Come on. This is as real as wrestling on TV. The producers told the weekend crew to mix it up or your job is on the line in this low rated show. You can tell what kind of money a TV show is making by the kinds of advertisements it carries.
You might be right in that the producers are happy to see the hosts come out swinging, but my two cents says the animosity between Juliet and Julian is real. In any case, there was no denying the way Phillips played the race card on the Holloway case.
