A man and woman had been married over 20 years. The husband always insisted that the lights be off every single time they made love. After 20 years of this, the wife decided she wanted to spice things up. The next time they made love, at the height of passion, she reached over and switched on the lamp sitting on her night stand.
Her husband jumped up and to her surprise she found him holding a large soft vibrator--- "You impotent bastard! How could you betray me all these years?? You better start explaining," she yelled.
Calmly her husband looked at her and said, "I'll explain the toy. You explain the kids."
