I was reading recently (I forget why and where) about a kind of protest against overzealous authority figures who weigh down your work day with too many rules and regulations. What you do is follow those rules and instructions very precisely and to the letter, and do nothing more. For instance, if you are asked to clean the toilet, you go and do that, then stay there waiting for further instructions, because you weren't asked to come back when you're done.
Seeing how strict are the rules of the Big Brother house, I wondered how it would start looking if housemates behaved this way. They can't be punished for breaking the rules, but they're not doing anything interesting either, so the show kind of falls apart. The producers can change the rules and give as many instructions as they like, but if the housemates are just doing exactly what they're told and nothing more, it wouldn't be an interesting show for very long.

PS - I am well aware that it is not that interesting a show to begin with.
PPS - I used to watch, but don't bother any more.
