How stupid are we?

So, KFC is running this ad about the $10 challenge. The idea they're pitching is that you can get a meal of fried chicken in a bucket (bleargh), mashed potatoes and gravy, and biscuits for only $9.99 and you couldn't make that meal for $9.99. They show this family in a grocery store, buying everything you'd need to make it, including a bag of flour. And lo, the groceries total up to more than $10. Well of course they do, you MORONS. That bag of flour will last you more than one damned meal, as will most everything else in your cart, save the chicken. How stupid do they think we are?!? And are some Americans out there going, "By golly, they're right! Let's go to KFC!"? Because if there are, I may need to move to Canada.
