Famous quotes containing the words electric and/or toothbrush:
“Wisdom is like electricity. There is no permanently wise man, but men capable of wisdom, who, being put into certain company, or other favorable conditions, become wise for a short time, as glasses rubbed acquire electric power for a while.”
—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)
