I saw the guy from a new show called "Catfish" on Leno last night, all about people who go online pretending to be someone else. The guy who makes the show actually had an online relationship with a woman who was pretending to be 14 different people. This guy is a professional photographer, and he was contacted by a "young woman" who was painting some of his work. He then started a friendship with her, then began an online romantic relationship with her "older sister". He also chatted online with her parents, friends and other family members. Turned out, it was one woman pretending to be all of them. He started with his own, but also does episodes about other people being taken in by their online relationships.
