There was this couple…

There was this couple who always had sex for twenty years with the light off.
So one night the wife says lets have sex with the light on. The husband says “tomorrow night honey”.
That night the wife turns the light on and sees her husband using a cucumber to pleasure her.
she screams “You’ve been using that thing for twenty years, explain it to me.”
So the husband says “I will as soon as you explain how we have 4 children!!!!”
