Cheaper by the Dozen is a 1950 American comedy film based upon the autobiographical book Cheaper by the Dozen (1948) by Frank Bunker Gilbreth Jr. and Ernestine Gilbreth Carey. The film and book describe growing up in a family with twelve children, in Montclair, New Jersey. The title comes from one of Gilbreth's favorite jokes, which played out in the film, that when he and his family were out driving and stopped at a red light, a pedestrian would ask: "Hey, mister! How come you got so many kids?" Gilbreth would pretend to ponder the question carefully, and then, just as the light turned green, would say: "Well, they come cheaper by the dozen, you know", and drive off.
