Thank God for Britain's class system.
Without those chinless toffs at the top, the bowler-hatted money-grubbing middle classes in the centre and the lovable working classes doffing their lovable cloth caps at the bottom, my television entertainment choices down the years would be so much the poorer.
Some of my favourite TV series - to name three, Brideshead Revisited, The Good Life, Auf Wiedersehen Pet - have been saturated in British class consciousness, comment, clashes and observation. Even from the other side of the planet, you cannot help but understand that there is us, there is them and there is the other lot.
Of the three classes, I have to say (sorry Auf Pet's Oz and Barry and The Good Life's Tom and Barbara) that I find the toffs vastly more entertaining than the rest (only on TV, of course). This is why I approached the first episode of The Aristocrats (7.30pm, Fridays, Prime) with such relish.
This is not a class-conscious comedy. Nor is it a class-conscious drama. It is a class-conscious documentary. Though the series' first part, The Aristocrats: Blenheim Palace, about the 11th Duke of Marlborough, his heir and their vast country pile, was certainly a documentary with laughs and plenty of drama.
