Charlie and the Chocolate Factory

Charlie and the Chocolate Factory was a novel whose plot involved the protagonist getting a winning card and gaining entrance to something when he least expected it. Both Rose Tyler and the Ninth Doctor thought this was similar to the Percy the Porcupine promotion — every time someone bought something downtown, they got a scratchcard. If they got the right number, they could collect their prize. When Rose took her chances, she thought of Charlie: "When you're waiting, hoping, desperate to win, you never do. But then, out of the blue, you get another chance. And that's the one. That's how it works." (PROSE: Winner Takes All)
