the old greek root of that bring us oyster also brings us ostracize--

i heard the story--(and other can say whether its true or not) that voting greek cities was done by counting the number of voters, and then at election time, a man would toss a small sea shell into a baskets (they had problems counting the shards, not chads.) for yea /nae, dem/rep, whig/tory what ever..

when some one had offened public sensability-- a vote would be called and if lost-- the man could be banished... shells used for voting led to some one being ostracized..
