The video was filmed in Toronto, Canada on April 1–2, 2007. The video, which was directed by Lisa Mann, premiered on Monday, April 23, 2007 on MTV2 in the U.S. as part of their Unleashed program. The video is not available on MTV2.com by UK residents. UK TV channel Scuzz is now showing an edited version of the video; it only has a brief moment at the start through the key hole and then cuts out the sequence with Bert being stabbed in the wrist and then it healing itself. The part where Bert coughs up blood after drowning in the couch has also been cut. It also cuts out the part where Jeph offers Bert a lamb's head on a plate.^[4]

The song was used in CBS' Moonlight for their fifth episode, and an orchestral cover was used in the trailer for the 2010 remake of Clash of the Titans.^[5] It was also played during Francesca Jones's rhythmic gymnastics routine at the 2012 London Olympics.
