A Navajo shepherd was herding his flocks in a remote piece of land when suddenly a brand new Jeep Cherokee advanced out of a dust cloud towards him. The driver, a young man in a Brioni suit, Gucci shoes, Ray Ban sunglasses and a YSL tie leaned out of the window and asked the shepherd: "If I tell you exactly how many sheep you have in your flock, will you give me one?" The Indian shepherd looks at the yuppie, then at his peacefully grazing flock and calmly answers "sure!" The yuppie parked the car, whipped out his notebook, connected it to a cell-phone, surfed to a NASA page on the Internet where he called up a GPS [Global Positioning Satellite] navigation system, scanned the area, opened up a database and 60 Excel spreadsheets with complex formulas. Finally he printed out a 150 page report on his hi-tech miniaturized printer, turned round to the shepherd and said: "you have exactly 497 sheep!" Unexcitedly, the Navajo said, "You're right. Go ahead and take one of the sheep." He watched the young man select an animal and bundle it in his Cherokee. Then the Indian shepherd said: "If I can tell you exactly what your business is, will you give me my sheep back?" "Okay. Why not?" answered the young man. "You are a consultant" says the Navajo. "You're correct!" shouted the yuppie, "How did you guess that?" "Easy" answered the shepherd. "You turn up here although nobody called you. You want to be paid for the answer to a question I already knew. And you don't know squat about MY business because you took my durn dog."
