A man goes to his doctor complaining about migraines. His doctor tells him, "I also suffer from the same ailment. Every time I get one, I give my wife oral sex. When she has an orgasm, she tightens her legs around my head which gets rid of the pain. You should try it sometime." Two weeks later on a return visit, the patient tells his doctor, "Your suggestion worked and I'd like to tell you that you have a very nice house."
