“Judo chop chop chop!” is definitely from The Flintstones- Fred and Barney were somehow mistaken for spies, and captured by this evil organization. Barney remembered seeing “Jay Bondrock” (I suppose that was the Stone Age James Bond) taking out enemies with a judo chop. So, Fred and Barney went on a spree, beating up all the villain’s henchmen with a “Judo chop chop chop!”
But they didn’t do it in fake Oriental voices.
One cartoon that DID have a VERY stereotypical Japanese character who beat up villains while saying stereotypical things like “So solly,” was…
Joe Jitsu, from the old “Dick Tracy” cartoons.
