Oh god, I used to work IT for a company that had a European office so users getting documents set to A4 was not unusual. The problem came when they tried to print one of those documents and the office printer would sit and complain that it didn't have any A4 available and wouldn't print anything in the queue until that was fixed. And of course users had no idea there was any difference between letter size and A4.
Due to the way the Electoral College works (even when not being undermined by bad-faith actors) it is possible for a candidate to win the popular vote (i.e., get more raw votes than his opponent) and yet end up with fewer Electoral College votes thereby losing the election. This has happened many times, and I believe no recent Republican president has won the popular vote with the exception of Bush Jr.'s second run.
It's one of these but for planes.
