"Sheena is a Parasite" was the debut single by the UK band The Horrors, released in April, 2006. It did not chart as it contained both stickers and inserts, therefore breaking chart rules.
The title and content were adapted from The Ramones single "Sheena Is a Punk Rocker" as well as The Cramps' "Sheena's in a Goth Gang", and chronicles the demise of punk music and its cultural influence. The music video was directed by Chris Cunningham. This ended a seven-year music video hiatus for the much respected Cunningham, who admitted to being "mildly obsessed" with the track, having come across it on MySpace. Following several Aphex Twin videos in Cunningham's filmography, the video was expected to be suitably twisted and quirky. The video starred Oscar nominee Samantha Morton as the song's manic, transmogrifying subject who whipped around like a banshee and spewed her intestines at the camera. Sharply edited and shot on a low budget, the video was instantly banned from MTV UK purely on the basis of the use of strobe lights, not because of the gory subject matter (as was erroneously reported by the [NME]). Cunningham did not want to edit out the strobing as he felt it would compromise his work. The video has aired on MTV2 in America.
