OK, your students have seen all these videos - I know this because Lady Gaga videos have been viewed a billion times online. She is the first artist to reach this mark. So take an hour or so and watch these fifteen videos. Better yet, take the rest of the evening and explore the full Gaga canon that has formed online. There's a lot going on in them, so keep an open mind. They're probably not safe for work. Gaga is a genuine internet phenomenon, and a large part of her huge popularity is the widespread availability of her songs and videos free online.
