This Joke Hurts

A brunette goes to the doctor and says, "Everywhere I touch it hurts." He asks "What do you mean?" So she showed him what she meant. She touched her knee and said "Ouch!" Then she touched her chest and said, "Ouch!" Then her shoulder, "Ouch!"
The doctor looks at her and asks, "Your really blonde, aren''t you?" She replies "Yes, as a matter of fact I am. How did you guess?" Doctor says, "Well your finger is broken."
