Similar story with Dave Chappelle too, I suppose.
Weed smoking comedian, with a high-pitched voice, gained tonnes of popularity with 'The Dave Chappelle Show' in the early '00's.
Made 3 seasons, then got offered something like $60 million to carry on making more. He buckled under the weight of the pressure, freaked out and disappeared.
No-one knew where he was, or if he was dead or alive! He turned up in Durban - South Africa, of all places, hiding under a rock.
It took its toll on him though, he didn't start performing again, until about 6/7 years ago, when he re-started his stand-up comedy act again.
Still funny as hell
! And oddly enough, his voice has dropped a few octaves. Now that he's in his 50's he sounds more 'husky'.
