Sex In The Dark

There was a couple who just got married. Their sex life is wonderful. But for some reason, everytime they made love, the husband always insisted in shutting off the lights. After 20 years, the wife turned on the lights and found him holding a vibrator. She went ballistic. "You impotent bastard! How could you have lied to me all these years?!" The husband looked her straight in the eyes and calmly said. "I'll explain the toy, you explain the kids."
