How Many Sheep You Have
Once upon a time there was a shepherd looking after his flock on the edge of a deserted road. Suddenly a brand new Jeep Cherokee screeches to halt next to him. The driver, a young man dressed in a Saville Row suit, handmade shoes, Rayban sunglasses, Rolex watch, Jermyn Street shirt and Gucci tie gets out and asks the shepherd "If I can guess how many sheep you have, can I keep one?".
The shepherd looks at the young man, and then looks at the grazing sheep and replies "Okay".
The young man parks the car, connects the notebook and the mobile fax, enters a NASA website, scans the ground using his GPS, opens a database and 60 excel tables filled with logarithms, then prints out a 150 page report on his high-tec mini printer. He turns to the shepherd and says "You have exactly 1,586 sheep here".
The shepherd answers "That's correct, you can have your sheep".
The young man takes an animal and puts it in the back of his Jeep. The shepherd looks at him and asks "If I can guess your profession will you give me my animal back?". The young man amswers "Yes, why not".
The shepherd says "You're a consultant". "How did you know?" asks the astonished young man.
"Very simple" replies the shepherd. "First, you came here without being asked. Second you charged me a fee for telling me something I already know. Third, you don't understand anything about my business. Now can I have my dog back?".
