Yes Men prank the Man in New Orleans

Kembrew says,
The Yes Men convinced the organizers of a major conference attended by contractors and government officials in charge of rebuilding N.O. that HUD Secretary Alphonso Jackson would attend the conference. Once at the conference, Yes Man Andy Bichlbaum -- posing as Rene Oswin, a fake HUD official -- delivered a speech that asserted that HUD was wrong and that it would not actually demolish perfectly sound low income housing, as it was planning to do. The Yes Men were working with local N.O. activists who have built a tent city around the site that will be destroyed to make way for a gentrified neighborhood.
