Laff-A-Lympics is a Saturday morning cartoon produced by Hanna-Barbera for ABC. New episodes were combined with reruns for the second season titled Scooby's All-Star Laff-A-Lympics. It ran 24 episodes over the two seasons from 10 September 1977 through 28 October 1978.
In a spoof of the Olympics and the contemporary series Battle of the Network Stars, Hanna-Barbera characters organized into teams and competed each week for gold, silver, and bronze medals. The "Really Rottens" team featured Dick Dastardly's brother, the Dread Baron, and was captained by Mumbly. Though they won twice and tied once, they usually lost to the "Scooby Doobies" or the "Yogi Yahooeys".
