WHAT THE HECK?!?!? Austin powers doesn't have good social skills AT ALL! He has poor grooming, goes for the flashy outlandish stuff.(to gain attention). Uses that stupid pump and platform shoes to compensate for perceived problems. Is overconfident and blatent in weak areas, like thinking women are men. etc...
If not for the fact that so many were so outlandish, one would think any apparent popularity was contrived. Frankly... If I has less pride and intelligence, I could have done everything AP did. If I was in as showy a time and people were so hard up, as in AP, I might even have had better luck than he appear to(without the stupid motions and effect to cause the fembots to blow up, etc...). Frankly, for the fembots, I liked the bionic series concept better.
By contrast, I have good grooming, am conservative/laid back, don't have any perceived problems of that nature. I tend to be shy, and not so blatent.
So AP got lucky because he was in so many peoples faces, etc... I am often not even really seen.
I could go into bars, wear flashy jewelry, say the silly pickup lines.(I actually kind of like the double entendre of "If I said you had a beautiful body, would you hold it against me?"!), and try to make out with everything with long hair. But, frankly, all that is 180 degrees from where I am at.
BTW Out of the three, I think that, out of the pictures you showed, the rainman one looked more autistic. The idea of not caring about looks, being disinterested, and having something to care for needs that you seem most concerned for, are all typical autistic features. I am a little less obvious in all three ways, but sometimes look similar.
