Remember this person? He attended my wedding (#1)

Here's a caricature I drew of a friend in Boot Camp (1971).  He also attended my wedding that same year.  From Brooklyn; a math major (NYU); very funny man.  Our Company Commander liked to use the expression "zilch point shit" as a way of letting us know the odds of something good happening to us that particular day, e.g. "smoke break?" chances are exactly "zilch point shit", etc.  As a mathematician this expression opened up an entirely new and somewhat bizarre field of mathematical study.
