The New Adventures of Lucky Luke Lucky Luke is the cowboy who shoots faster than his own shadow. With the help of his faithful horse Jolly Jumper (the world's smartest horse) and sometimes also Rantanplan (the world's dumbest dog) he maintains peace and order. In the wild west he hunts down desperadoes, keeps sharpshooters like Billy the Kid in check and constantly recaptures and returns The Daltons to prison.
