A man approached a sheep farmer and said, "If I tell you how many sheep you have down in the valley, can I keep one?" The farmer glanced at the vast field of sheep, eyed the stranger carefully, snickered, and then accepted the bet. The stranger looked carefully across the rolling hills, scanning it left and right, then said, "5,279."

"Holy Cow!" the startled farmer exclaimed. "How did you do that?"

"Well, I'd rather not say," answered the man. "Now can I have my sheep?"

The farmer sighed, "A deal is a deal, I guess." The stranger picked out an animal and began to lead it away. The farmer watched in silence for a moment, then called after the man. "Wait! If I can guess where you are from, will you give me back my animal?"

"Fair enough," the man agreed with a grin. "You're from New York," guessed the farmer.

Instantly the stranger's smile turned to a frown. "How did you know?"
