The moon is arguably a planet since according to a common definition the earth and moon are a binary system. http://en.wikipedia.org/wiki/Double_planet
So unless you want to use terminology as loosely as possible then go ahead, let's call everything not fixed in the sky for a planet and have a conversation that makes as much sense as if we'd start to call every physical object for... "object".
"When I went over to his object last night, we started to suck each other's object but really I wanted to stick my object in his object. He hadn't gone to the object all day so I ended up with a lots of object on my object."
Or we could just go for the IAU definition and call the moon a moon and Pluto for a dwarf planet.

I seem to remember a definition not mentioned in the wikipedia article along the lines of 'if the center of gravity of the system lies outside the radius of the largest body, then the system is a binary planet system. if it lies within, the smaller object is a satellite.'
Seems like a very precise and reasoned definition.
edit: its mentioned in the second wiki posted

Well at least we managed a few pages before the usual anti-American bitches started butt hurt posting. Also if you don't like living here, kindly pack your shit up and get the fuck out.
Woke up early to watch it live and don't regret that. At least the start of this week is not that terrible.
Vulnerant omnes, ultima necat.

Apparently the signals are being beamed to not that far from me at Tidbinbilla. It's also where most of the Apollo 11 stuff went via, despite what Parks would like you to think.
The dishes there are powerful enough to blast a hole in the clouds and is a pretty awesome place to visit.
The poster formally known as Me.
I had intended to get up early to watch this but the comfort of bed was too much that even awesome science could not break its spell. Ah well, I'm sure there will be lots more cool shit to come out of this monstrous robot over the next decade.
Edit: beaten. At least, obligatory xkcd
R.I.P.The last communication with the rover was on sol 2210 (March 22, 2010)
On July 12, 2012 (Sol 3010) solar arrays produced 523 watt-hours and 21.49 miles (34,580.05 meters) was the total distance traveled from landing.
