The show: Big Brother... throw a couple of people who've never met each other together, and put them in a house for three months without any contact with the outside world.
The contestants: Mostly people with nothing better to do with their lives, who do nothing but dress up for the camera's everyday, parading actions which have no moral issues what-so-ever.
Why do people watch? It gives them the opportunity to watch and laugh at the stupidity displayed by the characters on the show everyday.
All together one of the worst... quite possibly THE worst show ever made in television history. The show does nothing but parade the contestants walking around in little clothes, crappy attitude, and absolutely no moral system at all.
Oh.. and if theres any hope of even a score point of 1.1 (couldnt give it anything less than 1 for some reason) ... get a new host.
