Sherlock Holmes and Dr Watson decide to go camping. They pack their camping gear into the car and drive into the countryside. After a long drive and a light dinner they pitch their tent, climb inside, and are soon fast asleep in their sleeping bags. In the middle of the night Sherlock shakes Watson awake. He points to the full moon and says, "What are you able to deduce from that?" Watson thinks for awhile and replies, " I deduce that the moon revolves around the earth and that earth revolves around the sun." "Watson you fool!" said Sherlock, "our tent has been stolen."
