Back in March, Dr. Pepper offered a free drink to every American if rock band Guns N' Roses released its new album, Chinese Democracy, by the end of the year. The general consensus among music fans was that it was a risk-free offer for Dr. Pepper, as GNR had been working on the album since 1994 and had already missed several promised release dates.
Or tried to. Sort of. The company offered a free coupon for a 20 oz. Dr. Pepper to anyone who registered on the company's website on November 23. Guns N' Roses issued a press release urging fans and other Americans to register -- and enough listened that they managed to overwhelm Dr. Pepper's servers, resulting in error messages or blank pages that refused to load.
