Horse Auction

Little Johnny attended a horse auction with his father. He watched as his father moved from horse to horse, running his hands up and down the horse's legs, 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, looking worried said, "Dad, I think the FedEx guy wants to buy Mom."
