I watched this a some as a kid and enjoyed it. When I watched it as an adult I thought it was Jackie Mason and Dean Martin voicing the cartoon.
John Byner voiced the Ant and the Aardvark. He imitated Jackie Mason as the Aardvark and Dean Martin as the Ant.
The Ant and the Aardvark was a series of theatrical cartoons produced at DePatie-Freleng Enterprises from 1969 to 1971, about a blue aardvark always trying to catch a red ant named Charlie.
The series consisted of 17 cartoons that ran from 1969 to 1971. After its initial theatrical run, The Ant and the Aardvark later became a part of The Pink Panther Show, with all 17 episodes airing in reruns, with the characters themselves being integrated into later iterations of The Pink Panther itself.
When I watch the intro I can’t help but think Monsters Inc got a little inspiration from the beginning.
