To demean another to make them feel as though they don't amount to anything. As the scientists did to Pluto.
It's okay Pluto, I'm not a planet either.

1) The planet farthest from the sun that we know of. Recently reclassified as a "Dwarf-Planet".

2) The dog that is owned by that down-syndrome mouse, Micky.

2) Micky Mouse's dog is Pluto.

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?
