Meet the cast of ''Big Brother 5''
The fifth installment of CBS' ''Big Brother'' (Tuesdays and Saturdays at 9 p.m., Thursdays at 8) is as twisty as a strand of DNA -- appropriate, considering this season's shocks.
As part of what the show dubbing is Project Do Not Assume (yes, that's DNA for short), housemates Jennifer and Michael discover they have the same father (uh, don't worry: there's no hook-ups between the half sibs, as far as we know). Plus, host Julie Chen is teasing a future subplot involving a contestant and his or her identical twin.
Here's our assessment of the latest batch of housemates, who'll while away the days eating sickening amounts of PB&J, lazing around the pool -- and, oh yeah, scheming to win the $500,000 grand prize.
