Some of Our Favorite Heroes: The Yes Men

Wiki:

The Yes Men are a group of culture jamming activists who practice what they call "identity correction" by pretending to be powerful people and spokespersons for prominent organizations. They create and maintain fake websites similar to ones they want to spoof, and then they accept invitations received on their websites to appear at conferences, symposia, and TV shows. Their newfound, self-proclaimed authority to express the idea that corporations and governmental organizations often act in dehumanizing ways toward the public has met both positively and negatively with political overtones. Elaborate props are sometimes part of the ruse, as shown in their 2003 DVD release The Yes Men.

Their method is often satire: posing as corporate or government spokespeople, they might make shocking denigrating comments about workers and consumers, then point out what appears to be a lack of shock or anger in the response to their prank, with no one realizing the reactionary rhetoric was only a joke. Sometimes, the Yes Men's phony spokesperson makes announcements that represent dream scenarios for the anti-globalization movement or opponents of corporate crime. The result is false news reports of the demise of the WTO, or Dow paying for a Union Carbide cleanup.

The Yes Men have posed as spokespeople for The World Trade Organization, McDonald's, Dow Chemical, and the United States Department of Housing and Urban Development. The two leading members of The Yes Men are known by a number of aliases, most recently, and in film, Andy Bichlbaum and Mike Bonanno. Their real names are Jacques Servin and Igor Vamos, respectively. Servin is an author of experimental fiction, and was known for being the man who inserted images of men kissing in the computer game SimCopter. Vamos is an assistant professor of media arts at Rensselaer Polytechnic Institute, New York. They are assisted by numerous people across the globe.
