Ah well
French President: "I have ten mistresses. Apparently I married one of them, but which? I don't know."
American President: "I have ten heads of executive agencies. Apparently one of them works for the KGB but which? Nobody can tell me."
Secretary of Politburo of the Communist Party of the USSR: "I have ten trusted advisers. Apparently one of them is competent, but which? Even he doesn't know."
