My little book of essential militaria contains numerous similar quotes, but the one I like best is this:
"I thought he was talking about our mess bill": made by an anonymous RAF pilot upon hearing Churchill's speech containing the lines 'Never in the field of human conflict has so much been owed by so many to so few'.
Not sure if it is the original source, but I believe that line was uttered by one of the characters (Hurricane pilots during the BoB) in Derek Robinson's outstanding novel
Piece of Cake.
