Sent by a priest friend…
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!”
Thus, the origin of the phrase “The Curate’s Egg“, describing something mostly or partly bad, but also partly good.
This is from Punch of 9 November 1895 by George du Maurier.
