Sherlock Holmes and Dr. Watson both retired from crime solving and decided to spend a few years touring the English countryside. Shortly into their trip at the end of one day they lay down for the night and went to sleep. Some hours later, Holmes awoke and nudged his faithful friend. Holmes said: Watson, look up and tell me what you see.

Watson said: I see a fantastic panorama of countless stars.

Holmes: And what does that tell you?

Watson pondered for a moment: Astronomically, it tells me that there are millions of galaxies and potentially billions of planets. Astrologically, I observe that Saturn is in Leo. Horologically, I deduce that the time is approximately a quarter past three. Theologically, I can see that God is all powerful and that we are infinitely small and insignificant. Meteorologically, I suspect that we will have a sunny day tomorrow with a low probability of rain.

Why? What does all that tell you, Holmes?

Holmes was silent for a moment then spoke: Someone has stolen our caravan.
