A woman was very despondent over not having sex in quite some time. She was becoming agitated and worried that she might never find a mate. In hopes of finding a solution to her problem, she decided that it was time to see a doctor. Looking through the phone book, she came upon a Chinese sex therapist named Dr. Chang.
When the woman arrived, she told the doctor her symptoms, and he said, "Take off all your crothes and you crawl real fass away from me across the froor".
She crawled to the other side of the room and Dr. Chang said, "Now...you crawl real fass back to me", and she did.
Dr. Chang shook his head and said, "you haf real bad case of Zachary Disease....worse case I ever see! That why you haf sex probrem". The woman was completely confused and asked the doctor exactly what Zachary Disease was and he replied, "Zachary Disease....that your face look ZACHARY like your arse!"
