Coming home from work, a woman stopped at the corner deli to buy a chicken for supper. The butcher reached into a barrel, grabbed the last chicken he had, flung it on the scales behind the counter, and told the woman its weight. She thought for a moment and then said, "I really need a bit more chicken than that," she said. "Do you have any larger ones?"
Without a word, the butcher put the chicken back into the barrel, groped around as though finding another, pulled the same chicken out of the barrel and placed it on the scales.
"This chicken weighs one pound more," he announced. The woman pondered her options and then said, "OK, I'll take them both!"
