The Fox affiliate in Raleigh-Durham, N.C., is refusing to air tonight's apocalyptic reality special Who's Your Daddy. Instead, WRAZ-TV will broadcast the documentary I Have Roots and Branches: Personal Reflections on Adoption. Fox maintains that the show — in which an adoptee tries to figure out who her father is among a group of eight men — has been "thoroughly vetted" by its standards and practices department. And let's face it, that's one prudish group.
