By the time I realized that the '80s were actually the decade of greed, it was too late--I had declared my college major to be classical Greek.  This may not have helped me get a gig on Wall Street, but it still pays dividends today.  For example, it means that the Orthodox phos-zoe cross pictured below is not, um, Greek to me.
