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 a user AmbitiousMusicNote.

The video is disguised as a tutorial on how to tell if the video has a screamer, However, there is a screamer at the end. After the title is displayed, the video shows text that says "You'll never pee in your underwear again". The first step is that you don't have to look closely at the screen when the video prompts you.

The second step is not to turn up the volume when it does. The third is that when things are suspiciously calm there is chance that there is a screamer. Immediately after the text "Rat" appears, a demon child from the film Dead Birds appears with the same scream from What's Wrong? repeated three times. The video ends with the "tip": "Don't ever fall for this again".
