Poor Pluto's no longer a planet;
The IAU voted to can it:
"The sun, it don't come nowhere near,
It ain't even close to a sphere,
And gravity 'nough it not hath
For cleaning up stuff in its path.
'Sides that, the way that we figger,
It's got a non-planet neighbor that's bigger."
Perspicacity (unwittingly comical)
From the kings of all things astronomical,
Who don't deserve one single kudo
For giving the boot-o to Pluto.
