The star salesman had included an item "$50 for girls" on his expense
  account.  The boss called him into his office and said "Look, I don't
  mind you enjoying yourself on these trips, especially when you're such
  a good producer.  But let's be a little more tactful.  List those kinds
  of expenses as being for hunting."
    The salesman's expense accounts thereafter included "$50 for hunting"
  on a regular basis.  That is until one month, a new entry read "$250
  for cleaning rifle."
