@RickiTarr when I was in Primary School, maybe 3rd or 4th class, one of the teachers gave a speech to the whole school during assembly about the importance of manners. I was not a disruptive kid, and in no way planned it, but at the precise moment the teacher finished their talk, I did the loudest burp I had ever done. It's possible I've only ever managed to match it during the intervening decades. That led to my first ever (and one of maybe only 2 or 3 in my entire school years) detention.
