Mine is over 9,000. I'm sure someone will come posting he's got an IQ of 250 because a facebook application says so.
Hey now, my score came from successfully clicking on the slowly moving, flashing piggy in a banner ad, not from some silly facebook application!
It was 40,000 by the way.
...But yeah, I've never taken a real IQ test and really don't care to. If it was high it would serve no purpose other than to boost my ego, and if it was low it would just lower my self-confidence. I don't see the point in it.
