I can remember him doing an interview on (I think) Howard Stern or something like that talking in his normal voice, and he was hilarious. I guess once you find a gimmick that pays though, you stick with it! RIP
That guy was a room divider. Almost an equal amount of people liked him as much as hated him. The irritating voice was his schtick.... a gimmick of his act. I thought he was hilarious. Then again, I really like to see people get offended or annoyed. Seeing someone get so bent out of shape just cracks me up.
