Well, rule 4 was broke.
While he is generally silent in the Coyote-Road Runner shorts, he speaks with a refined accent in these solo outings (except for Hare-Breadth Hurry), beginning with 1952’s Operation: Rabbit, introducing himself as “Wile E. Coyote—Genius”, voiced with an upper-class accent by Mel Blanc.
Speech. Coyote usually does not make a sound, unlike Road Runner, who gives off the occasional “meep, meep.” Instead, Coyote communicates with signs that display his emotion, such as “ouch” or “uh-oh.” He has been known to talk, however, when he is around Bugs Bunny (In that case, Coyote was voiced by Mel Blanc).
But I recall a short where Wile E Coyote was going thru a cook book and the various ways to prepare fresh road runner into a meal, and commenting how delicious they were.
