"Hooker with a Penis" is a song by the American rock band Tool. It was released on September 17, 1996, as the seventh track off their second studio album, Ænima. The song is one of the heaviest tracks from the album, and perhaps one of the heaviest songs by Tool. Unlike the more progressive sound found on the rest of the album, the track has elements of hardcore punk and thrash metal especially toward the end with some of Danny Carey's fastest double bass drumming.
