Cuore di clown (2011)

Braciola is a clown unable to make people laugh. Tonino, the meanest man in town, blackmails Braciola's girlfriend Gioia and forces her to marry him. The clown interrupts the ceremony, wreaks havoc in the church, with the help of his pet rat, and runs away with Gioia. Many adventures, and yes, laughs, await ahead for our heroes.
