As hilarious as it is perturbing, Jon Ronson's second collection of Guardian journalism, What I Do, is a treat for everyone who has ever suspected themselves to be at the mercy of forces they can barely comprehend.

In part one, read about the time Jon inadvertently made a lewd gesture to a passing fourteen-year-old girl late at night in the lobby of a country-house hotel. And about his burgeoning obsession with a new neighbour who refused to ask him what he did for a living, despite Jon's constant dropping of intriguing hints. And about the embarrassment of being caught recycling small talk at a party.

In part two, read some of Jon's longer stories, which explore manifestations of insanity in the wider world: the tiny town of North Pole, Alaska, where it's Christmas 365 days of the year; behind the scenes at Deal or No Deal, which Jon likens to a cult with Noel Edmonds as its high priest; a meeting with TV hypnotist Paul McKenna, who has joined forces with a self-help guru who once stood trial for murder - but can they cure Jon of his one big phobia?
