I watch (and enjoy) because,similar to Celebrity Big Brother and similar, I like to see what these so called celebs are really like, how they pretend to be and how they actually are when the mask slips.
I don't care about ostrich anuses (ani) or Kangaroo testicles - we watch it in our house for the reasons given earlier. If that makes us sad, or needing to "get a life" then so be it.
