I wonder if that character design wasn't the animators making fun of the voice artist for ripping off Phil Silvers' voice. You know how cartoon voice-over artists are infamous for that sort of thing.
But this is DIC, the absolute bargain basement for animation. Which means the entire show was drawn by a single Korean man who has no idea who Phil Silvers is.
Looking at it another way, it must suck to be a voice-over artist thinking you've created an original voice observed from life and then discovering the artists have just drawn the character to look like Phil Silvers. Way to point out my lack of talent, THANKS
