A promotional game at McDonald's designed to draw the most number of people to McDonald's at the lowest possible cost to the giant food chain.

On each box of large fries there is a Who Wants to be a Millionaire? question that is revealed when you rub off the covering. Next, you rub off one the correct answer. If you select the correct answer, you get to rub off one prize box out of six. Typically, five of the prizes are free small items at McDonald's and one is $1 in prize money. You could win up to $1,000,000 from this game.

So, the next time you are at McDonald's and you buy a $5.00 meal, you have a 1/6 chance of getting $1.00 back, if you know what the small cavities in which individual strands of hair grow are called. . . . What a fun game!
