: Where does "good egg" come from?
Well, literally a good egg is one that is fit to eat, as opposed to a bad egg which is one that has gone rotten. Now that most of us in the English-speaking world buy eggs that have gone though rigorous quality controls, it is quite rare to crack an egg and find it gluey and smelling of sulphur, but this used to be a common experience. (I have a cookery book written only 50 years ago which advises always breaking eggs into separate cups, so that a bad one won't spoil the rest. Nobody now expects to find a bad egg in a newly-bought box, but only half a century ago you had to assume that you might.) You can't tell from the outside of an egg if it is bad - you have to crack it to find out. So it was a natural metaphor, when a person who had at first sight seemed OK turned out to be a wrong 'un, to call him or her a "bad egg", while someone who proved to be honest and helpful was a "good egg".
