My TiVo information for Friday shows the same thing that Lani posted -- allergist and near-death experiences -- plus tummy tucks (woo hoo!).
It may be that those topics comprised the program that was originally planned for that hour -- but that when the GMA segment appeared, the producers of "The Doctors" jumped on a hot topic (oral sex! oral cancer!) and put something together but didn't send out changes for the cable/TiVo guides. It sounds from what Teresa said a couple of pages ago that she was already in contact with the producers, so perhaps they just hurried up their plans.
