It was one of my favorite seuss books growing up, so naturally I assumed everyone had heard of it. ah well. (practically no one has ever heard of my all-time favorite either, "The Butter Battle book".
I might rework the story to fix some elements I'm not happy with, and Twit might make an appearence in other fics because I like him too, but I think you're right, any more would be overkill on this one... but Thank you : )
