This may be off topic, but a few years ago, my sister got into a little bit of a war that I instigated. I changed her Netflix display picture into a monkey, and she retaliated by changing mine to another animal. This went on and on for a week and I was winning teasing her.

Then I immediately had to give up. She had done the prank equivalent of a war crime and had changed my language settings to Yiddish. I messaged her that I surrender and had to suffer some hard work to change the settings back.
