Those fellows with the powdered wigs and the pianofortes back in the day in Vienna tried to make the greatest sounds ever made by humans, but fell a bit short. The dinner bell comes to mind. That’s a really, really good sound, of course. The dulcet tones of the words “Open Bar” come to mind as pretty sweet, of course. “Hey, baby, I just got back from shopping at Victoria’s Secret” has fired many a endorphin receptor, naturally, but it’s not the best thing, ever.
The greatest sound ever produced by man is the sound of a Model T starting.
