Vladimir Putin, George W Bush and Peter Mandelson are summoned to heaven by God. God says to them "Go back to your people and let them know that I've decided that the world will end tomorrow".
So Putin goes back to the Kremlin and says "Ok, I've got two bits of bad news. 1 - turns out that God exists. 2 - the world's going to end tomorrow".
Bush heads back to the White House and says "Right, we'll I've got some good news and some bad news. The good news is that God exists. The bad news is that the world's ending tomorrow".
Mandelson goes back to Downing Street and, the wily political spinner that he is, says to Gordon Brown "I've got two bits of good news. 1 - I'm one of the three most important people on the planet. 2 - David Miliband won't be replacing you as Prime Minister!".
