Humpty Dumpty sat on a wall.
Humpty Dumpty had a great fall.
All the king's horses and all the king's men
Couldn't put Humpty together again.
It’s an old nursery rhyme that was originally posed as a riddle, and the answer was that Humpty Dumpty was an egg.
If it has any meaning beyond that, it’s yours to make. I personally like it being a story of a king that spent all his time and efforts on building an army while ignoring everything else, just to have some other unforeseen thing topple his rule in a way that no army could repair.
