One day, a little girl comes running home from school and announces excitedly to her mother: "Today we learned where babies come from!".

Her mother sits the little girl down and asks her fondly: " Now tell me all about it".

The little girl says: " Well, the mommy and daddy take off all their clothes and the daddy's thing sticks up and the mommy takes the thing in her mouth and the thing then explodes. That's where babies come from!"

The little girl's mother leans over and looks her squarely in the eye and says: " No, darling, that's not where babies come from. That's where jewelry comes from".
