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。
