A young man told the doctor: “You have to help me, I hurt all over.”
“What do you mean?” said the doctor.
The man touched his right knee with his index finger and yelled: “Ow, that hurts.” Then he touched his left cheek and again yelled: “Ouch! That hurts, too.” Then he touched his right earlobe. “Ow, even that hurts.”
The doctor examined him for a moment before nodding in realisation. “Ah, I thought so,” said the doctor. “You have a sprained finger.”
