THE CONSULTANT

A shepherd was looking after his sheep on the edge of a deserted road. Suddenly a brand new Mercedes SUV screeches to a halt next to him. The driver, a young man dressed in a Brioni suit, Cerrutti shoes, Ray-Ban glasses, and a YSL tie got out and asked the shepherd: "If I can guess how many sheep you have, will you give me one of them?" 

The shepherd looked at the young man, then looked at the sheep grazing a few yards away and said: "All right." The young man parked the car,
connected a notebook computer to his cellular telephone, entered a NASA
website, scanned the ground using his GPS, opened a data base and 60 Excel
tables filled with algorithms and then printed a 150-page report on his
high-tech mini-printer. He then turned to the shepherd and said: "You have
exactly 1,586 sheep here."

The shepherd answered: "That's correct; you can have your one sheep." The
 young man took the sheep and put it in the back of his SUV.

The shepherd watched him load the sheep and asked: "If I can guess your
 profession, will you return my sheep to me?"

The young man answered: "Yes, why not."

The shepherd thought a moment then said: "You are a consultant!"

"How did you know?" asked the young man.

"Very simple", answered the shepherd: "First, you come here without being
 called. Second, you charge me a sheep to tell me something I already know.
 Third, it is obvious that you do not understand anything about what I do.

You took my dog!
