An example:Pope John XXIII
One of the few pontiffs in history with a rich sense of humor, Pope John XXIII once reported to an interviewer that important problems would frequently come to mind in the middle of the night, disturbing his sleep. Half awake, he'd make a mental note: "I must speak to the pope about that." "Then," he confessed, "I would be wide awake and remember—I am the pope!" Once asked by a journalist, "How many people work in the Vatican?" the pontiff pondered the question, giving the impression that he was trying to come up with an accurate estimate.
Then, with a straight face, he answered: About half.
