The Erotic Memoirs of a Male Chauvinist Pig (1973)

Playing as a stream of consciousness diary film following the sexual exploits of a flippantly anti love and marriage (but pro-smoking) artist named Barney who narrates his thoughts on life into a portable tape recorder that he carries around everywhere, Pig wanders brilliantly between intentionally uncomfortable hardcore couplings and fully clothed sight gags and genuinely clever one liners.
