A young man in a suit, open shirt and sports car is held up on a country lane by a large flock of sheep. Realizing that he has to make to most of the situation he makes the grassier an offer:
"If I can tell you how many sheep you have in your flock I can take on home."

The grassier is perplexed by the offer but willing to go along with it and agrees to the wager.

The young man brings out a large laptop and establishes a connection with an Earth observation satellite. Then he initiates the image-processing software and a statistical analysis program. After a short while he exclaims triumphantly, "There have exactly 342 sheep in your flock". "That's right!" says the grassier. The young man takes an animal and puts it in the passenger seat.

After a short time the grassier asks the young man: "If I can guess your profession, can I get my sheep back?" The young man agrees to the challenge. Without hesitation he laughs and says "You're a business consultant."

"That's right" says the business consultant very surprised, "but how'd you know?" he asks as he gives the sheep back. In a slow drawl the grassier says "Oh, it's easy. Firstly, nobody called you but you came anyway, secondly you tell me things I already knew and, thirdly, you know nothing about sheep. Can I get my shepherd dog back?"
