Sherlock Holmes and Professor Watson went on a camping trip. After a good meal and a bottle of wine they lay down for the night in their tent and went to sleep. Some time later, Holmes awoke and nudged his faithful friend.
Holmes: "Watson, look up at the sky and tell me what you see".
Watson: "What a clear sky. I see millions of stars, and the Milky Way".
Holmes: "What does that tell you?"
Watson "Astronomically, it tells me that there are millions of galaxies and potentially billions of planets. Astrologically, I observe that Saturn is within the Leo constellation. I deduce that the time is approximately 3 am. Meteorologically, the air appears dry, I suspect that we will have a beautiful day. Why did you ask? What does it tell you?"
Holmes paused then spoke. "Watson, you fool. Some one has stolen our tent."
