A man is out driving in the countryside

A man is out driving in the countryside where he suddenly comes across a big herd of sheep. He stops his car and get out waiting for the sheep to pass over the road. At the end of the herd he spots the shepherd. He goes over to the shepherd and starts a conversation.

-"If I can tell you exactly how many sheep you have, can I get a sheep as payment?"

The shepherd thinks for a while and says "sure".
So the man goes over to his car, brings up his laptop, connects to the internet through his smartphone internet sharing, connects to a passing sattelite above, takes a picture of the area, runs the picture through his recognition software and plots the result in Excel.

-"You have exactly 174 sheep!" he proudly exclaims.

-"That is correct" replies the shepherd.

So the man proceeds to take one sheep and put it in the back of his car. The shepherd thinks for a while and says

-"If I can tell you what profession you have, can I get my sheep back?"

The man looks puzzled but says "sure, go for it"

-"You're a management consultant."

-"How did you know that?!" questions the man.

-"Well, first, you come here even though I didn't ask for it. Secondly, you use a overly advanced technology to tell me things I already know. Third, you charge an absurd amount for it. Fourth, can I have my dog back?"

I told this joke to a friend who is a management consultant. He didn't like it.
