most awesome discussion sections in journal articles

What articles have the best discussion sections and conclusions? My request is selfish. There’s an article that needs an improved discussion section. When I write, I often consult publications that I consider models of good writing. However, I usually focus on the core argument, often presented at the beginning, rather than what happens at the end. So what are examplars? Feel free to promote your own articles if you really think you have a rockin’ discussion section.
