Rare-Do-Wells Puzzle

Quiz Guy John Chaneski says his wife, the poet Jennifer Michael Hecht, has pointed out that there are some people who shouldn’t be classified as ne’er-do-wells, because every once in a while, they do manage to do something right. Perhaps, she says, they should be called rare-do-wells. Inspired by that observation, John has crafted a quiz with answers that rhyme with ne’er-do-well. For example, what would you call someone who occasionally does some good and lives in a nudist colony? This is part of a complete episode.
