The ghost of Stalin visits Gordon Brown in a dream. Brown takes advantage of the apparition and asks Stalin for some advice. "The UK economy is on the edge of total meltdown Comrade Stalin, what should I do?"
Stalin takes a puff on his pipe and says; "I would advise two measures; first, round up all the bankers in the UK and shoot them. Second, paint Downing Street blue"
"Why should I paint Downing Street blue?" Brown asks.
"Ha, that is what I thought; the first measure needs no explanation".
