The Great Gazoo or simply Gazoo is a fictional character from the animated series The Flintstones. He first appeared on the show on October 29, 1965. The Great Gazoo was voiced by actor Harvey Korman. Fictional biography The Great Gazoo is a tiny, green, floating scientist who was exiled to Earth from his home planet for inventing a Doomsday Device. Gazoo was discovered by Fred and Barney when his flying saucer crashed. Gazoo recognizes Fred and Barney's world as prehistoric Earth. Gazoo refers to Fred and Barney as "dumb dumbs" and constantly causes problems for them. He can materialize and dematerialize objects, teleport, freeze time, travel through time, de-age anyone, destroy the world, and perform other remarkable feats but when he attempts to help out Fred and Barney, he usually ends up causing even more trouble. The only people who are able to see Gazoo are Fred, Barney and the children; animals also can see him. A running gag is that Fred argues with Gazoo while Wilma believes that he is talking to himself. When their daughter, Pebbles, says "Gazoo", Wilma thinks Pebbles is sneezing. Development The creation of the Great Gazoo is attributed to writer Joanna Lee, who wrote more than 20 episodes of The Flintstones. He was based on Bill Moore, a design teacher from CalArts. The first draft of the episode that introduced the Great Gazoo was originally entitled "The Wizard of Ogg" and Gazoo's original name was "Professor Ogg". Other proposed names for Gazoo were Rip van Zonk, Hocus the Pocus, Dr. Puckwuck, and Shagelbextyzinkus (Ol' Shaggy for short). In her original character description, Lee described Gazoo as "a mirror, reflecting life's vicissitudes, vagaries, ritual magic and dreary reality. Simply, [Gazoo] is life, brought home to our two favorite life participants, Fred and Barney". Reception Because Gazoo is introduced into the show midway through the penultimate season and is considered by some to be an absurd character who alters the premise and dynamic of the show, he is often cited by fans and critics of the show as being an example of the show's having "jumped the shark". In all, Gazoo appeared in 11 episodes. Other appearances Apart from the original TV series, he appears in many commercials for Pebbles cereal like one where he sends Fred somewhere where he can have all the Cocoa Pebbles he wants only for Barney to be brought there as
