The Elmo Song
From Screamer Wiki
The Elmo Song is a screamer publicated on YouTube in September 2007 by the user YvSvAllo. It begins showing a website link, but then it fades out and a photo of Elmo from Sesame Street with a line of text saying "Let's pay attention to Elmo's Song!" along with the music Elmo's song, although the music is very low. After about 10 seconds, a close-up picture of a blurry face pops up along with a very loud scream.
