The first was “The Road Runner cannot harm the coyote except by going “Beep-Beep.”
Here’s a gag from Hot-Rod and Reel (released in 1959).



Uh, what was that “discipline” again, Mark Twain?
Mike Maltese was the writer of this cartoon, and many others with the Road Runner. My recollection is he told (I think it was Mike Barrier) he had never heard of any “disciplines” when he had to come up with a story.
When I was a kid, a Road Runner cartoon was a good excuse to go into the kitchen and make a sandwich. I didn’t need to see the cartoon. I knew the Coyote would fail and this would happen.
In this short, the first two gags ends with the coyote going off a cliff.
Years later, watching the cartoons, I found some gags that did not involve cliffs, and were actually pretty creative. That couldn't be helped when you put Jones and Maltese together.
Personally, I prefer the “Super Genius” Wile E. Coyote who turns out not to be vastly superior in intellect to Bugs Bunny, but you know that old saying about mileage.
