呵呵，这位是知音啊！ 要能Confuse别人，

就得像那个老奸巨猾的Rumsfled那样说话：
"Reports that say that something hasn't happened are always interesting to me, because as we know, there are known knowns; there are things we know we know. We also know there are known unknowns; that is to say we know there are some things we do not know. But there are also unknown unknowns -- the ones we don't know we don't know."

你听懂他说什么了吗？
