A son 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 the son asked, "Dad, why are you doing that?"

His father replied, "I have to make sure that they are healthy and in good shape before I buy them."

Worried, the boy replied, "Dad, I think the UPS guy wants to buy mom."
