"It's Bedtime"

Ninja Sex Party has "It's Bedtime", a heavy metal lullabye where Danny informs the listener that "It's fucking bedtime!," and that he has an army of demons to "rock you to sleep" and a jackhammer to provide "soothing vibrations." The song is also laden with various noisy things, such as loud cars (including a car chase complete with police sirens), bad jazz, and a pirate battle.
