We used unused punchcards to make flashcards in elementary school in the late 80’s / early 90’s. I guess the county bought a bunch and had to find another use.
And now I realize the primary definition of flashcard has changed since then, from study aid to digital storage.
Rom inspired his son to enter into a very successful career, just probably not in the way he would have liked. Then Nog inspired Rom to change career tracks and become a station engineer, so I guess it all worked out.
