It is said that he replied to Cardinal ***, a not very regular prelate (some say Abbot Terray), who was complaining of suffering like a damned person: "What! Already, monseigneur?" In my opinion, he might well have said this about one of his patients, but not to his face; manners would not allow that.
Notes from Wikiquote
An "regular prelate" (prélat régulier) is a high-ranking churchman; this is a play on words, implying that he was irregular, that is, immoral. Abbot Terray is Joseph Marie Terray.
