Teaching the Renaissance

Isn't it time we had some posts of amusing stories about teaching? Something like this. I would do it myself, but, you know, there's the whole "I don't teach" thing. Then there's this great administrative story. I could help out with that sort of thing, since even without teaching, one can still be involved with one's department. But not when one is out of town. So, I'll have to rely on the rest of you for good tales, with the names and significant revealing details suitably changed to protect the innocent (i.e., us). Here's a classic told to me by a friend who was teaching a big intro lecture class. They were reading Paul Auster's City of Glass, in which, near the beginning, the main character receives a phone call from someone asking, "Is this Paul Auster?" After class, the following exchange took place: Student: Did he [Auster], like, mean to do that? Prof: Are you asking me if he knows his own name?
