“Cowboy Bob” is the tenth song on the Butthole Surfers' debut album, Psychic… Powerless… Another Man’s Sac. The song was another one of their early live staples, appearing on their first practice tape.

The high-pitched screams featured on this song come courtesy of Michiko Sakai, daughter of a Japanese WWII flying ace and then-wife of bassist Terence Smart.
