The Yes Men, activist impersonators of corporate excess, continue to outdo themselves.  As they get more mainstream coverage, you'd think the press would not be so easily duped by something so clearly fishy-sounding: An announcement by the US Chamber of Commerce that it is reversing its position aganst climate change legislation, and instead embrace environmental issues wholeheartedly.  This one gets even better, as a visibly flustered official from the Chamber of Commerce interrupts the fake press conference to try to set the record straight, leading to a game of the old "No, I'M the real guy -- don't listen to HIM!"
