I have an idea for a programme. It would be a bit like The Jeremy Kyle Show but the guests on it would be posh people only.

The first guests would be that boozy couple off Gogglebox who could talk about their love of the drink.

Then there would be Prince Charles from London who could talk about his dependence on the state.

And then there would be the Fulford family from Devon who would come on and squabble and swear and take swipes at each other.

You may remember the Fulfords from the Channel 4 documentary they featured in 10 years ago.

Called The F***king Fulfords, it followed the patriarch Francis Fulford as he attempted to save his crumbling house in Devon.

Ten years on, the new documentary, Life Is Toff (Tuesday, BBC Three, 10pm), reveals that Francis himself is now crumbling in much the same way as the house: his teeth are like broken slabstones, his hair white, like snow on the leaking roof.

Otherwise, family life is pretty much the same, with the house and estate ringing to the same old sounds: the squeak of wellies on waxed floors, the bang of guns going off and various types of wildlife dying, and, of course, the sound of the coarsest words in the English language being uttered over and over again in the most perfect, beautiful, aristocratic accents.

The big difference is that the four children are all grown up, although much of their behaviour continues to be horrible and questionable.

But what's most striking about it all is that if the Fulfords were a working-class family, they would end up on the real Jeremy Kyle Show and be howled at by the audience.

But because the Fulfords are posh, the bad behaviour is treated as eccentric, colourful and amusing. Is this OK? Is it double standards?

Possibly, but what's also unavoidable is the fact that as a family, the Fulfords are mysteriously likeable, possibly because they possess a suspicion of rules and procedure and a desire to crack on with minimum whinging.

But it could also be because in most ways they are pretty much the same as the rest of us: they argue, they bicker, dad tries to keep control and sometimes succeeds.

What Life Is Toff does in showing all of this is it confirms some of the clichés about the aristocracy but subverts most of them.

Revolutions and social change depend on us believing that those at the top deserve to be overthrown because they are completely different. The truth is most toffs are pretty much the same as the rest of us.
