Personally, I'm proud for Pluto. When it was considered a planet, it was rather the red-headed stepchild of the Solar System: It was by far the smallest of the planets, and its orbit was by far the most eccentric and most inclined, and it was meddled with by both Neptune and its own moon to a degree far greater than seen elsewhere in the Solar System, and so on. By the standards of a planet, it's pathetic.

But now that it's recognized as a Kuiper belt object, that's all changed. It's not quite the largest nor the closest of the KBOs, but it's very near the top of both lists, out of a very long list of such objects. It's gone from being a pathetic planet to being a prince among the KBOs. That's, if anything, a promotion.
