There is hardly another figure I can think of more perfectly suited to his work than Mel Blanc. He voiced the Looney Tunes characters and gave them so much life and personality that they were able to "return the favor," as Mel Blanc described it: When a serious car accident put him in a coma, an ingenious doctor thought to address "Bugs Bunny" and "Porky Pig" - and they answered! The Looney Tunes characters had so much independent life that they pulled an unconscious Mel Blanc out of a coma.
You would think that a connection as powerful and inevitable-seeming as Mel Blanc and the Looney Tunes would have come about on an effortless, silver-platter basis, but that's not true. He had to show up at the Warner Brothers offices every Friday for eighteen months before he got in, and the only reason he got in was that the usual front-desk guy had dropped dead. It was the new, clueless guy that let him through.
