I found this interesting quote on NPR's site. JS Bach was quite the guy with a simile.
J.S. Bach's Coffee Cantata (BWV 211) is, by its very nature, a departure for the oft-solemn composer, who frequently wrote in coffee shops. One segment of the piece translates as, "If three times a day I can't drink my little cup of coffee, then I would become so upset that I would be like a dried-up piece of roast goat."
