An excuse for a whole bunch of astronomers to argue a lot and author new or updated books about Astronomy.
Q: How many planets are there?
A1: This week, last week, or next week?
A2: Nine; we've known that for years. No, other Pluto-like objects are planets too, so there are twelve. No, Pluto-like objects are not planets, so there are only eight.
Afterthought: Mercury isn't much bigger; can't we disqualify it too?

Stupid, ignorant, in the dark, not having a clue as to what's going on in the world, etc...The term derives from the fact that knowledge is often equated with light for it allows us to "see." The sun is the ultimate source of light and thus the ultimate symbol for knowledge. Anything far from it would by default be something that is also "far" from a source of knowledge in the way that Pluto is far from the sun. There's also the fact that Mickey Mouse's dog Pluto is an idiot.
I can't stand Pluto people. You know, those types that create more problems than they solve.
He's more Pluto than Pluto!

The only planet in our Solar System.
Promoted for being gargantuan compared to the other worthless rocks.
