Well, technically, it wouldn't even be called "Breaking Bad" anymore, it would be called "Making Good." And in that (parody) version of Breaking Bad, Walter White actually gives up the meth game and takes up teaching as a means of paying for his cancer according to Thats Whats Up Comedy.

It's funny in concept out of sheer ridiculousness, although I don't think I'd watch this as a full-on show.
