I was in English class with a bunch of friends and someone bet me that I couldn't make a shot with a paper ball into the trash can from across the room. The trash can was also small, and under a desk. Needless to say, I made the shot. After that, I screamed "Yeah! Fuck you guys!," and a teacher came into the room and yelled at us for being loud, while a kid from my class stood behind her and mocked her, causing us to all laugh while she was yelling. Eventually, she just got mad and left the room.
That was a really good day.
