How to tell if a video is a screamer

How to tell if a video is a screamer is a prank video published to YouTube in 2011 by the user AmbitiousMusicNote.

Video
After the title appears, the video shows text that says "You'll never pee in your underwear again". The first step says to not look closely at the screen if the video tells you to. The second one is to not turn up the volume if it says so. The third is if things are suspiciously quiet, there may be a screamer. However, right after the text "One tip" appears after, a demon child from the film Dead Birds appears with the same scream from What's Wrong? looped three times. The video ends with the "tip": "Don't ever fall for this again".
