They say the trick to pulling a fast one is to do something that could, under some circumstances, be believable. That probably does not extend to this guy, who swapped the Walmart price tags on a 42 inch Sony plasma screen, thereby reducing the price from $948 to under five dollars.

Granted, he had the sense to use the self-checkout line, but they snagged him at the door when he showed his receipt.
