One night, a woman was curious as to why her husband would only have sex with the lights off. So she decided that the next time they would make love, she would turn on the lights half way through. Later that night, they were making hot passionate love when she turned on the lights. She looked down and found that her husband was using a vibrator. She was furious and said: "How dare you! All these years and you never told me! Explain yourself!" The husband calmly replies: "Okay, I'll explain the toy, you explain the kids........."
