Everything I know about Chamberlain and Hitler, I learned from Robyn Hitchcock:

Chamberlain
Came crawling from Munich
With one piece of paper
He waved at the camera
'Peace in our time'
Oh thank you Herr Hitler
Tell that to the Polish
Tell that to the Jews

-- Cynthia Mask, verse 2

It's not much, but it's more than this guy knows, and he gets to be on TV! (drink every time he says "appeasement" !)

On the other hand, Robyn's presentation of history might not be entirely accurate:

Napoleon
Wore a black hat
Ate lots of chicken
And conquered half Europe
Napoleon
Was caught by the British
Imprisoned on Elba
He died on the phone

-- Cynthia Mask, verse 1

I suppose the lesson here is: always verify, especially if your source is a GOP shill.
