I saw a movie in the early 1970's that was an x-rated comedy. The movie was comprised of dirty skits. One was a scene of a big eyed, big nosed character talking. As the camera pulled back you realized it was an upside down penis with googly eyes on the testicles.
The movie was a double feature with Fritz the Cat, an x-rated animated film. Both were funny but I can't remember the name of the first movie.
