A man goes to the doctor with a long history of migraine
 headaches.
 
 When the doctor does his history and physical, he discovers that
 his poor patient has had practically every therapy known to man
 for his migraines and STILL no improvement.
 
 "Listen," says the Doc, "I have migraines, too and the advice I'm
 going to give you isn't really anything I learned in medical
 school, but it's advice that I've gotten from my own experience.
 
 When I have a migraine, I go home, get in a nice hot bathtub, and
 soak for a while. Then I have my wife sponge me off with the
 hottest water I can stand, especially around the forehead. This
 helps a little.
 
 Then I get out of the tub, take her into the bedroom, and even if
 my head is killing me, I force myself to have sex with her. Almost
 always, the headache is immediately gone. Now, give it a try, and
 come back and see me in six weeks."
 
 Six weeks later, the patient returns with a big grin. "Doc! I took
 your advice and it works! It REALLY WORKS! I've had migraines for
 17 years and this is the FIRST time anyone has ever helped me!"
 
 "Well," says the physician, "I'm glad I could help."
 
 "By the way, Doc," the patient adds, "You have a REALLY nice
 house."
