Two Russians walking in St Peters Square. "It's snowing, said the wife." "No, it's raining," replied her husband. They continued arguing, until the husband suggests: "let us ask comrade police officer, Rudolph, the police always know." They asked him and he told them, "It is definitely raining, comrades." The couple walked on. "You see," said the husband......"Rudolph the Red knows rain, dear."
