One afternoon a little girl excitedly approached her mother, and announced that she had learned where babies come from at school that day. Amused, her mother replied, "Really, sweetie? Why don't you tell me all about it?"
The little girl explained, "Well... OK... the mommy and daddy take off all of their clothes, and the daddy's thing sort of stands up, and the mommy puts it in her mouth, and then it sort of explodes, and that's where babies come from."
Her mom shook her head, leaned over to meet her eye to eye, and said, "Oh, honey, that's sweet, but that's not where babies come from. That's where jewelry comes from."
