There’s something enormously comforting about a show that has absolutely the same plot every week.
Random trivia: Frank Welker, who played the original Fred (and has played Fred in many subsequent versions) is one of the most talented voice actors around. Check out his work in Futurama where he did many of the animal noises, including Nibbler.
Frank is also Scooby in the current incarnation, What’s New, Scooby-Doo?, which in my opinion is the best Scooby series since the original Where Are You?
Shaggy, Scooby, Velma, Daphne, Fred. Scrappy also. But I hate him. Scooby-Dum and Scooby-Dee often sucked. Never got Bogel and Weerd, but that was the 13 Ghosts of Scooby Doo series which had Scrappy. Scrappy is bad.
The Harlem Globetrotters, the Adams Family, Batman and Robin, Tim Conway, Dick Van Dyke, Mama Cass, Laurel and Hardy, Davy Jones, Don Knotts, Sonny and Cher, Three Stooge (twice), Phyliss Diller, among others.
Norville Rogers
Cacey Kacem used to do the voice of Shaggy. Don Messick is the best-known (and longest) voice of Scooby.
