Grandpa

           An 8-year-old girl went to her grandfather,
           who was working in the yard and asked him,
           "Grampa, what is sex?"*

           The grandfather was surprised that she would ask
           such a question, but decided that if she's old enough
           to know to ask the question, then she's old enough
           to get a straight answer.  Steeling himself to leave
           nothing out, he proceeded to tell her all about
           human reproduction and the joys and
           responsibilities of intercourse.

           When he finished explaining, the little girl was
           looking 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 this question, honey?"

           The little girl replied, "Grandma says that
           dinner will be ready in just a couple of secs"
