The American novelist and screenwriter Simon Rich writes the kind of humorous books you dearly wish that editors on this side of the Atlantic would be more frequently brave enough to commission: loose, chaotic collections of essays, united by the vaguest of themes (in this case, children who are thoroughly oblivious to just how good life in the 21st century is for them) whose point, above all, is to raise as many laughs as possible.

While patchier than last year’s The Last Girlfriend on Earth – Guy Walks Into a Bar, for example, is an elongated joke that should perhaps never have left the bar – Spoiled Brats cements his reputation as a James Thurber for the iPhone generation. Best of all are two essays where the 30-year-old Rich pokes fun at his own privileged upbringing: one narrated by the neglected hamster at his prep school, another where his ancestor, a pickle-factory worker, wakes up in the modern world, having been preserved in brine, and proceeds to illustrate just how trifling Rich’s (and by extension 21st-century New York’s) day-to-day problems are. This is the work of a joyous, untrammelled imagination, with a level of self-awareness beyond its years.
