This obscure 1934 short, produced for MetLife, was made to remind its audiences about why people should be careful and courteous when driving through a rather absurd premise involving two goblins that look like dark-colored snowmen ("Discourtesy" and "Carelessness") wreaking havoc and getting fairy tale characters into wrecks. Why? I don't know.
