I saw this local TV news report recently in which a woman alleges that the iPod she bought from the Honolulu Wal*Mart actually didn't have an iPod in the box. What she displayed to the camera looked like plastic wrapped dog food. Sites like Gizmodo and Engadget picked the story up and eventually updated it saying an internal Wal*Mart investigation indicates a former employee made the switch to that, and other iPod boxes.
So, to all you kids out there who got a lump of meat in your stocking for Christmas, it's not because you were naughty.
