寓言故事
战国时期，齐国的国君齐宣王喜欢音乐，尤其喜欢听吹竽，手下有300个善于吹竽的乐师。齐宣王喜欢热闹，爱摆排场，总想在人前显示做国君的威严，所以每次听吹竽的时候，总是叫这300个人在一起合奏给他听。
有个名叫南郭的处士听说了齐宣王喜欢听合奏，觉得有机可乘，是个赚钱的好机会，就跑到齐宣王那里去，吹嘘自己说：“大王啊，听过我吹竽的人没有不被感动的，就是鸟兽听了也会翩翩起舞，花草听了也会合着节拍摆动，我愿把我的绝技献给大王。”齐宣王听得高兴，很爽快地收下了他，把他也编进那支300人的吹竽队中。
从这以后，南郭处士就随那300人一块儿合奏给齐宣王听，和大家一样享受着优厚的待遇，心里极为得意。
其实南郭处士他压根儿就不会吹竽。每逢演奏的时候，南郭处士就捧着竽混在队伍中，人家摇晃身体，他也摇晃身体，人家摆头，他也摆头，脸上装出一副动情忘我的样子，看上去比别人吹奏得更投入。南郭处士就这样靠着蒙骗混过了一天又一天，不劳而获地白拿着丰厚的薪水。
但是好景不长，过了几年，爱听竽合奏的齐宣王死了，他的儿子齐湣（mǐn）王继承了王位。齐湣王也爱听吹竽，但他喜欢听独奏。于是齐湣王发布了一道命令，要这300个人轮流来吹竽给他欣赏。南郭处士急得像热锅上的蚂蚁，惶惶不可终日。他想来想去，觉得这次再也混不过去了，只好连夜收拾行李逃走了。
像南郭处士这样不学无术、靠蒙骗混饭吃的人，骗得了一时，骗不了一世。假的就是假的，最终会因逃不过时间的检验而被揭穿伪装。我们想要成功，最好的办法就是勤奋学习，只有练就一身真本领，才能抵挡住一切困难、挫折和考验。
