A shepherd was herding his flock in a remote pasture when suddenly a brand new Jeep Cherokee appeared out of a dust cloud heading toward him. The driver, a young man in an Armani suit, Gucci shoes, Ray Ban sunglasses and a YSL tie leaned out of the window and asked our shepherd: "If I can tell you exactly how many sheep you have in your flock, will you give me one?" The shepherd looks at the yuppie, then at his peacefully grazing flock and calmly answers, "Sure!" The yuppie parks the car, whips out his cell phone, surfs to a NASA page on the Internet where he calls up a GPS satellite navigation system, scans the area, opens up a database along with some 60 Excel spreadsheets with complex formulas.
Finally, he prints out a 15 page report on his hi-tech miniaturized printer, turns around to the shepherd and says: "You have here exactly 1,586 sheep!" "That is correct. You may take one of the sheep" says the shepherd. He watches the young man select an animal and bundle it in his Cherokee.
Then the shepherd says: "If I can tell you exactly what business you are in will you give me my sheep back?" "Okay, why not!" answers the young man. "You are a consultant," says the shepherd.
"That is correct" says the yuppie. "How did you guess that?" "Easy," answers the shepherd. "You turn up here unannounced, you wanted to be paid for the answer a question I already knew the answer to, and you don’t know anything about my business…because you took my dog."
