Bishop: “I’m afraid you’ve got a bad egg, Mr Jones”; Curate: “Oh, no, my Lord, I assure you that parts of it are excellent!” “True Humility” by George du Maurier, originally published in Punch, 9 November 1895.
TIL: A "curate's egg" describes something that is mostly or partly bad, but partly good. https://en.wikipedia.org/wiki/Curate's_egg ‎- Черчилль
