Medieval helpdesk with English subtitles

I love this "medieval helpdesk" video (in Norwegian with English subtitles) not just because it's hilarious (though it is), but also because it's a reminder of something we often forget--that once the now-familiar conventions of the book were as new to people as IM or texting is to those today.

The book, too, is a technology, one that changed how we think in many ways. Ways that we often forget when we're considering how newer media, and how we use them, are shaping society. For instance, did the widespread use of the book after the printing press create introverts? I've been reading Walter Ong on how the book and book culture changed things--I'm sure I'll post commentary on that soon.
