I believe this is called the
Bank System; it consists largely of foreground transparencies that they scale, shade, & use over various background images. as an example, in the B&W, every time people flee in a mad panic, they use the same cels, the same sequence. There is an old guy in the audience scenes who seems to be saying, "hit him again, sonny" or perhaps, "way to go!" as he swings his fist. I have seen him in perhaps, 3 or 4 episodes.
