Trivia: Two of the acts that audition for Porky are a man whose trained pigeons fly out of a window, and a fox who does a dangerous stunt involving drinking chemicals. These acts would be re-used in a 1957 Friz Freleng cartoon, "Show Biz Bugs", with Daffy Duck as the performer.

Trivia: When the Coyote is about to attack the Road Runner with an axe towards the end of the cartoon, look behind him and you can see a billboard saying "Jones Motel" - a reference to the Warner Brothers director Chuck Jones.
