From Winston S. Churchill (1874–1965), British politician, statesman, army officer, and writer, who was Prime Minister of the United Kingdom from 1940 to 1945 and again from 1951 to 1955, Blood, Sweat and Tears (2005):

A little mouse of thought appears in the room, and even the mightiest potentates are thrown into panic.
