Many years ago, when I was working as an engineer at WBAA, Purdue
University, the local telephone company put in a new switch with
newfangled line frames with a polarity reverse in the frame.  The
installers, who had been reversing the "outside" side of the frame for
years so the "inside" would be correct, reversed the "outside" when
they wired up the newflangled frames.  Since there was a reverse in the
new frame, the "inside" side was now reversed.

Anyway, this ended up reversing the polarity of our program circuit
between the studio and transmitter.  About a week later, the morning
announcer asked what had changed.  He said that his off-the-air
headphone monitor was somehow different.  We reversed the wires at the
studio and all was back to normal, until the phone company got around
(in a couple months) to fixing their reversal.  This time the morning
guy knew what the problem was and reported it right away.

This is not to mention the problems that were caused when the
transmitter fire and burgler alarm line polarities were reversed, but
that's another story!
