1 of 16Big Brother 12
After 11 seasons, we still can't get enough of this Survivor-meets-The Real World show. Contestants live in a camera-rigged house where they back-stab, yell at and sleep with fellow competitors until one of them walks away with $500,000. The premise never changes, but it always delivers grade-A trashy drama.
