In grade 8 Social Studies(History for most of you) we were told that whenever you hear Oh Canada, you must stand up. Just that afternoon in English class the band was down the hall playing Oh Canada for a teacher that had originally been American but just got her Canadian citizenship. Anyways, we had this really really dumb and just ignorant sub for this english class. We were in the middle of getting a lecture and I heard the anthem so I stood up and told everyone else to as well because hey, we're supposed to stand whenever we hear it. We stood for the whole song, not saying a thing, while the teacher screamed and screamed at us.
My favorite, and most patriotic school memory ever.
