The owner has sold all his chickens spare one. The woman asks him for his biggest chicken, so he hands her the only one and says, “That’ll be $3.50.”

The woman says “For that price, I need a bigger chicken.”

The owner goes over to his freezer, places the chicken inside and acts as if he’s searching for a bigger one, then takes out the same chicken. He shows it to the woman and says, “This one will be $4.50.”

The woman says, “Okay I’ll buy both.”
