Ah yes ... memories this comment brings back of my summer job as a tab
operator in a local business.  

There was a programmer who liked to slip one of these 80x12 cards into
the decks he brought over to have duplicated.  He seemed to get his
jollies listening to the gang punch as it went 
	crunch
	crunch
	KWHAM		<floor shakes dramatically here
	crunch
	crunch
as it reproduced his deck.  Once he put a number of them into a deck,
one after the other.  The sound effects went something like
	crunch
	crunch 
	KWHAM		<floor shakes dramatically here
	KWHAM		<floor shakes dramatically here again
	KWHAM		<floor shakes dramatically here again
	plink
	<long silence>
Afterwards we found that some of the chad had jammed between two of the
punch dies and resulted in two of the dies snapping.  The gangpunch was
dead for about three days until all of the necessary parts could be
found and brought to the site.  Nobody ratted on the programmer, but he
never slipped another 80x12 card into one of his decks again!
