Spooky Scary Skeletons

Spooky Scary Skeletons is a screamer video uploaded to YouTube by the user Canadian FBI on July 24, 2012.

The video starts off showing various pictures and animations of skeletons set to the song "Spooky Scary Skeletons" by Andrew Gold. However, after at 15 seconds mark in, a rapidly flashing picture of Jeff the Killer at a negative rate pops up, accompanied by a loud scream. Eventually, the video gets back on its original tracks and the picture of Jeff the Killer changes to similar images and GIFs of the skeletons from the beginning, but edited to appear oversaturated and distorted, with excessive contrast. Through all this, the scream never ends, playing in a loop until the very end of the video.

There's a safe version without a screamer for that, which is original.
