A father and son were walking down the street one day and they saw two dogs having sex. The son asked Dad, what are those dogs doing? The dad says son, they are making a puppy. About 2 weeks later the son walks in on the dad and mom having sex in their bedroom. Later the son asks his dad, what were you and Mommy doing? The dad says well son, we were making a baby. The son says next time turn mommy over. I'd rather have a puppy.
