Have you ever encountered a bad egg?
I was shocked when I learned the reason why many chefs crack eggs in a separate bowl is to make sure that the egg is fresh. What are the chances to stumble upon a bad egg? What does a bad egg even look like? I heard it smells awful. But I have never had a bad egg.
On the other hand, “bad egg” is also a colloquial phrase, perhaps an old colloquial phrase that would make you sound unfashionable if you used it nowadays: a person or a scheme that doesn’t live up to the expectations. Clearly, it came about when a person cracked open an egg, only to find that it had gone bad. But why egg? Why not a watermelon or a pistachio? When was the first usage of the phrase? I went digging for answers.
