I remember doing this one years ago. Its an online test that throws various questions at you to try to determine your gender based on the pattern and types of answers. The questions themselves are often goofy and lighthearted. It does require signing up for an account at the site, though, just as a forewarning.
http://community.sparknotes.com/gender/In case you were wondering, it told me I was definitely a woman the first time.

I think it was about 70% sure.
This time it turned up:
It all adds up... we feel 4% certain that you are...
A Woman!
Compared to others...
50% more male than you — 7% like you — 43% more female than you
How do we know? Well, deep down, your gender affects everything about you, from your favorite number to your views on Canada. Many women who took the test think and act just like you, as you can see from the graph above.
Statistically speaking, you are a woman—whether you know it or not.
I guess I'm becoming (more of) a guy? Or the test had gotten smarter with more girly guys taking it. Or it's gotten less accurate with people lying. Still says I'm a woman, though.
