Cartoon characters don't worry about this, and cartoon *artists* didn't always check that kind of thing back in the Good Old Days(tm)
Sure they did. It's just that from a comic/cartoon point of view, the thumb pointing outward makes the hand less flat and mitten-like. It's the same reason that a lot of cartoon characters have their pinkies offset just a little no matter what the hands are doing.
In the end, the rules and conventions of animation and comic art trump the physics and common sense. Always.
