Southern Exposure(1934)

In a musical parody of "Uncle Tom's Cabin", slaves pick cotton by the ton, Simon LeGree threatens Uncle Tom with a whip, and Krazy helps Little Eva run away on ice floes created by dumping out the blocks from an ice truck. When she dies and goes to heaven, Krazy attempts to trick St. Peter into letting him in too, but he falls earthward in time to wake up, it's all a nightmare he's been having at the theatre putting on a "Tommer" show.
