There was this couple that had been married for 20 years. Every time
they made love the husband always insisted on shutting off the
light.

Well, after 20 years the wife felt this was ridiculous. She figured she
would break him out of this crazy habit. So one night, while they were
in the middle of a wild, screaming, romantic session, she turned on the
lights. She looked down. and saw her husband was holding a
battery-operated leisure device... a vibrator! Soft, wonderful and
larger than a real one.

She went completely ballistic. "You impotent bastard," She screamed at
him, "how could you be lying to me all of these years? You better
explain yourself!"

The husband looks her straight in the eyes and says calmly:
"I'll explain the toy . . . you explain the kids."
