An 8-year-old girl went to her dad, who was working in the yard. She asked
him, "Daddy, what is sex?" The father was surprised that she would ask such a
question, but decides that if she is old enough to ask the question, then she is
old enough to get a straight answer.

He proceeded to tell her all about the "birds and the bees." When he finished
explaining, the little girl was looking at him with her mouth hanging open. The
father asked her, "Why did you ask this question?" The little girl replied, "Mom
told me to tell you that dinner would be ready in just a couple of secs."
