GO TO 4:50 TO GET TO THE ACTUAL PRANK Note: When we did this, we never thought it would get as many views as it did, so this was at first posted just to show my other friends. And yes, I realize how poorly I edited this, but like i said, this was first made just to show my friends. so me and my friends were up late at night, and we started talking about marble hornets and Slender man. So we decided to do a prank on my sister Who also knows about Slender man. We went through alot as you can see to pull this prank off…This was filmed at my birthday party the day before my real birthday (June 27). UPDATE: Since I posted this video on YouTube a few months ago, some strange and unusual things have been happening to me. I don’t know what’s going on. I am currently documenting the unusual occurrences going on around me and I have started to post them on YouTube. Here’s the first clip I posted: www.youtube.com
