Well, there's always Eris (http://en.wikipedia.org/wiki/Eris_(dwarf_planet)), which if nothing else has the most apt name in the solar system... (Though they originally tried to name it Xena.)

"Hey guys, I found another planet."
"Wooo!"
"And it's bigger than Pluto. But still tiny. I think we have a problem. The more of these we find..."
"...Either everything's a planet, or Pluto isn't one?"
"Exactly. And people are going to argue about it for decades."
"So what do we name it?"
"Didn't the Greeks have a goddess of discord...?"
