The Pirates of Penzance (1983)

There is no explicit sex or nudity in this film, but multiple instances of sexual themes and subtle adult humor (i.e. man falls off the ship and out of view but is seen next hanging off the breasts of the wooden maiden on the prow although it is obvious that they were not a realistic handhold for his fall; man is claiming to see "beautiful maidens" in a spy glass and says "What grace! what delicacy! what [moans with delight] ..... refinement!).
