ATLANTA, Georgia (CNN) -- The scene was more reminiscent of a Hollywood production than an elaborate prank by the Punk'd-master himself. A banner with Ashton Kutcher's Twitter name, aplusk, was unfurled Wednesday over the CNN logo at CNN Center. Ashton Kutcher, along with his wife, Demi Moore, dropped by Atlanta, Georgia's CNN Center on Wednesday to fulfill his promise to "ding-dong-ditch" CNN founder Ted Turner's house after winning last April's race to attract 1 million followers on the micro-blogging site Twitter. With the precision of a Hollywood director, Kutcher barked into his two-way radio as his light and sound crews followed with the Twitter entourage hot on their heels and an Internet audience watching on Ustream.
