I still remember an event years ago at Melbourne University. Workers were working on the tram tracks outside of the university. A group fo students went to them to warn them that another group of students were going to dress up like police officers and ask them to remove themselves from their worksite and not to worry about them. They then called the police and told them that a group of students were causing traffic problems by pretending to work on the tram tracks. They then went and got some popcorn and a good seat.
