Saturday Morning Cartoon

Eat your Wheaties -- it's cartoon time!

You are watching The Mumbly Cartoon Show. From the video's description:
The Mumbly Cartoon Show was a Saturday morning cartoon produced by Hanna-Barbera Productions which aired on ABC from 1976-77.Mumbly is a cartoon dog character famous for his wheezy laugh, voiced by Don Messick. Mumbly bears a strong resemblance to Muttley from the animated series Wacky Races and Dastardly and Muttley in their Flying Machines. Like Muttley, Mumbly does not really talk; he mumbles and grumbles unintelligibly, and often uses his trademark snicker. Detective Lieutenant Mumbly's boss is Schnooker (inspired on Telly Savallas's Kojak detective and voiced by John Stephenson), an aptly named egotistical police chief who tries to take credit for nearly all of Mumbly's heroic deeds.
