Little Johnny attended a horse auction with his father. He watched as the father moved from horse to horse, running his hands up and down the horses' legs, rump and chest.
After a few minutes, Little Johnny asked, "Pop, why are you doing that?"
His father replied, "Because I'm thinking of buying these horses."
Little Johnny looked worried and said, "Then I think we'd better hurry home right away!"
"Why?" his father asked.
"Because the UPS man stopped by yesterday, and I think he wants to buy Mom!"
