A childhood belief about nationalities

when i was little my dad and i watched a show and there was a line on it where the main charectar kept shouting "The British are Coming, The British are Coming" like in the indapendance war, i didnt understand and asked him who the british were and why the were coming, and he said big men in red suits would come and get me if i didnt wash the dishes...i obediantly washed the dishes until i was 13.
