A woman suffers from a painfull headache and tries a new doctor. He tells her tu rub her temples and repeat "I have no headache, I have no headache, I have no..." and amazingly enough, the headache desapeares after 5 min. She then thinks, that the doctor might be able to heal her husband who suffers from virility problems. The man visits the doctor and when he comes home, he just said that he needed 5 min for himself in the bedroom. Afterwards, he had no problems at all...

This goes on perfectly for quite some time until the wife gets curious and listens on the bedroom door. She hears the man repeat: "This is not my wife, this is no..."
