The Wonderful Wizard of Oz
On her way down the yellow brick road, Dorothy frees a Scarecrow from the pole on which he is hanging, applies oil from a can to the rusted joints of a Tin Woodman, and meets a Cowardly Lion. The Scarecrow wants a brain, the Tin Woodman wants a heart, and the Lion wants courage, so Dorothy encourages them to journey with her and Toto to the Emerald City to ask for help from the Wizard.
