Because this is the internet, here's a video of Mary Poppins and Bert appearing to sing a death metal version of Supercalifragilisticexpialidocious, as created by Andy Rehfeldt (who played, arranged, and recorded all the instruments). I'm not gonna lie -- I banged my head so hard now my face is bleeding. "It looks like you broke your nose." I know, I'm so hardcore I've actually been banned from all mosh pits worldwide. Which is exactly why I'm trying to open a music venue in space so we can have a zero gravity shit-show. NOW KICK ME INTO THE SUN.
Keep going for the video.
Thanks to BRD, who was really hoping for a death metal version of A Spoonful of Sugar.
