Pierino contro tutti (also known as Desirable Teacher) is a 1981 comedy film directed by Marino Girolami.

The film was a massive success at the Italian box office, and generated a brief series of sequels (in the main part non-official sequels) including a female version of Pierino, as well as a short lived subgenre of joke-films in which the plot basically consists of a series of jokes placed side by side.

[1][2] Rome: Peter (Pierino) is a precocious but mischievous boy who often plays pranks and makes jokes at school.

One day Pierino pulls a dirty trick on her, making her break an arm.

The substitute class teacher is a pretty girl Pierino falls in love with.
