A man and his wife had been married for several years. But every time they get intimate he turns out the lights.
One day the wife gets sick of it and flicks the light on while they are having sex. THe first thing she sees is her husband using a dildo.
Enraged the wife exclaims "You mean to tell me all these years you have been doing this!?"
In the man's defense he replies "Before I answer that I want you to explain our three kids."
