The Conversation: David on Demand Obeys Twitter Commands

VIDEO: See just how far one man will take a Twitter

Remember "The Truman Show," where Jim Carrey played a character whose life was broadcast to the world? Truth became stranger than fiction for David Perez, who willingly submitted himself to that same kind of scrutiny and even took it step further in the Twitter age.

Perez, 29, is an ad man who wanted to attend the International Advertising Festival in Cannes, France. He managed to convince his agency, Leo Burnett, to send him, on an unusual condition: that he would broadcast his life live online and do anything people tell him to do via Twitter.

So far, Perez has followed some tough instructions -- he got a tatoo with the Twitter fail whale, poured wine in his lap, and demonstrated pole dancing for two young women.
