The Infamous Berners Street Hoax: Brace yourselves, pranksters and flash mobbers, because you all look downright pedestrian when compared to Theodore Hook. For no purpose other than his own amusement, Hook sent out thousands of letters requesting services at the address of 54 Berners Street in London. All day, the unsuspecting residents had to send away chimney sweeps, wedding cakes, over a dozen piano deliveries, priests, lawyers, dignitaries... It was reported that Berners Street eventually became so congested with chaos that every available police officer was sent to try to disperse the crowd. All the while, Theodore Hook calmly sat across the street, letting the insanity entertain him all day.
