Tais-toi!

Tais toi ! , also known as Ruby & Quentin in English-speaking countries, is a 2003 French comedy-crime caper film, directed by Francis Veber. Quentin, a dim-witted small-time thief, holds up a foreign exchange booth. Unable to get the money he wants, he asks for directions to the nearest bank. When the police are given this tip-off, Quentin runs into a cinema where Ice Age is showing. He is caught when instead of continuing to run, he sits down and enjoys the film. Ruby, a henchman of the crime lord Vogel, who has been having an affair with his boss' wife, is thrown into a jail after... getting caught hiding the loot that he stole from his boss in revenge for the death of his lover. In jail Ruby refuses to eat or speak, which concerns the jail's psychiatrist but fails to impress the detective in charge of the investigation, who sees through Ruby's ruse. At the suggestion of the detective, the two criminals meet after Quentin, an intolerable extrovert who has driven mad two other inmates, is put in with him.
