Two dogs in the Park.

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.”
