A young redhead goes into the doctor's office and says that her body hurts whenever she touches it.
"Very rare but not 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. Everywhere she touches makes her scream.
The doctor says, "You're not really a redhead are you?"
"No," she says, "I'm actually blonde."
"I thought so," the doctor says. "Your finger is broken."
