Book excerpt: Juvenile, profane, and timeless, Fuck This Book collects images of real public signs that have been mischieveously altered by stickers bearing the most expressive of all four-letter words. Addictively hilarious, the results show a world persuasively transformed. Please Don't Fuck the Pigeons, indeed. What happens if one triggers the Automatic Sprinkler Fuck Off Valve? And is it any wonder The Fuck Depot is so popular? All photographs are unretouchedthe result of countless hours on the hunt for the almost perfect sign, in need of just the slightest improvement. This is not social commentary. There is no message. It's not meant to offend, exploit, or embarrass anyone. All real stickers. All real signs. All in fun.
