The old black&white cartoons that are shown on the billboard the Planet Express ship crashes into every opening. Has anyone indexed where the clips are from for each show?

The clips all appear to come from public domain cartoons, except for 1ACV13 (“Fry and the Slurm Factory”), which is a Simpsons short from The Tracey Ullman Show.
