Killing Best Friend Prank was an infamous prank video on Youtube by user Sam Pepper.
The video shows Cobly gets blindfolded and taken away into a car. It counties with Colby tied up to a chair and Sam blind folded, until he gets shot. While the video maybe fake that didn't stop the negative reception it got and it was later taken down by Youtube. Though there do exist reaction videos of the video, the video still hasn't been reuploaded to Youtube.
