      The original phrase is pretty lame anyway. If you can’t do a thing, how can you be expected to teach it? I’d rather have a teacher that actually knows how to do the thing they’re trying to teach me.

        The saying isn’t trying to convey that people who can’t do something are well suited to teach it, it’s disparaging teachers by saying if they were any good at what they teach they would be doing it instead of teaching it.
