Little Johnny is watching his parents making love in the bedroom through the key hole.
In some minutes his father asks mother:
"Dear, who do you want now, a girl or a boy?"
"We already have a boy, let it be girl now".
Some minutes later father goes out of the room, Little Johnny wears off his trousers, turns so that his ass faces his father and says:
"Dad, and I want a sword, a bike and a box of color-pens!"
