American radio personality and actor Casey Kasem was the first actor to voice Norville “Shaggy” Rogers in the “Scooby-Doo” franchise. In the mid-‘90s, when asked to voice Shaggy in a Burger King commercial, Kasem quit, because he was a dedicated vegan and supporter of animal rights. He eventually made his comeback as the voice of Shaggy for the 2002 series “What’s New, Scooby-Doo?” after negotiating that Shaggy become a vegetarian.
In more modern times, Kasem’s Shaggy would have a plethora of plant-based options from which to choose, including plant-based burgers and plant-based milkshakes.
