Casey Kasem as Shaggy - MDA Telethon Plea

During a moment of a 1980s Jerry Lewis Telethon, Casey asked to speak as his famous cartoon alter-ego to help kids donate to MDA.

I feel sorry for the voice actors who have had to mimic this original voice of Shaggy. That's a hard act to follow.

[@skinkscat]

hearing shaggy say "some have muscular dystrophy" had a peculiar effect on me

[@ZaxPlooper]

Shaggy's last 1% of power was spent on this wonderful man. RIP Casey :(

[@HapPap81]

I would have never in a million years guessed that he did Shaggy's voice.

[@FourKaiju]

Hes now reunited with Scooby Doo.

[@Chaos_Fantasmic]

Hearing his voice as shaggy makes me sad knowing he's dead but happy cause shaggy's the best character :(

[@Opawesum]

This is really wholesome. I never knew Casey voiced Shaggy, I only knew him for his involvement with music. So this was a pleasant surprise. Casey Kasem was a great man.

It feels so odd to have Casey ask if people know about Scooby Doo. Now, it’s a universal thing!

[@peterkirgan6850]

Jerry didn't look impressed!!! He was always a miserable man who wasn't happy till he got his own way!!! God love Casey! Brilliant man with a heart of gold!!! Rip Mr kasem!!!

It was terrible what Casey Kasem’s gold digging wife did to that man and his daughter at the end of his days!

In addition to voicing Shaggy, he also did Robin on SuperFriends, also created by Hanna-Barbara.

Wow it’s surreal for me watching Casey doing the voice. So cute how the expression on his face and his eyebrows scrunch up while doing the voice.

What a legend, as soon as I hear this voice I start smiling, Rest In Peace
