Some people do some really stupid things when they’re bored. This is a good example.

Some bored high school students from Sydney, Australia thought it was funny for a boy to throw seats from the train they were on into the pathway of motorists traveling down one of the city’s busiest motorways. It was beyond dangerous and beyond senseless, but the boy’s friends didn’t seem to think so. They filmed the boy’s activity on video and uploaded it on Facebook. In the video, one of the teens can be heard saying, “You hit a f*cking car, bro, that’s gonna be on the news!”

After the boy’s mom saw the video, she promptly took him to the police, where he and his friends faced five years in prison.
