The Gold Rush (1925)

The Tramp and Mack Swain's Big Jim claw at a tilting floor as their storm-blown cabin teeters over a cliff edge in Charlie Chaplin's The Gold Rush. Every step toward the door tips the cabin further, and Chaplin stretches the gag out until the audience is gripping the armrests along with them. The bread-roll dance gets quoted more, but this is the frame that shows how far Chaplin would go to build a single joke.
