I've spent a lot of time watching Catfish this summer and have come to the conclusion that:
  1. They're an alien species and what started out as a disguise to blend in led to love
  2. It's actually God choosing who will bear his next child
  3. It's a robot coming to terms with real emotions but can only operate via the computer
  4. It's The Great Pumpkin finally trying to find Charlie Brown
  5. A muppet who has found they can move without human assistance and has always liked the cute intern
  6. It's a rogue marbel that escaped from hungry hungry hippos and is finally facing the real world but it's easier to disguise himself as a human online
    Rogue marbel idea is taken from SNL thanks to comedy genius Andy Samberg as Nic Cage
