I don't understand.. where did the context for an etch-a-sketch getting mailed come from? Why does every day of travel decrease the chances of it getting to its destination?

I have to know.. :)

*EDIT: ahhh, non-linear commenting! I went to the wired article from the other comment and found what you're referring to. I thought maybe they mailed it with a picture... they mailed it with an address?! that's one hell of a stress test.
