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