Auguri professore (1997)

Explicit nudity (male genitalia). A young man briefly puts his penis in a glass of water he later brings to an older woman he has a crush for. Unaware of all this, she drinks the water and comments it tastes good. The scene is played for comedy but is very graphic.

A man and a young woman climb on a chair to grab some heavy objects from a high shelf. Another person enters the room and, since the two are standing pressed against each other, mistakenly believes they are engaged in sexual activity (the man appears to be thrusting, they are fully clothed). The scene is played for laughs.
