Via Ryan, I found 20 Questions To A Better Personality.

Here’s how my personality breaks down (so to speak) (my notes are in red):

Wackiness: 22/100
Rationality: 62/100
Constructiveness: 44/100
Leadership: 50/100

You are a SRDF–Sober Rational Destructive Follower. This makes you a Fountain of Knowledge.

You are cool, analytical, intelligent (I try) and completely unfunny (Hey!). Sometimes you slice through conversation with a cutting observation that causes silence and sidelong glances (more often than I care to admit). You make a strong and lasting impression on everyone you meet, the quality of which depends more on their personality than yours (probably).

You may feel persecuted, as you can become a target for fun (sometimes). Still, you are focused enough on your work and secure enough in your abilities not to worry overly (maybe).

You are productive (maybe) and invaluable to those you work for (I like to think so). You are loyal, steadfast, and conscientious (ditto). Your grooming is impeccable (sometimes). You are in good shape (I’m trying).

You are kind of a tool, but you get things done (probably). You are probably a week away from snapping (Oh yeah).

Addendum, 2004/07/19: this fits me 99%, there is a slight inaccuracy however. We are not necessarily completely unfunny. If we have a sense of humor (I do) it surfaces on the occasion with well-timed, completely dry, very sarcastic, wit. – Chase
