Just before closing time, a lady strolls into a butcher’s shop and asks, “Do you have any chickens left?”
The butcher goes over to his deep freezer, pulls out the sole remaining chicken, and places it on the scale. It shows 3 lbs.
The woman glances at the chicken and the scale, then queries, “Do you perhaps have one slightly larger than this?”
The butcher returns his only chicken to the freezer, then promptly brings it out again. This time, when he puts it on the scale, he cunningly presses his thumb on the scale pan, and the weight now reads 4 lbs.
“Perfect,” says the woman, her face lighting up. “I’ll take both of the chickens, thank you!”
