Pilot fish reads a true tale of IT life about clearing jammed keypunches with a makeshift hacksaw, and it brings to mind something that happened years ago.

Tech tells fish that he’s careful about who he gives these too. Some users had managed to cut off the punch hammers rather than gingerly removing the jammed cards.
