Wonder What Our Parents Did In Office

Every day I come to work and find that there is very little work. Fortunately we live in the times of the internet and therefore one can always kill time searching for music, emailing, chatting, playing games or just tooling around on google.
But that's now. Of late I have been wondering what people before us must have done to kill time in office, considering that even back then they could not have been busy all the while. Did they play with their out-trays and in-trays? Did they take an inordinately long time crafting letters in the Queens English just to kill time? Did they keep re-tying with their shoe-laces?
None of the above somehow seem like things they might have done. You might say that they chatted a lot to kill time, but that I think is unlikely given the stiff upper-lip atmospheres in offices of yore.
I sometimes wonder if I would find work bearable if they took away my computer or disabled the net. It would be quite like they pulled the plug on me. If any of you think you know how guys killed time before the PC or want to speculate please do so.

Maybe they made paper fans and fanned themselves given that AC workplaces were fewer :-)
