A real reason to follow the stock market: booze

Just launched at each of these upscale barstaurants: a drink whose price goes up and down each day, mirroring the whims of the stock market (Luau = rum-charged punch, Il Sole's = Prosecco cocktail). Prices're down almost 40% from their original $14 -- baselined back to the market's price in February 2008, when people gladly paid $14 for drinks, and buying that duplex was the best idea you ever had.
