I was reminded this by watching a CPG Grey video.
Its typical for Americans to say the word "Mississippi" between digits to approximate counting by seconds. Since I grew up in Mississippi, I just always assumed that only people who lived in Mississippi said "Mississippi" while counting seconds and that people in other states used whichever state they were in order to do the same (i.e., "One Alabama, two Alabama; One Massachusetts, two Massachusetts).
That might be a fun system - "One Chad, two Chad, three Chad", etc.
