 According to Chuck Jones (I) (qv), the idea for this cartoon came  about one day while he and the writers were trying to come up with a  new story for a Bugs cartoon. The producer in charge admonished  them, "I dont want no gags about bullfights. Bullfights arent  funny". The thought of putting Bugs in a bullfight hadnt even  occurred to Jones, who immediately hit upon it as a great idea, and  this resulting cartoon proved to be of the most successful in the  Bugs Bunny series.
