There was this couple that was married for 20 years, and EVERY time they had sex the husband always insisted on shutting off the lights. Well, after 20 years the wife had enough and wanted to mix things up a bit and see what was going on all these years. So one night, while they were in the middle of doin it, she turned on the lights. She looked down and saw her husband was using his own motion but holding a 10 inch dildo. "You bastard," she screamed at him, "how could you be lying to me all of these years. Explain yourself!" The husband looks her straight in the eyes and says, calmly, "I'll explain the dildo if you can explain our three kids."
