Daddy was taking his young son for a walk in the park when they passed two dogs humping.
When the boy asked his father what was happening, he told him they were making a puppy.
A few days later the little boy caught his mum and dad in the throes of s*x and when he asked them what they were doing, dad replied they were making a baby.
The little boy said, “Well, can you turn mummy over, I’d much rather have a puppy.”
