I thought this was important

"Out of the nonsense Walt would select the stuff that could be made into a film: comedy bits, funny lines, gags. The cartoons of that period were still being concocted and assembled in much the same way Mack Sennett had made live-action comedies: “Charlie, there’s some kid auto races going on down in Venice—grab a cameraman, go down there and see if you can come up with something funny.” Or, “Hey! They just drained Echo Park Lake, it’s all mud, that oughta be funny as hell!” That’s what we did. We took a locale, an occupation, a situation, or the basic premise of a popular feature and did a lot of gags, strung them together, built in a chase, and got out in under seven minutes."
