Not a shitpost. I remember this happening quite vividly. We sat in an auditorium and watched some giant video about the dangers of drinking and driving. They talked about texting and driving because cell phones amongst teens were starting to become a thing but no video was made yet. After watching it they talked about an exercise that we would do and asked for participants. I put my hand up out of boredom but wasn't chosen. We went outside where there was at least one firetruck, an ambulance and a couple of cop cars. A police line was set up and beyond it were the people who had been picked that were either lying on the floor motionless or acting injured. Some more camp than others. They then took some more participants and had them be 'first responders' to help the injured until professional help could come. After we finished we went back in the auditorium and talked about what happened. I know there was a gong involved somewhere because someone hit it and half of the class laughed almost immediately and the teachers snapped to say it was more serious and solemn. Can't really remember anything after that but my guess is that from there on it was just generic field trip shit with us shuttling back to our main school.
