Have you ever wondered what an army of toy ducks would sound like? Well, now thanks to this unexpectedly brilliant video, we know.
And it sounds like nothing we've ever heard.
A guy with the user name kevin237 writes that he was just "trying to embarrass my girlfriend" - instead, he's ended up with a viral video.
She was probably a bit embarassed too.
That sound will haunt our nightmares.
The video has been viewed more than one million times since being uploaded yesterday - it was also posted to Vine where it has a staggering 33 million loops.
Madness.
