Another Chance to Win a Free Copy of SuperFreakonomics

Yesterday, we ran a contest to give away five copies of the new paperback edition of SuperFreakonomics (which can be bought on Amazon and elsewhere). There were more than 640 entries! Thanks for all the support, and for betraying your thirst for free stuff.
So let’s have another contest right now. Last week, when we asked the best way to give away books, your second preference was “really hard contests on blog.” Okay then. But instead of having a quiz here on the blog, we’ve put it on our new Facebook page. So go ahead and “like” our page (if indeed you like it), and try your hand at the quiz. We’ll send a free SuperFreakonomics paperback to the first five people who receive perfect scores.  (The tricky part is that you’ll do much better on the quiz if you’ve read the book but hey, the world’s not perfect is it?) Good luck!
