Train Trouble (1946)

Cartoon proof that breakfast is the most important meal of the day. In this 1940s cinema advert, the tardiness of Signalman Squirrel's breakfast brings passengers to the brink of a major rail disaster every day. The solution is not setting his alarm earlier, finding an extra pair of hands for his long-suffering wife, or (heaven forbid) making his own breakfast. No, the answer lies in a home delivery mix-up of a familiar cereal box.
