Netflix has a really good documentary now available called "Pepsi, Where's my jet?." It tells the story from the 1990s of a Pepsi point promotion that featured a TV commercial claiming that you could get a Harrier jet for 7,000,000 points. A guy figured out he could by the points for $700,000, got funding from a friend, and tried to claim the jet. When Pepsi blew him off, he sued.
