"Cursed" YouTube Video
This video shows a lowpoly 3D Scooby Doo animation found in SpongeBob SquarePants: Battle For Bikini Bottom, an XBox video game, where it served as an advertisement for the game Scooby Doo Night of 100 Frights. People who play the video report that the sound is badly messed up, giving it an unsettling, disorienting vibe. The timeline bar claims it is 3:48 long, but the bar fills and ends in 1:07. The video then displays a loading spinner for another minute, then ... depending on the configution of your box ... the rest of the music will begin to play. The rest of the video footage is, presumably, forbidden.
While one might assume it is obviously just a corrupted video/audio stream whose metadata the YouTube player is misinterpreting, it says right in the comments that it is cursed. I'd assume that it's a very bad idea to FFprobe if you like living in this dimension.
Scooby Scooby do, zalgo you.
