Canadians and Americans are world-renowned for their love of fast food, so it's no surprise that this prank fooled many on both sides of the border. In 1998, Burger King published an ad in USA Today heralding the launch of an exciting new product: the "Left-Handed Whopper." The burger was described as having the same ingredients as a regular Whopper, but with all the condiments rotated to optimize flavour for leftie customers. The next day Burger King announced that thousands of customers had requested the sandwich, while many others specified that they wished to continue receiving the right-handed product. After all, you don't mess with a classic.
