Pro consultant and shepherd

Surely the old dupe, but I heard it today for the first time. I liked very much, as they say, this is our everything:

Shepherd, herding a flock of sheep, is approached by a car of some type, leans out the window and says:

“If I tell you how many sheep you have in the flock, will you give me one?”

A slightly surprised shepherd replies:

- Of course, why not.

Then this guy gets a laptop, connects it to a mobile phone, establishes a connection to the Internet, goes to the NASA site, selects GPS satellite communications, finds out the exact coordinates of the place where he is located, and sends them to another NASA satellite that scans this area Ultra-high resolution photo. Then this type sends a snapshot to one of the Hamburg laboratories, which after a few seconds sends him a soap confirming that the snapshot has been processed and the resulting data is stored in a database. Through ODBC, it connects to the MS-SQL database, copies the data to the EXCEL table, and starts calculating. After a few minutes, he gets the result and prints 150 pages in color on his miniature printer. Finally he says to the shepherd:

- You have 1586 sheep in your herd.

- Exactly! That's the number of sheep in my flock. Well, choose.

A man chooses one and loads it in the trunk. And here the shepherd says to him:

- Listen, and if I guess who you work with, will you return it to me?

A little thought, the man says:

- Come on.

“You work as a consultant,” the shepherd unexpectedly says.

- It's true, damn it! And how did you guess?

“It was easy to do,” says the shepherd, “you appeared when no one called you, you want to receive payment for an answer, which I already know, to a question that nobody asked you, and besides, you don’t understand my work. SO, WHAT YOU GIVE BACK TO MY DOG
