老布什有一天突然想放松一下，于是打电话给Dan Quale问他：“Who is your father's son but not your brother?" Dan Quale 说：“Mr. President, I think that is a very interesting question, I will investigate it and get back to you." 然后他打电话给国务卿James Baker：“Jim, I got a great question for you, who is your father's son but not your brother?" Baker 说：“I guess it's me." Dan Quale 很高兴， 说"Very good answer, Jim!" 之后他立刻给布什打电话：“Mr. President, I've got the answer to your question, it is James Baker!" ：）
