When you're young and have siblings, it seems there's little point to their existence except to torture you. This video proves that belief to be true. Originally posted to Reddit and retweeted across the net because it's hilarious, the video shows a brother playing a prank on his sister.
The crux of this video is that, as the brother flickers the power on and off, tiny screams can be heard. Hehe, pure evil.
If my brother did that to me as a child, I'd still be recounting the incident with horror.
People are a little obsessed with this prank.
If you've played a prank on friends or siblings that you think rivals this one, please share.
