I can write 5 different fake articles news stories about an accident or a crime doe by one of your friends. You can share this article on his/her facebook account and make him/her surprised by what the news say about hi/her. See this example:
Cairo, Egypt. Policemen from a night patrol were forced to stop and transport an aggressive man to the drunk tank. There would be nothing unusual about it if it wasn’t for the man intentionally getting in the police car after confusing it with a taxi.
