I recently found a "spud wrench" on Ebay. ( A spud wrench is an open end or box end wrench with a long tapered handle.) The handle is used to line up the holes in two sections of structural steel, so that a bolt can be inserted and tightened. In the description the seller said the wrench would still "Make those zeros rhyme". I emailed him and he said this was a saying endemic to iron workers, or connecters, and that he had heard it all his life. He didn't know where it came from, but it meant lining up the holes.
