Hey Arnold Subliminal Message Laughing Grandpa

Hey Arnold Subliminal Message Laughing Grandpa is a screamer video by user likekurdtcobain.

The video shows a still image of Arnold's grandfather from Hey Arnold!, with a sound clip of his trademark laugh. Over the course of the video, his laughter is gradually slowed, so that the viewer can identify a hidden message. However, after 36 seconds, the face of a young man with down syndrome appears with an ear-piercing scream. The scream in this video would later be used for G-Major Videos.

There was a variation of it exists where the face is replaced with a picture of Regan MacNeil with the same scream from The Maze.
