An Englishman, an American and a Frenchman walked into a theater or at least that’s the kind of audience Olivier Giraud is hoping for his one-man show about life in France's capital. "How to become Parisian in one hour" is a stand-up comedy show which pokes fun at the legendary rudeness of Parisian life but it's become a surprise success with locals too, playing to sold-out theaters despite being performed entirely in English.
