TRY IT: The Wikipedia game.

Best played with two people. Each person comes up with a start and an end point. One person might say “Start at ‘San Diego’ and get to ‘World War II.’” The other person might say, “Start at ‘Jay-Z’ and get to ‘Harvard University.’” Then, both go to Wikipedia and see how quickly they can get from one point to another, using links within the articles. Whoever reaches their point quickest wins. The goal is to make each challenge as difficult as possible, picking two subjects that are vastly different from one another or at least not related in any way.
