I'm a pretty funny guy, and I think I'm kind of smart.
With being funny, I think it's a defense mechanism for me and always has been. It's a way for me to steer conversations away from being uncomfortable for me. Many people have told me I'm quick witted, that I come up with stuff on the fly. If I wasn't so introverted, I imagine myself some kind of comic, or at least a hit at parties. I think I understand why most comics actually lead tragic lives and are miserable people. Robin Williams had a very dark side, Chris Farley, Belushi, etc... I think some of that was rooted in self-loathing.
As far as smart, I'm not so much book smart, as I am pop culture references smart and trivia smart and crossword/scrabble smart. Mostly because my constant companion throughout my life has been the TV. 44 years of soaking info in through the tube. People always tell me I need to go on a game show someday... can't, I'm too shy.
