you can't polish a turd

proverb You can't make something unpleasant seem more appealing than it really is—attempting to do so is often a futile effort. "Turd" is a slang term for a piece of feces. Look, man, your term paper was bad before, and all of your edits are just making it worse—you can't polish a turd, you know.
