The show: A group of nosy kids and a big Great Dane stumble onto mysteries with spooky swamp monsters and Jonathan Winters. Well, not always with Mr. Winters, but he seemed to be there a lot. And that mystery machine van of theirs ... who knows what Shaggy was cooking up in there.
Typical villain: Glowing underwater ghost, shrieking ghost, abominable snowman.
Ability: Fred's muscle, Velma's smarts, Shaggy and Scooby's luck, and Daphne's ... ummm ... well, she was there.
Longevity: "Scooby Doo" has had many incarnations since its '60s cartoon debut, even a live-action film. There is still a new version running on Saturday morning cartoons. It will go on in some form forever. Rooby-Roo!
