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