In this week's History of Art & Design II class, I mentioned Ursus Wehrli's book, Tidying Up Art as a commercial example of parody. One of my students (sorry; can't remember who) said that he'd seen a TED talk by Wehrli, so I looked it up, and here it is.
Just in case you have a few minutes to spare, or need a break from studying for midterms.
