London, England, April 3, 2007—Kim, Megan, Ellen, and Kitty cadge chocolate from the world's first edible billboard. Perhaps to the chagrin of London parents, U.K. candy retailer Thorntons invited visitors to the Covent Garden area to pick away at the advertisement in anticipation of Easter.

Britain boasts the world's third highest per capita consumption of chocolate, according to a 2006 report by U.K. trade group Food From Britain. According to the BBC, hungry passersby finished off the 860 pounds (390 kilograms) of candy in just three hours.
