How I Understood My Mind Is Different From 98% Of Persons in The World

I found a test in StumbleUpon! It was about answering some questions (you can do it here if you don't want to read this post till the end). I had to do some moltiplications and than I had to remember a country with the letter "D".

I'm not very brave in Geography today, so after a while I remembered the only country that beginns with "D" and it was Denmark. After that I had to remember a name of an animal with the last letter of the word. I controlled the mode to write this countryname in a dictionary because I thought the last letter is "C".

My dear God, do you know an animal that beginns with the letter "K"? I could not remember one. So I opened WWF site, "Search by species", passed time to look for at least one animal that's name beginns with the letter"K" and found that there are 3 of these names: Kingsfisher (a bird), Keelback(a snake) and Kiwi. This last is "nearer" to me, I thought, (I watched a doumentary about it) and choose it.

After that I had to remember a fruit that beginns with the last letter of the name of that animal. My animal was Kiwi, so the fruit with the letter"I". Maybe I'm too sleepy today, I thought. I DON'T REMEMBER one fruit that beginns with the letter "I". I even found a list with all the fruits! Here it is:

There is NOT a fruit with letter "I"!!!!! I was disperate and did not know what to do now, so I read the end of the test. And was surprized.

"Are you thinking of a Kangaroo in Denmark eating an Orange? If not for you, you're among the 2% of the population whose minds are different enough to think of something else."

After that I wanted to know where is the trick in this test. And found it. Here: "MULTIPLY that number by 9 . If the number is a 2-digit number, ADD the digits together"
Why?
