That reminds me.
A father and son were out for a walk together when they came across two dogs mating, the boy asks "dad what are they doing?" Dad replies "they are making puppies".
A couple of nights later the son disturbs his parents mid coitus, and asks "dad what are you doing?" Dad answers "we are making a baby".
Son promtly says................."turn mum over I'd rather have puppies".....
A Veeeerrrryyyyy old joke (from my teens)
