This guy wanted to see how his girlfriend would react to "The Ring" girl. He did it by creating a ghost like puppet that would clamp to the tv screen.

He had to stop her running out the house. She said "Her legs were like jelly, At the end you see her looking over at it. She was asking. "What is it? What is it?"...she seriously sounded like a squealing pig.

the boyfriend spent quite a few weeks planning the prank.
