There Is No Such Thing As

From SeinLanguage (1993), Seinfeld's first book, a collection of observational comedy essays drawn from his standup act. The line targets the idealised notion of "family entertainment" — the idea that there is a single category of fun that simultaneously satisfies every age group. It is a concise example of Seinfeld's method: identify an unexamined social cliché, expose its absurdity in a single sentence, and move on.
