YouTube videos are fun to watch, but some leave you with a literal chill down your spine.
Like maybe you've seen the Max Headroom broadcast interruption that happened on PBS in '87.
Perhaps this creepy commercial from the 1960s is where your fear of clowns stems from.
Or maybe "11B-X-1371," the video featuring this person in a plague doctor costume, kept you awake for days.
The internet can be a weird place, so tell us: What's the creepiest YouTube video you've ever seen?
