A group called the Key of Awesome updated the Bobby 'Boris' Pickett classic, "Monster Mash"...using horror characters from recent movies.

In the video, Frankenstein's monster sings as each character enters a party, but he's horrified when he sees the stuff that they do.

Hannibal Lecter eats his date, Leatherface hangs the butler from a meat hook and the little girl from "The Ring" crawls out of a TV and murders Frankenstein's monster by looking at him.
