A sweet little girl runs out to the backyard where her father is working and asks him, "Daddy, what's sex?"

So, her father sits her down and tells her all about the birds and the bees. He tells her about conception, sexual intercourse, sperms and eggs. He tells her about puberty, menstruation, erections and wet-dreams. Then he thinks, what the hell, and goes on to tell her the whole works, thinking that to tell it all is the only way to tell the truth.

The girl is quite awestruck with this sudden influx of bizarre new knowledge. Her father finally asks, "So what made you wish to know about sex?"
