Or something like it...
From the Scholastic site
You have been invited as a guest speaker in a Muggle Studies class at Hogwarts. What would your speech topic be and how would you explain it to witches and wizards?
Hmmm.... my speech would be on 'Non-Magical Communication: The Exhaustive Muggle Way of Staying in the Loop.' I 'spose I would have to do demos. Telephones, cellphones, computers with email.... I must think on this some more.
