Nine Inch Nails' 1994 music video for 'Closer' has remained one of the most discussed and controversial clips MTV ever decided to air, but before that milestone, the band pushed the limits with 'Happiness in Slavery.'

The video for the 1992 track features a man being both tortured and pleasured by a machine resembling a demented dentist's chair, with the man's blood being used as fertilizer for a garden beneath him. Due to shots of nudity and violence leading to the man's death, the video was almost universally banned by TV networks.
