In 1988 during the Summer Olympics I had two friends that worked at the local newspaper inserting the ads into the paper. One night when the press broke down they discovered that every third or fourth McDonalds ad had a winning scratch off coupon for free food. By the time the press started back up they had a huge stack of free food coupons. We ate there every day for months and never paid a penny. I know, I was totally unethical and creepy but I was just a teenager. What teenager isn't unethical and creepy?
