Creepy... BOO!!!
I can see you are all a bit tense roght now, so I thought it's time for a small joke.
An american is looking to buy a castle in Britain. He makes a few calls and sets up a tour of the place with it's current owner. After browsing about the castle, which looked really good, the american asks the owner: "The castle is excellent, the rooms perfect and the land is beautifull... But... I've heard stories of a ghost who wanders the castle. is there such a thing?"
Shocked, the owned answers: "Ghosts!? No, sir. I haven't seen a ghost around here for the last five hundred and seventeen years.
