The shepherd looked at the man, obviously a yuppie, then looked at his peacefully-grazing flock and calmly answered: 'Sure'.
'That is correct; take one of the sheep' said the shepherd. He watches the young man select one of the animals and bundle it into his car. Then the shepherd says: 'If I can tell you exactly what your business is, will you give me back my animal?'
'OK, why not' answered the young man.
'Clearly, you are a consultant' said the shepherd.
'That's correct' says the yuppie 'but how did you guess that?'
'No guessing required' answers the shepherd. 'You turned up here although 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'.
