An 8-year-old girl went outside to find her dad, who was working in the yard. She asked him, "Daddy, what is sex¹?"

The father was surprised that she would ask such a question, but decided² that if she was old enough to ask the question, then she was probably old enough to get a straight answer.

He proceeded³ 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, "So, why did you ask?"

The little girl replied, "Mom told me to tell you that dinner will be ready in just a couple of secs."
