I really love 'Courage The Cowardly Dog' which aires on Cartoon Network. Ringo did his voice in these episodes:
The Duck Brothers: Two ducks put a electric device on Muriel's head and she becomes a remote controlled Muriel. The Ducks do this so they can save there 3rd brother who is trapped in a kitchen and ready to be eaten by humans, eventually the same is done with Eustace. Courage talks to the Ducks and works out of plan to save their brother. Courage,Eustace and Muriel settle peace with the duck brothers.The Ducks go back home into space.
Ball Of Revenge: Eustace finally gets tired of Muriel treating Courage so well, so he does something to finally destory Courage once and for all. He gathers together Katz, Le Quack, the weremole, the cajun fox, the Black Puddle queen and the giant foot to destroy Courage!!! They capture Muriel and Courage comes to her rescue. Courage then plays a dodgeball game with him verus everyone else. The Duck Brothers sing a song at halftime (yeah, yeah, yeah!). Everyone throws things at Courage and he's beaten. He screams so loud the floor cracks and the bad guys go down it. Muriel makes Eustace sleep on the floor. Courage turns on the TV to see Fred with a shaver on screen...
