A shepherd was bringing his large flock of sheep down a dusty road when a man in a Ferrari drove up and stopped. He got out of his car wearing an expensive Armani suit and had a laptop computer in his hand.
He said, “What a wonderful flock of sheep you have here, I’ll make a deal with you. If I can tell you how many sheep you have in your flock in less than a minute, you give me one sheep. How about it?”
The shepherd agreed.
The man scanned the flock with his computer cam and began typing on the laptop. In less than 45 seconds he shouted “You have 1253 sheep!”
“Yes, exactly!” said the shepherd. “You can have a sheep.”
The shepherd watched the rich man carry an animal to his car.
“Wait a minute” said the shepherd, “I’ll make a deal with you. If I can tell you what kind of work you do for a living, you give me back my animal, OK?”
“It’s a deal” said the rich man.
“You are an IT consultant” said the shepherd.
“Wow, that’s right, how did you know?” asked the IT man.
“Three reasons” said the shepherd. “One, you came and asked for work without me calling you. Two, I had to pay you to tell me something I already knew, and three you don’t understand my business at all. I don’t think you know the first thing about shepherding. Now give me back my dog!”
