I just can't wait. Soooo looking forward to it.
It's basically a reality show with mainly intelligent people and some that just think they are, all vying for one job. They are split into teams, boys vs girls to start off with and given a task to do and a brief and they have to head off and make some money for Sirrallan, while being watched carefully by his two sidekicks who report back to SR - Nick and Margaret, just brilliant, hardly say anything but when they do it's priceless and their facial expressions are something else.
After the task they have to go back to the board room where SR has all the info on how they did and never beats about the bush in saying it how he sees it however personal. The project manager of the losing team (the one that lost money or made the least) then has to choose two people to be put forward for firing along with themselves. Boardroom scrap commences and one eventually gets fired by Sirrallan.
Usually involves lots of backstabbing, brown nosing and burying the chosen Project Manager to save their own arses and basically their true colours coming out fairly quickly. Generally there'll be one or two genuinely nice candidates who the public tend to support (Raef and Lucinda last year) but they tend to get slaughtered fairly quickly by the vultures/team mates. It's amazing to watch to see the dynamics of the teams and the egos, who's nice, who's nasty, who'll trample and crap all over everyone to save themselves. It's like "narcissists r us". We are usually thoroughly entertained by the idiots, the mentalists and the gits and there is usually much shouting, jeering and cheering at the telly. (or is that just me

)
More here anyway, they have some previous episodes and clips you can have a nosey at.
