Hmmm... this could be a tough one:
I joined a comic book message board because I wanted to tell everyone my theory about a particular mystery.
I wrote review of GI Joe comics on that message board - in character - hoping to get noticed.
I got noticed and wrote for that site for awhile before helping to start Panelsonpages.com
The highlight of most weeks for me is Tuesday night, when I get to talk to my friends about comic books and other nerdy shit online for other people to hear.
That first message board? I totally met an amazing girl there that I became friends with and am now dating. I dressed as "Sears Catalog Destro" for my first cosplay because she wanted to go as the Baroness.
I talked to Batman. He called me Canadian.
I wrote a backstory for my character in Oblivion, including a song that would've been sung about her.
I was so good at Geometry that while the teacher was teaching class, I was translating the Lumberjack song to French, and I still remember some of it to this day:
Je suis un bucheron et je suis d'accord
Je doit tous le soir et je travail tous le jour.
Je coute les arbres, je mange ma dejeuner,
Je vais au w.c.
Sur Mercredi je vais faire mes achats
Et mange petit pain au beurre pour thé.
