A husband always insisted on making love to his wife in the dark.
After 20 years, his wife decided she'd had enough of this and decided to turn on a light during one of their sex romps. She found him holding a huge vibrator.
She immediately went ballistic, screaming, "You impotent bastard! How could you lie to me all these years?"
Her husband looked her straight in the eyes and calmly retorted, "I'll explain the toy, you explain the kids....."
