Little Tommy is attending 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 of watching, Tommy asked his father: "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 them." Tommy gets a worried look on his face and says to his dad: "Dad, I think the Fedex guy wants to buy mom."
