Anderson Cooper in a Purple Hat

Omigosh, Anderson Cooper is so cute! This was a great prank by his CNN staffers.

From Yahoo:

During a segment running down recent celebrity news, Sesay was telling Cooper about how "Justin Bieber's being called a brat" by "CSI" star Marg Helgenberger. But instead of the expected shot of the Canadian teen-pop heart-throb, the screen flashed a picture of a young boy in a fuzzy purple Russian-style hat and a similarly hued uniform, replete with silver epaulettes. This was a shot of the boy Cooper. "Wait a minute wait a minute wait a minute," the adult Cooper said. "Where did this picture suddenly materialize from?

"I was pretending to be Wally Norden, the world's youngest bear trainer, on 'To Tell the Truth,' " Bob Stewart's classic American game show, Cooper explained. Sesay tried to get back to the Bieber news, but Cooper interrupted: "I'm not hearing anything, I'm just thinking about people I'm gonna fire," he announced amid a rising chorus of in-studio laughter.
