Captain Caveman, possibly the hairiest cartoon character ever, was created by Joe Ruby and Ken Spears and produced by Hanna-Barbera Productions in the seventies. Caveman is sometimes used as an insult to suggest that a person combines a deficiency in intelligence and a propensity toward brute force.

The song samples a line by John Lennon from the song “Come Together” by the Beatles (“Got to be a joker, he just do what he please”), furthering the idea of acting on impulse, a common feature of the caveman image.
