Hypocristics

I don't teach HEL (History of the English Language) anymore since we hired a Medievalist here at our tiny little U, but finding this sort of thing (over at Language Log) makes me long for the days when I did.

Back when I did teach the class, I would struggle to explain what hypocristics where, and how Australians loved to do them, and why they were so cool.  If I still taught the class, I could just load up YouTube and set this commercial running.
