And here I was thinking it might be the "Or?"<br/><br/>Because as XKCD notes, "Or" is considerably more entertaining:<br/><br/>(https://imgs.xkcd.com/comics/security.png)<br/><br/>I'm going to go out on a limb here and imagine that "taking 20" is pretty viable for something like trying to code-break (although I guess at that point it's more a question of '20 hours' or '20 days'?)?<br/><br/>EDIT: Andi, I also noted that she looked inside the black-covered book without any holy symbols on it. What's that one seem to be about?
