About a month ago, I downloaded a nice little $1.99 iPhone App called Sporcle. It's premise was simple: "Hours of Trivia Entertainment!" You pick a topic, and answer as many questions you can in the time alotted. For example, there is a game for all of the powers from 1^1 to 10^10. There are games that test your movie and TV trivia, such as naming all of the surnames of the characters of LOST. There are even the somewhat bizarre games, such as naming all of the Big Mac ingredients.
Fast forward to present-day, and I can tell you what those answers are. I can tell you every Harry Potter spell, I can tell you what the famous British Authors of the last 5 centuries are. I can tell you every fucking book in the Bible, Old Testament and New.
If you want to know information that could possibly be useful, or make you look intellectual in front of friends or the opposite gender, but this little two dollar app.
NOW.
Oh yeah, it's pretty addicting too.
