14. Help feed the world
Meet the only thing on this list ideal for those instances when you are trying to actually give the world something, instead of just reaping the bounty of comped items and services like a cyber-glutton. With Freerice, you can exercise your noggin and help feed hungry humans all over the world, without sparing a dime. The site presents you with a series of questions in subjects like English grammar and basic chemistry, and for every correct answer, the World Food Programme will donate 10 grains of rice to the global cause. You can rack up the grains pretty quickly, though -- and all for a worthwhile cause. It's trivia that can make an actual difference. Unlike Trivial Pursuit, which just tears families apart. Trust me, I haven't spoken to my sister in years. Denise, if you're reading this, please call me.
