Famous quotes containing the words electric and/or toothbrush:
“That’s the down-town frieze,
Principally the church steeple,
A black line beside a white line;
And the stack of the electric plant,
A black line drawn on flat air.”
—Wallace Stevens (1879–1955)
“Loss of freedom seldom happens overnight. Oppression doesn’t stand on the doorstep with toothbrush moustache and swastika armband—it creeps up insidiously ... step by step, and all of a sudden the unfortunate citizen realises that it is gone.”
—Baron Lane (b. 1918)
