For those trying to get back at their ex, buy Cathy: the Imaginary Girlfriend for only five dollars and she will be your girlfriend on Facebook for ten whole days.
Upon request, Cathy is also willing to post three messages to your wall. Her advertisement states that she is a 23-year-old student who currently lives and studies in New York City. For only five dollars it's a pretty decent bargain. It's hard to tell whether or not the advertisment is real, but perhaps this is a new form of income for students. Either way, if you want Cathy: the Imaginary Girlfriend to be yours for ten days, check out her ad and see for yourself.
