The Face on the Barroom Floor
Overview
A painter turned tramp (Chaplin), devastated by losing the woman he was courting as a wealthy man, finds himself drunk and getting drunker by the minute with some sailors at a bar until he's literally falling down. He keeps futilely trying to draw the woman's picture on the floor with a piece of chalk until he finally passes out cold (or perhaps dies, as in the poem) at the end of the film.
Laughing Gas
Overview
Although only a dental assistant, Charlie pretends to be the dentist. After receiving too much anesthesia, a patient can't stop laughing, so Charlie knocks him out with a club.
His Prehistoric Past
Overview
Set mostly in the Stone Age, a prehistoric king, with a harem of wives, rules a beach. Charlie arrives and falls for the king's favorite wife. In the end, it turns out to have been a dream; Charlie was asleep in the park.
