A woman has been married to her husband for ten years, and for all those
ten years her husband insisted on making love in the dark.  No matter how
much she asked him, he would never turn the lights on.

One night she grew tired of this and turned on the light while they were
making love and saw that he was using a dildo on her.

She says, "Honey, how could you do this! All this time you've never told
me. Explain yourself immediately!!"

The husband says, "OK, I'll explain, but first you have to explain the
kids."
