This is a video of the Spongebob Squarepants theme song slowed down 800%. It sounds like some sort of demonic chant. I've actually heard sounds like this coming from my closet at night, and those are the nights I go sleep on the couch with the TV on. At least until that girl from The Ring tries crawling out of it, then I kick her in the head until she retreats back into the Home Shopping Network. Honestly, I haven't been sleeping that well lately.
Keep going for the audio. It's freaky.
Thanks to Silvermidnight, who's already slowing down the Teenage Mutant Ninja Turtles theme for more nightmare fuel.
