A woman walks into a butcher's shop just before closing time and asks, "Do you have any turkey?"
The butcher opens his fridge, takes out his only turkey and puts it onthe weighing scales. It weighs six pounds.
The woman looks at the turkey and at the scales and asks, "Do you haveone that's a bit bigger than this one, please?" The butcher puts the turkey back into the fridge and then takes it out again, but this time when he puts it on the scales he keeps his thumb on the turkey. The scales now show eight pounds
"That's wonderful," says the woman. "I'll take both of them, please!"
