Chuck Jones 'Rules'

Before Chuck Jones created animated series; The Roadrunner (a segment with Looney Tunes) he had created a set of rules for the characters to obide by throughout every episode. For example, Coyote but always attempt to harm Roadrunner, but never succesfully do so, and the only sound Roadrunner could ever make would be 'meep meep'. This is an example of rules set in production.
