C'mon... we've all farted in public around people. I'll start. English AP exam in my junior year of high school. Whole damn year has been leading up to this moment everyone is fucking freaked out because it's our first. I'm not freaked out. Everyone else studied during lunch. I ate. "Open your exams..." Lots of papers rustling, tearing, people adjusting. My stomach starts making noises and as soon as everyone sits down I have a long, high pitched wail followed by a horn honk. Tried not to react at all and probably really failed at that.
