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.
A glimpse at Kasem's IMDb page proves just how deep his voice went.
And he seemed to have made quite the impression on the folks of "Saturday Night Live." He was impersonated seven times by Dana Carvey in the late '80s and early '90s. Kasem would ultimately drop through the famed sketch show in November 1993 during a "Duets" sketch.
