I gave it as a Christmas gift two years ago. Picked it up because of the funny title, saw that it was backed up by "science" according to the back cover and bought it... just apologized for the crappy gift to my brother in law.
We were all confused by the colors. I had a little bit of all colors. My mom used to be red but is now more of the other colors... it really is pretty useless.
I still enjoy taking "personality tests" but I try not fooling myself into thinking that MBTI, Strengths Finder, or DiSC says much more about myself than a horoscope would. If anything it might tell me a little bit about how I perceive myself, but that's not how it's sold.
Thanks to VoF for their work!
