You can't walk for more than five minutes in the UK without tripping over some nonsense like this. History is very important, and traditon has its place, but really? As a brit I find it all kind of tediously performative sometimes.

It is truly strange how my country can create a political and cultural operating system that allows this stuff to just go on and on for almost 800 years, right up to now.
I mean, you have to admire the stamina for that.
b) In case you are one of today's Lucky Ten Thousand, this is a reference to the real-life Ceremony Of The Keys[1]

And yeah, I knew about the Ceremony of the Keys, but not the details. Didn't know it really has that kind of scripted dialogue that Pratchett parodied there.
