We all know that Bugs Bunny loves his carrots, but did you know that the man behind his voice was not as keen on eating them as his famous cartoon buddy? There are stories that Mel Blanc was allergic to carrots, but that is not actually true. However, he did have a personal distaste for them and found them difficult to chew and then swallow, and yet he could hardly avoid them due to the nature of his work.
So, considering he had to sound like he was munching on a carrot and talking with a mouth full of the orange vegetable, it did mean he had to eat them during his voiceover. However, he would get to the point where he would spit them out, partly due to being fed up with actually eating them in the first place.
Perhaps he would have preferred for Bugs Bunny to have enjoyed eating something else instead?
