The bear and the fax 熊和狐狸（中英）

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.”

A hypocrite deceives no one but himself.

有一只熊曾经大肆鼓吹自己多么仁慈，与其它动物相比，自己是多么文雅。（其实，绝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！”

骗子只会掩耳盗铃似的欺骗自己。
