Scooby's All-Star Laff-a-Lympics is a Saturday morning
cartoon produced by Hanna-Barbera for ABC in 1977. A parody
of the Olympic Games, the cartoon featured three teams of
H-B characters: the Yogi Yahooeys (led by Yogi Bear and
Boo Boo), the Scooby Doobies (led by Scooby-Doo and Shaggy
Rogers) and the Really Rottens (led by Mumbly and Dread
Baron). Snagglepuss and Mildew Wolf acted as commentators.
