So, the first time I tried it, I chose to answer only 18 of the 45 questions and I found out that I was Saddam Houssein!
That just wouldn't do, so I took the test again. Instead this time I answered all of the 45 questions and came out with Abe Lincoln. Now that's more like it:) Apparently the more questions you answer the more accurate your test results will be because they have more information to gauge from. Works for me!
