A woman walks into the butcher shop just before closing. She says, “Thank Heavens I’ve made it in time! Have you any turkey?” The butcher opens his fridge and takes out his only turkey, and plops it onto the scale. It weighs 4 1/2 pounds.

“Ah, haven’t you anything bigger?” the woman inquires. The butcher returns the turkey to the fridge, takes it out again, and plops it onto the scale, only this time, he keeps his thumb on the turkey. The scale shows 7 1/4 pounds.

“Marvelous!” says the woman. “I’ll have both of them please.”
