Secretary of the Treasury William Gibbs McAdoo reacted to the sales problems by creating an aggressive campaign to popularize the bonds. The government used a division of the Committee on Public Information called the Four Minute Men to help sell Liberty Bonds and Thrift Stamps. Famous artists helped to make posters and movie stars hosted bond rallies. Al Jolson, Elsie Janis, Mary Pickford, Douglas Fairbanks and Charlie Chaplin were among the celebrities that made public appearances promoting the idea that purchasing a liberty bond was "the patriotic thing to do" during the era. Chaplin also made a short film, "The Bond", at his own expense for the drive. The Boy Scouts and Girl Scouts sold the bonds, using the slogan "Every Scout to Save a Soldier".
