Hee! Well, at least that saves poor mom's bottom. (And the "and" in "needles and pins" used to always throw me when I was a kid.)

Found a small dot and said
"Planet! Ahoy!"
Pluto, alas, is
Naught but a dwarf and
Planetologically
Brings us no joy.

Mars is red
and Jupiter's big
and Saturn shows off its rings;
Uranus is built on a funny tilt, and
Neptune is its twin;
And Pluto, little Pluto, is a planetary pretender.

The group that tracks planets is different from the group that tracks 'minor planets'. They needed to define where that line was.
He went through the final definition and how it was produced. He then went through the details of the definition and gave arguments as to why it made sense.
Finally, the definition only applies to the IAU. What the general public calls a planet is a separate issue.
