In the video clip above, a producer for The O'Reilly Factor ambushed Rosie O'Donnell to accuse her of being a 9/11 conspiracy theorist... at her own book signing. The juicy stuff begins at 2:15.

Of course there's the fact that ever since Rosie went off The View, Bill O'Reilly has virtually given O'Donnell a new tv platform. The media's funny that way, kids.
