The Litterbug is a Donald Duck short released 21 June 1961.
Donald Duck and his nephews are litterbugs. They drop garbage everywhere they go, setting examples for various types of litterbugs: the unconscious carrier, the sports bug, the sneak bug, the highway bug, the beach bug, and the mountain bug. They are stopped by a policeman who makes them pick up everything they have dropped. Perhaps, Donald suggests, if we start at home, we can stamp out the pest, the litterbug.
