这部剧是08年下半年冒出来好得出人意外的爆笑小喜剧。本来作者想拍个电视剧，但找不到真人演出，又找不到动画师帮他画，于是就自己摸索著用动画软体做了个短片，然后拿去参展，竟然被HBO看上，就此搬上萤幕，成为继Flight of the Conchords后，HBO又一最新喜剧杰作。本剧围绕主人公TIM的工作生活展开，讲述了这个囧男每天被同事调侃，被女友折腾，被朋友涮锅的种种窘事。整集25分钟的动画，虽说没有笑的前仰后合，不过一直是让人欲笑还抑之的状态。虽然画面很简单，甚至可以用简陋来形容，不过精彩诙谐的对白完全弥补了画面的缺憾，甚至使原本简单的画面更透出一股灵气。更加值得一提的是，本剧的配音演员口齿清晰，发音纯正，语速虽然快，不过用词简单，是难得的学习口语的优秀教材。不过先提一下，毕竟是成人动画，所以有些段子还是有点颜色的，不要把它想象成PG或者是G级别的动画。

100,000 Yuan Zhang Dongqing [Investigation] Hongte Precision's 100-fold Increase: Group Loan Network and Mysterious Funds Behind It (Has Been Off Line)
The fundamental way to put an end to waste is to make the quantity of production consistent with the quantity of sales. If the production is arranged from the front process to the back process according to the traditional processing sequence, the higher the production efficiency of the process, if its rhythm is not suitable for the back process, the more waste of manufacturing surplus will be generated. Therefore, JIT production reverses the traditional way of transferring parts from front to back, and puts forward the order requirements from the back process to the front process according to the order method. The front process only provides the necessary products in the necessary quantity when necessary. Users can supply as much as they need, thus realizing "zero inventory" and not occupying working capital. Commodities that users do not need will not be produced, which can avoid overstock, obsolescence and deterioration of commodities, and can also avoid the costs of loading and unloading, handling and inventory.
