You Never Can Tell (also occasionally referred to as C’est La Vie) is a rock and roll song by Chuck Berry, composed while he was in prison and originally released in 1964. The song became briefly popular again, thirty years later, after the release of the Quentin Tarantino film Pulp Fiction. The music was played for a twist contest at the fictional restaurant Jack Rabbit Slim’s in which John Travolta as Vincent Vega and Uma Thurman as Mia Wallace danced for the contest’s main prize. Tarantino said that the song’s lyrics of Pierre and Mademoiselle gave the scene a uniquely 50’s French New Wave dance sequence feel.
