An already tense relationship between the world's two most powerful Argentines became more so recently when the pope rejected a sizable charitable donation to an organization he backs from Argentina's president, Mauricio Macri. The reason? In addition to possible concerns over the donation's political overtones, a communication from the pope to the office of the nonprofit, according to the Vatican Insider, had a postscript: "I don't like the 666."

The proposed amount of the donation was 16,666,000 Argentine pesos, or about $1.2 million to Scholas Occurentes. The strange specificity of the sum, which contains the number many superstitiously believe can invoke the Antichrist, left some wondering whether the donation was really a troll of presidential proportions.
