@dd8b9125 @19bcf1ed I slipped a marginalium into one of my intro physics lab manuals glossing "coax cable" as deriving from Greek κοαχ=frog because it makes a frog croak when you rub it together (which it really does, at least for the cables that we had). I waited years for a student to trigger a collective groan, but no such student came my way.
