Tais-toi!

Tais-toi!, localized into English under the title of Ruby & Quentin, is a French comedy and caper film from 2003. Quentin is a simple-minded, petty thief and Ruby works for a crime lord. After Ruby continually refuses to speak a word during his incarceration, a detective decides to bring the two inmates together; Quentin had already driven two men crazy with his outgoing nature. When Ruby fakes a suicide attempt, Quentin follows suit in order to stay close to him and thus begins a recurring theme of Ruby's inability to elude Quentin even after he manages to escape from prison.
