The girl I was dating at the time (read getting caught making out on people's couches like the uber-jerk I was at that time in high school) had an interest in D&D I think largely due to her dad. The basement of their house was AWESOME. Wall to wall shelves of dad's fantasy paperbacks and game books.
Well, she and some of our other friends wanted to get a game up, but we had no DM... of course, I said I'd do it. What's the big deal? I thought. I had previously played and run a lot of HeroQuest and Dragon Quest games. I really liked THOSE. how hard could it be!?
