In October 1999, John Katsilometes reported that Cipriano had crank phoned "just about every emergency [live] report worthy of national coverage," such as those regarding the Columbine High School shootings and the car crash death of Princess Diana. Television stations Cipriano has successfully prank-called range from national and local news networks like NBC News, Fox News, C-SPAN, ESPN to home-shopping channels and religious networks. In 2014, Cipriano suggested he has made around 10,000 fake phone calls.
