A woman walks into a butcher's shop just before closing time and asks, "Do you have any chicken?"
The butcher opens his fridge, takes out his only chicken left and puts it on the weighing scale. It weighs 1.5 kg.
The woman looks at the chicken and at the scale and asks, "Do you have one that's a bit bigger than this one?"
The butcher puts the chicken back into the fridge and then takes it out again, but this time when he puts it on the scale he craftily keeps his thumb on the scale pan. The scale now shows 2 kg.
"That's wonderful," says the woman. "I'll take both of them, please!"
In situations like these you'll know that the devil is real
