Corny Old 1950s Movie: Itâs All in Knowing How - Dorky FilmThis is a hilarious promotional film which, while nominally focusing on nutrition, follows the story of Bob, a high school football player who finds that his girlfriend thinks he is boring, his bowling score is no good, and his skills on the field arenât cutting it anymore. His football coach tells him that he isnât eating a balanced diet, and Bill gets a crash course in nutrition, 1950âs-style. Since this film was sponsored by the National Dairy Council, the nutrition information is heavily skewed toward dairy products. Bobâs little sister even brings him a bowl of ice cream while heâs studying to help keep his energy up. After the changes in his diet, Bill feels great, gets more sleep, and even his bowling game is better!
