A shepherd was herding his flock....{joke}

 A shepherd was herding his flock in a remote pasture when suddenly a
brand-new BMW drives up in a cloud of dust. The driver, a young man
in an Armani suit, Gucci shoes, Ray Ban sunglasses and YSL tie, leans
out the window and asks the shepherd: "If I tell you exactly how many
sheep you have in your flock, will you give me one?"
 The shepherd looks at the man, obviously a yuppie, then looks at his
peacefully grazing flock and calmly answers: "Sure. Why not?"
 The yuppie parks his car, whips out his Dell notebook commputer,
connects it to his AT&T cell phone, surfs to a NASA page on the
internet, where he calls up a GPS satellite navigation system to get
an exact fix on his location which he then feeds to another NASA
satellite that scans the area in an ultra-high-resolution photo.
The young man then opens the digital photo in Adobe Photoshop and
exports it to an image processing facility in Hamburg, Germany.
Within seconds, he receives an email on his Palm Pilot that the image
has been processed and the data stored. He then accesses a MS-SQL
database through an ODBC connected Excel spreadsheet with hundreds of
complex formulas. He uploads all of this data via an email on his
Blackberry and, after a few minutes, receives a response. Finally, he
prints out a full-color, 150-page report on his hi-tech, miniaturized
HP LaserJet printer and finally turns to the shepherd and says:
"You have exactly 1586 sheep."
"That's right. Well, I guess you can take one of my sheep.", says the shepherd. He watches the young man select one of the animals and looks on amused as the young man stuffs it into the trunk of his car.
Then the shepherd says to the young man: "Hey, if I can tell you exactly what your business is, will you give me back my sheep? "
 The young man thinks about it for a second and then says:"Okay, why not?"  "You're a consultant." says the shepherd.
 "Wow! That's correct," says the yuppie, "but how did you guess that?"
 "No guessing required", answered the shepherd.
 "You showed up here even though nobody called you; you want to get
paid for an answer I already knew, to a question I never asked; and
you don't know crap about my business… Now give me back my dog."
