Is CNN for real? The headlines on its website — "Minced onions force emergency landing" — cause some to wonder if its Atlanta-based producers aren't having a jape at the expense of news junkies.

As blogger Andy Baio notes, the feature is easily manipulated, allowing users to construct any story they want and get it printed. But why bother making up the news when CNN shows just how much stranger truth is than fiction?
