The demented mashup artist known as There I Ruined It (previously at Neatorama) combined "Psychosocial" by Slipknot with "Baby Shark" in order to introduce our young children to heavy metal. At reddit, he said he made this to terrify his son for Halloween, but expects that like his other metal mashups, it may become the child's favorite song. From the YouTube page (which has since been pulled):
Sorry the comments are disabled. YouTube is rightfully confused as to whether or not this is a children's video.
I can tell you, this is not a children's video, but you might get a kick out of it. -via reddit
