In like 11th or 12th grade, we were shown some cautionary video about drunk driving and how you should wear your seatbelt, but between the narrator's commentary, the video had tons of extremely dramatic and over-the-top (obviously fake) shots of people flying out of their windshields and smashing into walls and poles and shit, and my friends and I were losing our fucking shit the whole. THEN we all had to do a little quiz with a short answer section afterward, and we were VERY audibly trying to hold back our laughter. The rest of the class wasn't as immature as us idiots, but listening to us trying to keep ourselves from bursting out laughing in an otherwise silent room made THEM start laughing.
