"Thoughtless" is a song written by American nu metal band Korn for their fifth studio album, Untouchables. "Thoughtless" was released as the album's second single sometime in July 2002. It is about Jonathan Davis' being assaulted and harassed in school and dreaming of seeking revenge on those who bully him. A music video was produced for this single, directed by the Hughes Brothers, known for their work with Korn's previous video, "Here to Stay". The plot of this video revolves around a young individual from high school who is picked on, beaten up, laughed at, and ridiculed with Korn performing inside the brain of the tormented boy. He seeks revenge throughout the video. The final scene shows him arriving at the school prom with an escort. He then vomits at those who had picked on him from across the auditorium, leaving them in disgust and humiliation.
