The Yes Men — self-described “gonzo political activists” disguised as corporate toadies — took on the U.S. Chamber of Commerce Monday. As the chamber, they issued a news release and then staged a news conference at the National Press Club in Washington DC, announcing that the chamber had seen the light and decided to throw its weight behind climate change legislation it long opposed. “Mother Nature means business, and we do too.”

At the close of the conference, confusion ensues — and some will say hilarity reigns — when a genuine chamber spokesman barrels in to denounce the fraud.

Here’s a link to a video assortment, including the Fox Business Network’s credulous coverage of the chamber’s new position coming to a screeching halt.
