During the Cold War, a Russian spy visited the Welsh valleys. He was ordered to find his contact whom – he was told – is called David Jones. When he finds him, the spy should utter the code words “Daffodils are blooming early in Moscow”.
On arrival, the first thing the spy does is to ask a passer-by if he knows David Jones.
“Certainly,” says the passer-by. “That’s me.”
“Ah,” says the spy, “Daffodils are blooming early in Moscow.”
The passer-by looks puzzled for a moment, and then says, “Oh no, that’s not me – that’s Jones the Spy you want!”
