A boy went to a horse auction with his father.He noticed his dad as the father ran his hands over the legs,chest,rump,and various places on different horses.The son asked his dad why he was checking out the horse in that manner. "Son , I do this to see if that is a horse I would like to buy." The son got a very worried look on his face. His father saw the look on his face , and said " Son , what's wrong ?" "DAd , I think maybe the UPS man wants to buy Mom."
