My older sibling and I spanned the boundary between lookup tables and calculators. Her math exams came with booklets of sin and cos and log tables. Mine didnt because I was expected to use a calculator. I think the tables all evaporated in under two years around 1984 (or maybe thats just as far back as I can recall)

Once the Great Flood was over, Noah let all the animals off the Ark, and told them to go forth and procreate. And so they did, except the snake couple. So Noah made some wooden furniture for them, and thus the snakes were able to procreate.

You know, because the snakes were adders. They needed log tables to multiply.
