With the fumigation circus tent removed from the Big Brother house on the Radford lot, every stubborn germ, virus, and parasite from the last batch of contestants effectively snuffed, we're now ready for another round of the hit CBS reality series.

Big Brother: 'Til Death Do You Part pits eight teams of two against one another: all couples. And by that we mean, sex-having couples.
