and a cup of hot water, carefully cut the block into two identical pieces.
