Scooby-Doo!: Behind the Scenes

It's revealed that Shaggy's childhood nickname was "Buzz" (in reference to his hairstyle at the time) and that he's currently a vegetarian. Shaggy discusses his unhealthy addiction to Scooby Snacks, which Velma claims at one point made up 45% of his body weight. To overcome this habit, he began collecting "decorator belt buckles" and believes to have the largest collection in the world, with 653. His favorite reads, "When Do We Eat?", although he claims to wear a different buckle for each mystery - they're just hard to see.
