Вообще-то, у Заходера текст немного другой, ну да ладно, смысл тот же.
А вот тоже на тему о консультантах. Извиняюсь за английский, но переводить лень.

Once upon a time there was a shepherd looking after his sheep on the
edge of a deserted road. Suddenly a brand new "Jeep Cherokee" 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 gets out and asks the shepherd: "If I guess how many sheep you have, will you give me one of them?"

The shepherd looks at the young man, then looks at the sheep which graze and says: "All right."

The young man parks the car, connects the notebook and the mobile,
enters a NASA site, scans the ground using his GPS, opens a data base and 60 Excel tables filled with algorithms, then prints a 150-pages report on his high-tech mini-printer. He then turns to the shepherd and says: "You have exactly 1,586 sheep here."

The shepherd answers: "That's correct, you can have your sheep." The
young man takes the sheep and puts in the back of his jeep. The shepherd looks at him and asks: "If I guess your profession, will you return my sheep to me?"

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

The shepherd says: You are an "Arthur Andersen" consultant!"

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

"Very simple," - answers the shepherd: "First, you come here without
being called. Second, you charge me, to tell me something I already knew. Third, you do not understand anything about what I do... because you took my dog!!!">> >>
