Me and my room-mate have been discussing these videos for long hours. She's more of a paranormal person than I am but we both agree to the point that this seems to be the most realistic and best achieved ghost hoax of all time.
Part one of the thing is all about a ghost girl that appears behind a pantry door and opens it. The owner of the house first decides to leave the camcorder on during the night and I think later he stays there, awake and even invites over a skeptic:

(notice that there isn't any space between the shelves and the door for a person to hide in)
Part two is all about sightings of the ghost in other rooms. As you can see, it's easier to debunk but hey, together with the previous recordings, I don't know what to say:

Feel free to debunk it... ans add other pseudo-ghost videos
