So I found the video in which the K-pop hypnosis happens. It might just be a compilation though, as there's only like 3 seconds of it. I'm gonna ask on the group's subreddit if they can find any more.
Not 100% sure, but I think you all will get a kick out of this. Parts of the both the song and the video are hypno themed. The Lonely Island - Go Kindergarden (Feat. Robyn) - [3:00]
