I can't really hold a candle to most people in this thread, but I'll go on regardless:
1) I once spent an entire bored, empty Sunday rehearsing and recording a voiceover of Kwaan's steel plate. With the original lines
and Ruin-corrupted lines.
2) I also figured out that Clod is Arsteel, but meh.
3) I know far too much stuff about the expanded BS universe than a Californian high school student should. I've never even been to Utah, let alone BYU, though this will probably be remedied when I start doing college visits this summer.
4) I once sent the Warbreaker PDF to no less than eleven people I had made the recommendation to. Nine of those asked where they could buy
Elantris within a week, and are now fervently awaiting ToW and WoK.
5) I convinced my sophomore English teacher that a creative writing class would be a really neat thing for the school to have - based on the sort of work creative writing can produce, like, hey,
Mistborn.
6) I have most, if not every, unpublished work EUOL has put up for download saved on their own USB stick, should those download links ever stop working.
7) Out of sheer boredom, I once tried to figure out why each metal corresponded to its particular ability. I got some pretty beastly explanations written up, but they're all probably way off the mark.
I just realized an eight and a closed parenthesis make that little emoticon with the sunglasses.
You used that to make sure you got to sixteen
Of course. The number of universal power ensures his victory. : p
