A young brunette goes into the doctor's office and says that her body hurts wherever she touches it.
"Impossible," says the doctor. "Show me."
She takes her finger and pushes her elbow and screams in agony. She pushes her knee and screams, pushes her ankle and screams and so it goes on, everywhere she touches makes her scream.
The doctor says, "You're not really a brunette, are you?"
She says, "No, I'm really a blonde."
"I thought so," he says. "Your finger is broken"
