Famous quotes containing the words electric and/or toothbrush:

    The sight of a planet through a telescope is worth all the course on astronomy; the shock of the electric spark in the elbow, outvalues all the theories; the taste of the nitrous oxide, the firing of an artificial volcano, are better than volumes of chemistry.
    Ralph Waldo Emerson (1803–1882)

    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)
