A boy read a restaurant sign that advertised fat-free French fries. “Sounds great,” said the health-conscious boy. He ordered some. He watched as the cook pulled a basket of fries from the fryer. The potatoes were dripping with oil when the cook put them into the container.
“Wait a minute,” the boy said. “Those don’t look fat-free.” “Sure they are,” the cook said. “We charge only for the potatoes.”
