Here's another gem I found on the Internet a few years back. Not sure who to credit other than someone calling themselves "Specklet."
Here's the deal. Basically, the idea is to come up with a list of four random items that could be found at a large retail store -- WalMart, for example. The four items are innocuous in and of themselves, but in combination they would cause the cashier to freak out, or at the very least make them wonder "What in the hell is going on here?!"
Come up with your own list and be sure to leave it in the "Comments" section!
