A guy goes to a doctor and tells him, "I've had these violent migraine headaches for years. I've tried everything, been to innumerable different doctors, but to no avail."
The doctor says "I think I can help you. When I have these headaches I have my wife draw a tub of hot water as hot as I can stand. Then I have her give me a complete massage from head to toe. Finally I take her into the bedroom and have unbridled sex with her. That usually does it for me. Try that for six weeks, then see me again."
Six weeks later the guy comes back, and says, "Doc, that really works...I did what you told me and now I'm pain-free! By the way, Doc, that's a beautiful home you have."
