It's no secret that Casey Kasem's distinctive voice did some talking outside the radio box. The broadcasting icon, who died Sunday at 82, was best known to a generation of children hunkered down in front of a television as the voice of crime-solving Shaggy from the classic cartoon "Scooby-Doo."
He provided the voice of Scooby's sidekick, Norville "Shaggy" Rogers, from 1969 to 1997, reprising it again from 2002 until 2009. The video above shows Kasem channeling his cartoon alter-ego during a 1980's Jerry Lewis telethon to raise money for the Muscular Dystrophy Assn.
