The insanity of the British

I've recently come up with a theory.

It is that the British are, as a nation, insane. 

It starts in the 19th century, when the British were so repressed that sexuality and emotion were things that were whispered in the dark. At the start of the 20th century, sea side acts were release valves for the mounting wave. 

But then the two world wars happened, and something in the British psyche snapped. Part of kept on being repressed, the other part went insane. We had spike Milligan and the goons, then monty python, moving onto things like the Young Ones, then the more modern Mighty Boosh. All examples of British comedic eccentricity that hasn't left us since.
