Why did an egg choose to sit on a wall? Surely eggs should sit in egg cups or in egg trays or nests where they have adequate measures to prevent them from rolling. Humpty's decision is ridiculous and caused an unnecessary waste of taxpayer funds. His decision was almost as dumb as the decision to use all the king's horses and all the king' men to try and reconstruct Humpty.
As a kid this nursery rhyme seemed utterly stupid but now I realise it makes perfect sense. I think it was a comment of the propensity of people to do all sorts of stupid irrational things and the propensity of government to do even dumber things.
Our government is basically a bunch of big Clydesdales with superglue, eggshells and bits of yolk stuck to their hooves. If we used all the horses and men more smartly we might get somewhere.
