Fast Black 1924 ( 2)

"Hunky" Dorrey and "Dinky Dubbs are on the run from the cops. They consider getting a job. After one gets his face blackened from a car's exhaust, they see an ad for a "colored Pullman porter". Mistaken identity due to accidental blackface drives the remainder of the plot. The two wind up on a train, where they run into the police again.
