Bugs Bunny is interesting in that it had a large cultural influence. It also turned "nimrod" into an insult, when people misunderstood Bugs Bunny sarcastically calling Elmer Fudd "Nimrod". Nimrod is a mighty hunter from the Bible, and Bugs' expression was equivalent to calling somebody stupid "Einstein". So now "nimrod" effectively means "moron", though that wasn't the intention.
