When Sarah Palin retrofits a massive bus, announces a nationwide tour on incredibly short notice, and then proceeds to use the entire thing as an excuse to fuck with the people covering her, and she does absolutely nothing except fuck with said reporters, we learn a valuable lesson: stop covering Sarah Palin. 

She set up an entire bus tour to serve as a proxy for her to complain about the fact that the media showed up to cover her being on the bus tour she wanted to use to get her message out.  Through the media.  This is impressively meta.
