Yankee Dood It (1956)

Elmer Fudd is the progressive King of industrial Elves. He visits an outmoded shoemaker's shop to extol the virtues of mass production capitalism to the shoemaker, whose pet cat, Sylvester, uses the magic word, "Jehosophat" to turn Fudd's elf helper into a mouse and chases him around the shoemaker's shop.
