one time in high school someone's phone went off in class and the teacher wouldn't let us go to lunch until someone owned up, so a kid googled the geneva conventions and told her collective punishment was against international law and we all got to go to lunch
My ex used to stick her fingers in my mouth whenever I yawned and it irritated me a lot. I've just found out that she and her husband are divorcing and I'm glad, I can guarantee the ruined yawn thing is largely the reason. You shouldn't fuck about with a good yawn.
