On Thursday's Big Brother, Janelle won Head of Household  and thus dodged the possibility of elimination  by coming up with the best answer to a show-related trivia question. Or did she? BB message boards lit up immediately afterward as some fans contended that Janelle changed her numerical answer too late. Oliver Stone-caliber conspiracy theorists even suggested the live broadcast was edited to let her "sneak in" her winning guess. "I can assure you that as a live show, Big Brother is not fixed," insists a CBS rep. "The network and legal [department] reviewed tapes immediately after the competition and Janelle is, in fact, the winner." Well, she's a contestant on Big Brother, so that's "winner" in the loosest interpretation of the word.
