I can still remember how excited I was when my first set of Worldbook Encylopedia's arrived at my childhood home. I was a nerd even at 8 years old. My dad suggested that I read an article a day until I had consumed the whole shelf of leatherette bound tomes, and I would often read myself to sleep with one. (I told you I was a nerd.) Wikipedia does this one better and even has a random page link. So hit that up and surf the Wikipedia for a while. You'll defiantly learn something, and you might even be able to TEACH someone something.
