MENSA begged me to join them, begged me! I told them clubs weren't my thing, I'm an introvert, but they assured me their club was full of special smart introverts and there was chess and you could bring it up on the internet and people would respect you. That last bit killed it for me, just couldn't see the fun in it.
Sounds like the Diogenes Club. Which was named after me. Because my IQ is so high.
