I've been reading a lot about Thomas Edison

Step right up, step up! Hear the incredible speaking machine, the wonder of an age filled with wonders! Marvel at the voice of the Wizard of Menlo Park himself, the father of electricity, master miracle-maker of this great American age, the man who has yoked the very forces of sound and light themselves to the gleaming plowshare of progress! Listen, but carefully: for contained within the ordinary vessel before your very eyes is not simply sound, not merely voice, gentlemen and ladies, but something subtler -- a force that has confounded the minds of mankind since the patriarchs themselves strode the land of Abraham. Indeed, friends, within you will find humor -- and our own Mister Edison, proving himself master not only of the elements of the earth and the machines of mankind's hand but also the jolliest fruits of its spirit, draws deep from that mysterious well which the Creator in His infinite and inscrutable wisdom saw fit to bestow upon the sons and daughters of the human race.
