This is a drawing of me in my natural habitat. I DM a 3.5 edition D&D group (I am a mega geek), its even set in a world I created. I find myself saying things like, "Why did you throw the orphan?" And, "What, are you going to widdle a listening cone out of bugs?" Also, the all time number one used saying, "Are you sure you want to do that?" Add the confused look, throw in, "This isn't WoW..." And that's about it. I'm an excellent storyteller (I am a ST I run White Wolf games to, and I play Rifts. I am such a nerd I should wedgie myself).
