Sherlock Holmes and Dr Watson are out camping. They pitch their tent under the stars and go to sleep. Suddenly, in the middle of the night Holmes wakes Watson up.
"Look up, Watson," Holmes says, "and tell me what you see."
"I see billions of stars," says Watson.
"And what do you deduce from that?" says Holmes.
Watson thinks for a minute. "Well, Astrologically, I deduce that Saturn is in Capricorn.
Astronomically, that it is 3:00 am. Meteorologically, that tomorrow will be a beautiful day.
Theologically, that God is all-powerful, and we are small and insignificant.
What do you deduce?"
Holmes sighs. "Watson, you idiot. I deduce that someone has stolen our tent."
