But instead of Instagramming a holiday which actually happened a year ago, the people who are caught on Catfish exploit their online anonymity to fool or mislead lovers.
Over time, the show has exposed many catfishers, each with a bizarre twist of his or her own.
There are women who have pretended to be more than one person, men who have struck friendships with other men pretending to be women, and people of both sexes who have used photoshopped photographs of others claiming that it is them.
The second episode of the two-episode return of Catfish is on a similarly outrageous story involving a shady man called Anthony and a woman called Larissa who has never heard his voice in the course of years of knowing each other.
The small town setting of Episode 2 in Yakima, Washington, has also gotten its fair share of Twitter reactions, in addition to the general disbelief over the gullibility of the victims.
According to the Empty Lighthouse Magazine, Larissa was catfished before by a female friend pretending to be a boy named Jose, and this time, she had sent $500 of her saved school money to Anthony.
