Also, another story.
To avoid cover wrinkling, I carry my books around in a OS X box that has a big X in the front (http://tinyurl.com/6hdmoq). So I'm at the bus stop, with the box in my hand, and an elderly lady approaches and asks for time (a normal thing to do for an old lady). And then, as she leaves, she says "What's that, the X Files?", giggles and leaves.

What the hell.
