Shaggy and Scooby are interesting characters, two of the most major characters in American literature. I think it's fantastic, because they are cowardly characters. They believe in cowardice and sandwiches. Can you think of any in the realm of English-speaking literature, cowardly characters that you identify with? You're with them all the way - "Go, Shaggy! Go, Scooby!" The rest of the guys who drive the van? "Fuck off." Scrappy-Doo - a Magnum. Boom! "Thank you, Grandad."
Gals, I am not built for this. And I didn't bring my inhaler.
