胖子与瘦子 Le gros et le maigre

A small and thin barefoot slave (played by Polanski) plays a flute and beats a drum to entertain his large master who rocks in a rocking chair in front of his mansion. The slave jumps and leaps like a madman, wipes his master's brow, feeds him, washes his feet, shades him from the sun with an umbrella and holds a urinal for him.
