Who says we're stoopid?

A colleague passed this quiz on to me. The point of the test, or so I thought, was to ascertain that not all Americans were dumb, but I was disappointed when I got a perfect 20 out of 20, and it gave me this result...

If you are American, the only way you got this score is by doing the quiz 50 times, and memorizing the correct answers. You need to approach the world in a less aggressively competitive way and learn to live with your inadequacies, rather than seeking to feel through bigotry and false national pride.

Try it yourself.
