Sniper Prank on Japanese TV

Only in Japan. Those guys sure can be extreme. This is what the video is all about, they got a guy in a room and they scared him into thinking that a sniper was shooting and killing everyone in his room. They were able to get the effects well organized that there were breaking windows, gunfire, and stuff. While the video is funny enough to share, I wonder how scary it must be for the prank victim. LOL.
