A [[Nine Inch Nails music videos|music video ]] was released in 1990, using the "Short" remix of the song. It was directed by Brett Turnbull. The video contains two women dancing with each other at the beginning before cutting to the main focus of the video. A woman, nude except for what looks like straps to spelunking gear and a halogen lamp, walking a shirtless, wrist-bound Reznor with a bag over his head through what looks like an industrial warehouse complex. He is then strapped into a large rotary harness where she spins him throughout the remainder of the video. These scenes are intercut with two young gay lovers, a man and woman wearing ritualistic dressings and dancing, as well as visuals of pierced genitalia (both male and female), all reflecting the song's dark, sexual aspects.
The video was banned from MTV and most major outlets. A partial version of the video can be found on ''Closure.'' There were reports that the complete video was shown at dance clubs in the early 1990s and can now be found on the internet.
