Sporacle - games and quizzes

About Sporacle: "Originally begun as a sports pick'em site, Sporcle changed directions with the response to the first quiz, U.S. Presidents. As avid crossword, Jeopardy! and trivia fans, we created that original quiz not only to test knowledge, but also as a way to learn a piece of information that seemed to come up again and again. Since then, Sporcle has continued to create quizzes for entertainment, memory and diversion (don't worry, we won't tell your boss)."
