During the french revolution, the ruling class was famously beheaded, similar to the headless angel sitting in this scene. The reason the angel has been siting there since the french revolution is because, presumably, they were a victim of the guillotine. The joke is funny in part because, presumably, the person would be given the head back in the afterlife, but they haven't been.
