Wonk, lol. I want my title to be wonk! Wonk is so much more unusual and interesting (and silly!) than Professor or Doctor or Esquire or something all stodgy and formal like that.
Dr. Smiling III, Professor Emeritus, DDS, CRNA, Esq; and wonk-at-large, lol.
Oooh! I like it. I feel more successful already.
