Little Johnny attends a horse auction with his father.
He watches his father move from horse to horse,running his hand
up and down the horse's legs and rump and chest.
After a few minutes, Johnny asked' "Dad why are you doing that?"
His father replied, "Because when I'm buying horses, I have to make sure that they are healthy and in good shape before I buy."
Johnny, looked worried, said, "Dad I think the USP guy wants to buy Mom."
