     GBT 中有人编了个东西，迫于最近物价飞涨，生活不易，想拿出去骗点钱花。

但是他们是一群有良知的人，有感于共产主义共享之风太盛，为防止受骗的人太多。想给软件加点保护，

目的

只骗有钱没处花的冤大头。。。

世界要玩完了，

所有的人，善良的，丑恶的；有钱的，贫穷的；幸福的，困苦的；

相爱的，敌视的；单身的，包二奶的；事业有成的，落魄潦倒的；伟大的，渺小的；

聪明的，愚笨的；总统，平民；母亲，孩子；男人，女人；富婆，司机；老板，测试工程师；

赶紧想想吧，做点什么啊，

忏悔，挥霍，施舍，挽留，享受，奋发，激进，退缩。。。。。

 

在此之前，请学好游泳吧，

憋气尤为重要。。。。
