Courtesy of the great Gordon Tullock, with a nice lesson in Economics thrown in there, as well. The video is well worth a quick viewing, even for those who don't share my love of economics and
Radiohead (the intro music is "Weird Fishes/Arpeggi" from their album In Raibows), as it is quite entertaining. (NB: I will be voting, and I guarantee that I won't like it per se, but as I feel morally compelled to do so, my behavior is perfectly explained by the Utility function described in the video.)
Hat tip to the ever-excellent Alex Tabarrok over at Marginal Revolution.
