6. Scooby-Doo, Where Are You! (CBS, 1969-1970)
The first of many cartoons to feature everyone's favorite cowardly talking Great Dane, this undisputed classic is formula genius. Four teens (preppy Freddie, stunner Daphne, nerd girl Velma, hippie stoner Shaggy) and Scooby-Doo are stranded somewhere with a ghost/monster problem when their van, the Mystery Machine, breaks down and they wind up investigating and unmasking some seemingly innocuous deviant who was dressing up and scaring people off to cover up a crime.
It took on a whole different meaning to us when we got hip to the sweet cheeba and realized that Shaggy and Scooby, with their "Scooby Snacks," insatiable hunger, and jumpiness, are high all the timeâ€”and yet they still contribute to society in a positive way. So go screw, Narcs!
