I think you're right about a cartoon connection - which could also explain the subsequent ratzafratz.

I don't recall seeing Muttley, but Hanna-Barbera churned out a lot of cartoons that I did see: Huckleberry Hound, Quick Draw McGraw, Loopy De Loop, The Flintstones, Yogi Bear, Top Cat.. - and the voicing got passed around promiscuously.
