This threatened to destroy us all.
A throwaway joke, it caught on stunningly, peaking around the mid-AP50s when every writer and every reader capitalised words for effect (usually involving corporations or a Satan joke).
Its sinister influence can be seen as early as AP52, when it was sufficiently widespread for me to write Timekeepers without any capitalisation and consider it a concept review.
Another joke, then, that was driven into the ground.
Oh no! Our wives are going to kill us!
