We’ve mentioned cockeyed.com before (right here in fact), but if you’ve never stopped by that site before, you should. It’s quite entertaining.
They have a really great section of pranks that always tend towards the absurd.
This one in particular involves fake magnetic product labels for nonexistent oddities like “STUFFED ZEBRA”, “DVD HELMET”, and “INFANT SKULL REPLICA”. Several people were involved in this one, and there are many pictures of the results.
Admin note: Unfortunately, looks like the prank has been taken down from the site. I highly recommend checking out their other pranks, however.
