Once upon a time there was a shepherd looking after his sheep on the side of a deserted road. Suddenly a brand new Porsche  screeches to a halt.

The driver, a man dressed in an Armani suit,  Cerutti shoes, Ray-Ban sunglasses, TAG-Heuer wrist-watch, and a Pierre   Cardin tie, gets out and asks the Shepherd:
"If I can tell you how many  sheep you have, will you give me one of them?"

The shepherd looks at  the young man, and then looks at the large flock of grazing sheep and  replies:
"Okay."
The young man parks the car, connects his laptop to the  mobile-fax, enters a NASA Webster, scans the ground using his GPS, opens a database and 60 Excel tables filled with logarithms and pivot tables,  then prints out a 150 page report on his high-tech mini-printer. He turns to  the shepherd and says, "You have exactly 1,586 sheep here."

The  shepherd cheers," That's correct, you can have your sheep."

The young  man makes his pick and puts it in the back of his Porsche.

The shepherd  looks at him and asks: "If I guess your profession, will you return my  animal to me?"

The young man answers, "Yes, why not". The shepherd says,  "You are an IT consultant ".

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

"Very simple," answers the shepherd. "First, you came here without being  called. Second, you charged me a fee to tell me something which I already knew,  and third, you don't understand anything about my business...

Now  can I have my DOG back?"
