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.

You either get the point of Africa or you don't. What draws me back year after year is that it's like seeing the world with the lid off.

Facts are what pedantic, dull people have instead of opinions.

It's a great historical joke that when the Spanish met the Aztecs, it was a blind date made in serve-you-right heaven. At the time, they were the two most unpleasant cultures in the entire world, and richly deserved each other.
