There was a little boy about 4-5 years old walking down the street with his dad. They came upon two dogs getting it on.

Little Boy: Daddy, Daddy what are they doing?
Dad: Well son they are making a puppy.
Little Boy: Oh ok Daddy.

The two of them return home and eat dinner then the little boy goes to bed. A few hours after he fell asleep he was awakened by a nightmare. He went to his parent’s room to tell them about it. When he walked in he saw his Daddy on top of his Mommy getting it on.

Little Boy: Daddy, Daddy what are you doing to Mommy?
Daddy: Well son we are making you a little brother or sister.
Little Boy: Well Daddy can you roll mommy over I would rather have a puppy.
