If you watch just one episode of Big Brother 5 this summer, tonight's installment should be it. After being duped for five weeks, the housemates will finally learn the season's big twist: that identical twins Adria and Natalie have been switching in and out of the house pretending to be one person. Clearly, the only way the show can top this stunt is to allow preening ape-man Jase to marry his beloved. (And by "his beloved," we mean his own reflection, not monkey-boy sidekick Scott.)
