It was their anniversary. Guy decides to set up a camera and film his girlfriend's reaction when telling her he cheated on her.  The on HIM!

The prank may have gone more smoothly had the girlfriend not seen her boyfriend setting up the camera.  She thought he was going to ask her to marry him, and when he didn't, she got him GOOD!

Prankster Roman Atwood thought he was going to pull one on his girlfriend, but the table turned.  It was so bad, he almost didn't share it with the world, glad he changed his mind.
