Have you ever spent hours staring off into nothing, wondering if you might secretly be a genius? If so, there’s a good chance that you’re either a genius or….well, I’ll just let you believe what you want. However, if you’re curious enough that you’d like to have your intelligence calculated by an impartial third party, this IQ Test Gift Box might be just what you’re looking for.

This box contains everything you need to test your IQ. This includes a book explaining the test, some practice quizzes, and the test itself. Once you’ve taken the plunge and cracked open the test, don’t bother cheating, unless you’re happy with an inaccurate score. After you’ve completely exhausted your brain and completed the test, you’ll mail it off (envelope and postage are included) and await your results. Within a month, you should have a certificate to display your genius-level IQ. Of course, if the score isn’t so high, you can always just throw it away, and not tell anyone. The test is more for fun than anything, and only sets you back $20.
