"Night Prowler" is the final track on AC/DC's album Highway to Hell. The track has two breaths in quick succession at the start of the song, intended to create a tone of fear and loathing. It is known among other AC/DC songs for its slow blues rhythm, ominous lyrics, as well as its controversy stemming from its association with the Richard Ramirez serial killings in 1984-85. At the end of the song, lead singer Bon Scott mutters, "Shazbot! Nanu nanu!", two phrases used by Robin Williams in his character of Mork on the popular sitcom Mork and Mindy.
