The TV commercials for a new chocolate bar called M'azing show people doing amazing things in order to earn a bar of M'azing chocolate. In one commercial a guy balances a washing machine on his jaw. In another one a girl twists her legs all the way around her body in a way that really doesn't look possible. You can see all the ads here (quicktime and wmv format). Someone wrote in to Stuart Elliott's advertising column in the NY Times asking if the movie with the girl doing the thing with her legs was real. Elliott says it is. This is his exact response:

Stuart Elliott: The gymnast in the commercial is really performing what you see on screen, according to the Masterfoods division of Mars in Hackettstown, N.J., which markets the new M'azing line of candy. The spot, called "Mystic Pixie," is indicative of the direction of the campaign, which is to celebrate people whose talents enable them to perform feats that are truly amazing. The performers are, of course, meant to personify the amazing taste of M'azing. The campaign is created by the flagship New York office of BBDO Worldwide, part of the Omnicom Group.
