号称“史上最佳剧集”之一的《宋飞正传》，其知名度与受欢迎度毫不逊色于大部分国人熟知的经典喜剧《老友记》（《六人行》）。故事也是以纽约为背景，讲述四个曼哈顿年轻人的故事。故事围绕喜剧演员宋飞展开，主要人物有：自己演自己的杰瑞·宋飞、宋飞的多年老友乔治、宋飞的前女友伊莲，还有宋飞神叨叨的对门邻居克莱默。《宋飞正传》每集故事之间没有关联性，没有贯穿全剧的主题或者主线，主要情节就是讲述四个主人公的日常生活，巧妙地将笑料暗藏其中。编剧从小人物的视角出发，描绘出色的对白语言、演员精湛纯熟的演技以及美式无厘头的插科打诨，是该剧大获成功的原因。《宋飞正传》在播出之后立即得到了评论界和观众的一致好评与喜爱，收视率连年居高，演职员获得数十个重要奖项或提名，Seinfeld和David也从中获得数亿美元的收入。2002年美国权威电视杂志《手指指南》（TV GUIDE）组织的“史上50部最佳剧集”（50 Greatest Shows of All Time）评选中本剧当仁不让名列第一。
