Did he just say that?

So I went to my chiropractor because my back was really hurting and my hand was numb.  After I was all popped and loosey goosey feeling, he started saying how nice it must be to finally have a girl.  He mentioned his wife's cousin was expecting their 4th and they had all boys and were waiting to find out on the last.  But they were hoping for a girl.  Yeah, I said, I really loved having my little girl.  I then mentioned my friends who had 4 girls and then they had a little boy (cutest little guy).  To that he responded "Oh, five.  You know I find that everyone who has five is either catholic or farmers."  Ah, okay.  The only thing that came from my mouth was "Oh  my."  I really did not know what else to say.  Does this mean my friends in MI are secretly farmers?  I did see pictures of them with dirt in their front yard.  Hummmmm.......Or are they secretly Catholic!  And does this mean we will have a 5th!
