Which three?

My theory is that universal public education was less than a generation ago in most places, printing books was still expensive, and forget movie cameras and audio recording devices. You really had to be sure of the stuff you wanted to record before you recorded it in those days, in any medium, and you needed some money to be able to do it. As a result, a lot of the content we see nowadays that documents how average people talked and behaved was never written down or filmed or whatever.

So people probably didn’t really say “what in the Sam Hill…???” they probably said “what the fuck!” You just don’t know it because every ten year old didn’t have a 4k video camera in their pocket ready to roll on every bullshit that everyone did.
