A hypocrite deceives no one but himself 骗子只会掩耳盗铃似的欺骗自己。
A Bear was once bragging about his generous feelings, and saying how refined he was compared with other animals. (There is ,in fact, a tradition that a Bear will never touch a dead body.) A fox, who heard him talking in this strain, smiled and said, "My friend, when you are hungry, I only wish you would confine your attention to the dead and leave the living alone."
 
参考译文：
有一只熊曾经大肆鼓吹自己多么仁慈，与其他动物相比，自己是多么文雅。（其实不碰死人是熊的一贯传统。）一只狐狸听到这些话，面带微笑地对熊说：“我的朋友，当你饥饿难耐时，我希望你也能将注意力集中在死人身上，不再吃活人了！”
