Bugs usually tries to placate his antagonist and avoid conflict but, when an antagonist pushes him too far, Bugs may address the audience and invoke his catchphrase "Of course you realize this means "war!"" before he retaliates in a devastating manner. As mentioned earlier, this line was taken from Groucho Marx. Bugs paid homage to Groucho in other ways, such as occasionally adopting his stooped walk or leering eyebrow-raising (in "Hair-Raising Hare", for example) or sometimes with a direct impersonation (as in "Slick Hare"). Other directors, such as Friz Freleng, characterized Bugs as altruistic. When Bugs meets other successful characters (such as Cecil Turtle in "Tortoise Beats Hare", or the Gremlin in "Falling Hare"), his overconfidence becomes a disadvantage.
