Time brings us “The 9 Rules of Every Wile E. Coyote and Road Runner Cartoon“.
The Looney Tunes universe had boundaries as severe as an Acme anvil to the head.
A list of rules for the creators of the Wile E. Coyote and Road Runner cartoons has been circulating online and the instructions explain why every episode was almost exactly the same.
Rules for the show include a restriction on dialogue (save for “Beep-beep!”), setting (“All action must be confined to the natural environment of the two characters — the Southwest American desert”) and outcomes (“The coyote is always more humiliated than harmed by his failures”). There’s even an instruction on who the real enemy of Wile E. is: “gravity.”
