"Perfect Insanity" is a song by American heavy metal band Disturbed, released as a single from their fourth album Indestructible.

Coming at you from the perspective from the individual who is [insane] and warning people around him, particularly his love interests, about his psychotic tendencies.

The video depicts vocalist David Draiman, locked inside of a room, in a straitjacket.

As he tries to break free, the video shows the band playing variously on a stage, in between clips of Draiman trying to escape from the straitjacket.

As the song finishes, the video switches to a scene of a graveyard, implying Draiman had died insane.
