A four-year-old
boy asked his friend what a penis was. His friend's response was that he did not
know and he would ask his dad.
That evening the second boy asked his dad. His dad gladly exposed himself to his
son and with his penis in hand said, "Son this is a penis. In fact, if you take
a good look you will see this is a perfect penis."
The next day the second five year old boy met the first five year old boy and
called him behind a hedge.
The boy exposed himself and said, "This is a penis. In fact, if it were three
inches shorter it would be a perfect penis!"

A little girl runs
out to the backyard where her father is working, and asks him, "Daddy, what's
sex?"
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 goes on to tell
her about puberty, menstruation, erections, wet-dreams...and he thinks, what the
hell, and goes on to tell her the works.
He covers a wide and varied assortment of sub topics and by the time he's finished,
his daughter is somewhat awestruck with this sudden influx of bizarre new knowledge.
Her father finally asks: "So what did you want to know about sex for?"
"Oh, mommy said to tell you lunch would be ready in a couple of secs..."
