it's my life

The teacher of a first grade class gives instructions to the little boys on how to go to the bathroom.
The teacher tells them the following:
One - unzip your zipper
Two - pull your pecker out
Three - stroke the skin back
Four - take a pee
Five - stroke the skin forward
Six - put it away and zip up the zipper
So the boys go to do their thing and return a few minutes later. The teacher asks, "Where is Little Johnny?"
One of the boys replies "He is still in the bathroom."
The teacher goes down the hall to the boy's restroom and hears Little Johnny "Three, Five, Three, Five, Three, Five............"
