A man walking along a road in the countryside comes across a shepherd and a huge flock of sheep. The man says to the shepherd:
“I will bet you $100 against one of your sheep that I can tell you the exact number in this flock.”
The shepherd thinks it over and responds:
“It’s a big flock so he takes the bet.”
“973,” says the man.
The shepherd is astonished, because that is exactly right. The Shepard says:
“OK, I’m a man of my word, take an animal.”
The man picks one up and begins to walk away.
“Wait,” cries the shepherd, “Let me have a chance to get even. Double or nothing that I can guess your exact occupation … You are an economist for a government think tank.”
“Amazing!” responds the man, “You are exactly right! But tell me, how did you deduce that?”
“Well,” says the shepherd, “put down my dog and I will tell you.”
