In 1951 Hanna Barbera created a Tom and Jerry short called "His Mouse Friday" that was later banned from television for its racist content. In the cartoon, which you can watch here, Tom is stranded on an island and Jerry paints himself up with black soot to resemble a cannibal and scare Tom. You'll notice that Jerry's dialogue and the dialogue of the island natives is muted. I'm not sure why that is, but based on what I found while scrounging for information on this cartoon, the dialogue was removed because of offensive slang. That information doesn't come from any official source, so take that for whatever it's worth. Questionable content aside, I don't think this is the best Tom and Jerry I've ever seen, though the scene where Tom is cooking in the stew pot and throws away the onion is pretty funny. And if nothing else, it's a nice little piece of animation history for fans of the medium.
