its eight war bond campaigns that called on people to save now (and redeem the bonds after the war, when houses, cars, and appliances would again be available). The War Bond drives helped finance the war. Americans were challenged to put at least 10% of every paycheck into bonds. Compliance was high, with entire workplaces earning a special "Minuteman" flag to fly over their plant if all workers belonged to the "Ten Percent Club". Hollywood Hollywood studios also went all-out for the war effort, as studios encouraged their stars (such as Clark Gable and James Stewart) to enlist. Hollywood had military units that made training films—Ronald Reagan narrated many of them. Nearly all of Hollywood made hundreds of war movies that, in coordination with the Office of War Information (OWI), taught Americans what was happening and who the heroes and the villains were. Ninety million people went to the movies every week. Some of the most highly regarded films during this period included Casablanca, Mrs. Miniver, Going My Way, and Yankee Doodle Dandy. Even before active American involvement in the war, the popular Three Stooges comic trio were lampooning the Nazi German leadership, and Nazis in general, with a number of short subject films, starting with You Nazty Spy! released in January 1940 - the very first Hollywood film of any length to satirize Hitler and the Nazis - nearly two years before the United States was drawn into World War II. Cartoons and short subjects were a major sign of the times, as Warner Brothers Studios and Disney Studios gave unprecedented aid to the war effort by creating cartoons that were both patriotic and humorous, and also contributed to remind movie-goers of wartime activities such as rationing and scrap drives, war bond purchases, and the creation of victory gardens. Warner shorts such as Daffy - The Commando, Draftee Daffy, Herr Meets Hare, and Russian Rhapsody are particularly remembered for their biting wit and unflinching mockery of the enemy (particularly Adolf Hitler, Hideki Tōjō, and Hermann Göring). Their cartoons of Private Snafu, produced for the military as "training films", served to remind many military men of the importance of following proper procedure during wartime, for their safety. MGM also contributed to the war effort with slyly pro-US short cartoon The Yankee Doodle Mouse with "Lt." Jerry Mouse as the hero and Tom Cat as the "enemy". To heighten the suspense,
