When you find yourself trying to remember a show (or any works) that's on the tip of your tongue but just out of reach, come here - the collective brain of the TVTropes community can probably help. Post all the details you can remember (examples help). If you're looking for a trope, head over to Trope Finder. Have general questions about tropes? Visit Ask The Tropers!
That's not the one.
It's something along the lines of "The tailor hates no one more than the other tailors in town, and the painter the other painters, and the stonemason the other stonemasons." But I probably have all the example professions wrong, because I can't find it with Google or Bartlett's Quotations using the words I remember (and I've tried a lot of keyword combinations).

I'm looking for an old quote, possibly from the Bible. I can't remember enough of the exact wording to find anything with Google or Bartlett's Quotations, but it's about how people of a profession hate all the other members of that profession.
