There's the joke about the Soviet sleeper agent planted in a small Welsh village. Many years pass without contact, so the Russians send an agent to the village to make contact with him. But the only information the contact has is the sleeper's name; so he goes to the first local he meets and asks after Mr. Jones.
"Do you be wantin' Jones the Baker?" the villager replies, "Or Jones the Mechanic? Or Jones the Barber?"
The contact discovers to his dismay that it seems half the village is named Jones. So finally he describes what the sleeper agent looks like.
"Oh!" the villager says; "You'll be wantin' Jones the spy!"
