MyLaffs Joke #1572
A little boy was walking in the park with his father and came upon two dogs doing it.
"What are they doing?" the boy asked.
The father replied thoughtfully, "Well Son, they are trying to make a puppy."
The next morning, the little boy woke up early and walked into his parents' room only to interrupt them making love.
"Daddy," the boy exclaimed, "What are you doing to Mom?"
The father quickly replied, "Well Son, your mother and I are trying to make a little sister for you."
The boy thought about this for a moment and said, "Dad, turn her over... I think I'd rather have a puppy."
