Dad showed me this today - apparently he uses it as an exercise with his legal studies kids. (I got 16 if anybody is interested - can you help me out with questions 5, 7, 8, 9, 10, 12, 13, 14, 16, 17, 19, 20, 22, 24, 28, 30, 31? Gosh, that's a huge list there that I didn't get...)
Here's that link again.
