An old Jewish man was on the subway and he sat down next
  to a younger man.  He noticed that the young man had a strange kind
  of shirt collar.  Having never seen a priest before, he asked the man,
  "Excuse me sir, but why do you have your shirt collar on backwards?"
      The priest became a bit flustered but politely answered,
  "I wear this collar because I am a Father."
      The Jewish man thought a second and responded,
  "Sir I am also a Father but I wear my collar front-ways.
  Why do you wear your collar so differently?"
  The priest thought for a minute and said
  "Sir, I am the Father for many."
      The Jewish man quickly answered,
  "I am the Father of many, too. I have four sons, four daughters and more
  grandchildren than I can count.  Still, I wear my collar just like everybody else.
  Why do you wear it your way?"
      The priest who was beginning to get exasperated thought and then blurted out,
  "Sir, I am the Father to hundreds of people."
      The Jewish man was taken aback and was silent for a long time.
  As he got up to leave the subway train, he leaned over to the priest and said,
 "Mister, maybe you should wear your pants backwards."
