Fallo! (also known as Do It! – English translation of Fallo! – and Private^[1]) is a 2003 Italian erotic anthology film co-written and directed by Tinto Brass. The title is pun on the term "Fallo!" meaning in Italian both "Do It" and "Phallus" and the plot consists of six independent vignettes.

1. ALIBI: Cinzia celebrates her seventh year of marriage with her husband in Casablanca. The vignette starts with the husband making Cinzia retell her gynecologist's visit with a sexy twist. The husband then arranges for her to have sex with Ali, a hotel worker. He assures a reluctant Cinzia that it will all occur naturally, leading to both the husband and Ali having sex with Cinzia.

The scheme was concocted by her boyfriend, Neapolitan chef Cyrus, so that they can open his own restaurant.
4. BOTTE D’ALLEGRIA ("Barrel Of Joy"): Raffaella regales her husband with stories of her affairs, some of which are very strange. Her husband enjoys this, and encourages her to keep cheating on him.
5. HONNI SOIT QUI MAL Y PENSE: In the beautiful village of Cap d'Agde, Anna has leisurely fun with Mrs. Helen and her husband, Scottish satirist Mr. Noel.
