Mel Blanc, the voice of Bugs Bunny and many other cartoon characters, got into a near-fatal car accident in 1961 that resulted in a triple skull fracture and a three-week-long coma. After many failed attempts to stir Blanc, his doctor tried a different tactic.
He asked, “Bugs, can you hear me?”
Blanc, in the voice of Bugs Bunny, responded, “What’s up, Doc?”
From this point on, the doctor was able to speak to him by addressing him as his characters until he was out of his coma.
