I had to watch this 3 times to realize they were singing this song differently. Kidding! This is a video of Mary Poppins singing ‘Supercalifragilisticexpialidocious’ re-edited with the smooth and dulcet tones of Death Metal. I would recommend watching this video in its entirety. I thought it was okay at first but by the second time Mary Poppins comes in I found it was pretty funny. Enjoy.
