In 1810, a prankster sent 4,000 letters to flood one London address with chimney sweeps, coffins, and the Lord Mayor

Theodore Hook is a historical figure whose eccentricity defined his period. He became known for the Berners Street Hoax of 1810—an undertaking considered arguably the greatest practical joke in history. Hook arranged for dozens of tradesmen, including the Lord Mayor and the Duke of Gloucester, to converge on a single London address for a wager.

The event took place on November 27, 1810. Arrivals began at 5:00 am at 54 Berners Street in Westminster. The line-up commenced with chimney sweeps, followed by coal wagons, bakers with wedding cakes, bootmakers, and undertakers whose presence matched the homeowner's dimensions. The procession continued with forty fishmongers, each carrying cod and lobsters; forty butchers presenting a leg of mutton; and fifty pastry chefs with two thousand five hundred raspberry tarts.

Hook had spent the previous six weeks receiving between 1,000 and 4,000 letters addressed to this location. The assembly also included high-ranking figures: the chairmen of the Bank of England and the East India Company, the Duke of Gloucester, and Joshua Smith, Lord Mayor of London, who arrived "in full regalia."

Hook and his companions observed the sequence from a rented room across the street. Despite police blockades on Berners Street, arrivals persisted until after dark. The final group, arriving at 5:00 pm, consisted of domestic servants who mistook the gathering for job interviews.

Twenty-five years later, Hook summarized his effort in a semi-autobiographical novel: "I am the man — I did it … for originality of thought and design, I do think that was perfect."
