Douglas Hofstadter (author of "Godel, Escher, Bach") ran an interesting contest once: the prize was some huge amount of (virtual) money, and you could enter as often as you wanted (to enter, you sent in your name, along with how many times you wanted to enter). The catch was that the actual amount awarded was the intial prize money, divided by the total number of entries. So if you wanted to win, it's easy: send in your name with a huge number, like a googol or a googolplex. But the more times you enter, the smaller the award. The way to maximize the amount of money awarded is to make sure people enter as few times as possible; but as soon as one guy enters a huge number of times, those who enter a small number of times are doubly screwed, because both their chances and the winnings are dramatically reduced.
