Ooops
An 8-year-old girl went up to her grandfather, who was working in his shed and asked him, "Grampy, what is sex?”
The grandfather was surprised that she would ask such a question, but decided that if she's old enough to know something then she's old enough to get a straight answer. Steeling himself to leave nothing out, he proceeded to tell her all about the birds and the bees, human reproduction and the joys and responsibilities that go along with it.
When had finished explaining, the little girl looked at him with her mouth hanging open, eyes wide in amazement.
Seeing the look on her face, the grandfather asked her, "Why did you ask, honey?”
The little girl replied, "Well, Granny says that lunch will be ready in a couple of secs.”
