Chuck Jones & 'The Rules'

In every looney tunes cartoon there is the protagonist and antagonist. In the Looney tune 'Road Runner and Cyote, we see that the Cyote is the antagonist and road runner the protagonist. Cyote always comes back each time with a better weapon but at the point where he goes and catches the road runner the weapon never seem to work or, the road runner gets trapped and somehow manages to escape. Normally the protagonist gets trapped and instead of the villain or antagonist to kill the protagonist instantly instead they make a trap that the protagonist could escape from.
