Playable Xbox 360's at Wal-Marts

Joystiq is reporting and many are confirming that playable Xbox 360 demos are popping up in various Wal-Marts throughout the country. Setting aside the evil that is Wal-Mart (see the most recent JibJab "Big Box Mart"), I do believe that Allison and I will venture to the Clackamas, OR Wal-Mart today or tomorrow to check it out. Reportedly, playable demos of Call of Duty 2, Kameo, and King Kong are part of the display. What penance will I have to do for stepping into a Wal-Mart? I guess I have to go through my old clothes and give some to Good Will.
