Celebrity is a national drama whose characters' parts and plots are written by the tabloids, gossip columnists, websites and interactive buttons. The famous don't actually have to turn up to their own lives at all.

An American has invented a remote control that will turn off any telly within a 20ft radius. What a marvellous device! What a splendid invention! What a really helpful and improving way of devoting your time to building something that turns off culture. Next week, I'm instigating Burn a Book Week, to encourage even more conversation.

Is it a particularly British trait to so utterly adore truly appalling men, from Tony Hancock through to Steptoe and Alf Garnett, Captain Mainwaring, Rigsby, Del Boy, Victor Meldrew and on to David Brent from The Office. The most deeply adored characters are all simply vile.

Like most parents, I've been stumped by homework, the big questions, such as: 'What is the point of geography - the pilot always knows where we are going?'.
