Last night I was out shopping for groceries at my local grocery store when I ran into none other than Randall Munroe, creator of the webcomic XKCD (and, it might be noted, the guy in the grocery store who pushes his cart extra slow and then stops right in the middle of the aisle, so you can’t get over to the candy section!). Before I could muster the courage to challenge him to a cartoon-off, as I knew I must, he had already removed his glove—a long silky stocking of a thing—and lofted it against my cheek, mouthing the words “cartoon off.” The game was on.
