The month of November, with the “N” changed to “M”, now is synonomous with MEN (who are proud to be able to grow a mustache because women can’t, or if they can they don’t want to) doing something to improve men’s health (e.g., preventing or treating prostate cancer), so they won’t die so young in the future. So now when you see giant mustaches sprout on the front of cars you know what it means. Of course the really ornate facial foilage that adorns a few mustache afficionados, and of course mostly earns the owner a lot of ridicule, takes a lot more than a month to grow. Have a look at the Movember website or Wikipedia.
