Chaser On The Rocks is a 1965 Wile E Coyote And The Road Runner cartoon directed by Rudy Larriva. It originally had a different ending than the one shown on TV today. It originally ended with the Coyote being fired into the setting sun. In the current version, the viewers only hear the boom of the cannon the Road Runner fires at the coyote. It's existence is very vague, although cartoonist historian Jerry Beck has confirmed it's existence.
