Little Johnny attended a horse auction with his father.

He watched intently as his father moved from horse to horse, running his hands 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, looking worried, said, "Dad, I think the UPS guy wants to buy Mom."
